Wal-Mart aims to curb plastic bag use

Reuters
September 25, 2008

NEW YORK (Reuters) - Wal-Mart Stores Inc will give out fewer plastic shopping bags, and encourage shoppers to reuse and recycle them, as the retailer aims to slash its plastic bag waste by a third worldwide by 2013.

The plan is expected to cut the equivalent of 9 billion plastic bags from stores each year, and eliminate more than 135 million pounds of plastic waste globally in the next five years.

The world's largest retailer said on Thursday it aims to reduce plastic bag waste by 25 percent in its U.S. stores and 50 percent in other countries.

"If we can encourage consumers to change their behavior, just one bag at a time, we believe real progress can be made toward our goal of creating zero waste," said Matt Kistler, senior vice president for sustainability at Wal-Mart.

Wal-Mart's U.S. stores will begin selling a new 50-cent reusable bag in October, and its baggers will be trained to pack bags more efficiently. Earlier this month, its Mexico stores introduced reusable bags that cost one-third less than the previous ones.

The move comes amid a global push to curb the use of plastic bags, which environmentalists say can take up to 1,000 years to disintegrate and pose threats to marine life, birds and other animals.

GLOBAL TREND

Earlier this year, San Francisco became the first U.S. city to outlaw non-biodegradable plastic bags from large supermarkets, and the state of California has enacted a law that requires large stores to take back plastic bags and encourage their reuse.

China, which consumes 37 million barrels of crude oil each year to manufacture more than one trillion plastic bags, has banned the use of ultra-thin plastic bags, which are typically used once and then thrown away.

Countries such as Rwanda and Bangladesh have introduced plastic bag bans, while Italy is due to introduce a ban by 2010.

While environmentalists cheered Wal-Mart's campaign, some said it doesn't go far enough.

"We applaud their efforts, but 33 percent by 2013 is not a very aggressive goal. It's doable ... by 2010 or 2009," said Stephanie Barger, executive director of Costa Mesa, California-based Earth Resource Foundation, which runs the "Campaign Against the Plastic Plague."

A Wal-Mart spokesman referred comment on the plan's timing to the Environmental Defense Fund, the retailer's partner in developing the plastic cutback plan.

"I think the way they're going about it is the way that works for them," said Gwen Ruta, vice president for corporate partnerships at EDF. "They're going to try lots of different things, see what works best and move forward, but against clear, very measurable goals and timeline."

EDF said it has worked with Wal-Mart since 2005, when the retailer began to pursue green initiatives in earnest.

Ruta said Wal-Mart has been looking at different ways to cut down on plastic bag use, from training its baggers to pack bags more efficiently or possibly redesigning the bags.

Carbon Is Building Up in Atmosphere Faster Than Predicted

Washington Post
September 26, 2008

The rise in global carbon dioxide emissions last year outpaced international researchers' most dire projections, according to figures being released today, as human-generated greenhouse gases continued to build up in the atmosphere despite international agreements and national policies aimed at curbing climate change.

In 2007, carbon released from burning fossil fuels and producing cement increased 2.9 percent over that released in 2006, to a total of 8.47 gigatons, or billions of metric tons, according to the Australia-based Global Carbon Project, an international consortium of scientists that tracks emissions. This output is at the very high end of scenarios outlined by the Intergovernmental Panel on Climate Change (IPCC) and could translate into a global temperature rise of more than 11 degrees Fahrenheit by the end of the century, according to the panel's estimates.

"In a sense, it's a reality check," said Corinne Le Quéré, a professor at the School of Environmental Sciences at the University of East Anglia and a researcher with the British Antarctic Survey. "This is an extremely large number. The emissions are increasing at a rate that's faster than what the IPCC has used."

The new statistics also underscore the growing contribution to the world's "carbon budget" from rapidly industrializing countries such as China, India and Brazil. Developing nations have roughly doubled their carbon output in less than two decades and now account for slightly more than half of total emissions, according to the new figures, up from about a third in 1990. By contrast, total carbon emissions from industrialized nations are only slightly higher than in 1990.

"What's happening is the major developed countries' plans are converging for emissions growth that will stop and be able to come down significantly," said James L. Connaughton, who chairs the White House Council on Environmental Quality. "But that's being completely overtaken now by the increasing greenhouse gas emissions in developing counties. It underscores the need for a broader and more aggressive effort by the major economies to come together."

It is unclear how much industrialized countries will be able to reduce their carbon output in the years to come, regardless of whether developing nations seek to restrain their greenhouse gas emissions. The federal government predicts that U.S. fossil fuel consumption will increase, not decrease. Japan, Canada and several other countries that committed to reducing their carbon emissions under the 1997 Kyoto Protocol have fallen far behind in meeting their targets.

Moreover, new scientific research suggests Earth is already destined for a greater worldwide temperature rise than previously predicted. Last month, two scientists from the Scripps Institution of Oceanography and the University of California at San Diego published research showing that even if humans stopped generating greenhouse gases immediately, the world's average temperature would "most likely" increase by 4.3 degrees Fahrenheit by the end of this century. Writing in the journal Proceedings of the National Academy of Sciences, they based their calculations on the fact that new air-quality measures worldwide are reducing the amount of fine particles, or aerosols, in the atmosphere and diminishing their cooling effect.

The IPCC has warned that an increase of between 3.2 and 9.7 degrees Fahrenheit could trigger massive environmental changes, including major melting of the Greenland ice sheet, the Himalayan-Tibetan glaciers and summer sea ice in the Arctic. The prediction that current emissions put the planet on track for a temperature rise of more than 11 degrees Fahrenheit, Le Quéré said, means the world could face a dangerous rise in sea level as well as other drastic changes.

Richard Moss, vice president and managing director for climate change at the World Wildlife Fund, said the new carbon figures and research show that "we're already locked into more warming than we thought."

"We should be worried, really worried," Moss said. "This is happening in the context of trying to reduce emissions."

The new data also show that forests and oceans, which naturally take up much of the carbon dioxide humans emit, are having less impact. These "natural sinks" have absorbed 54 percent of carbon dioxide emissions since 2000, a drop of 3 percent compared with the period between 1959 and 2000.

Connaughton argued that the Bush administration's "major economies" meetings, a series of talks among both developed and rapidly industrializing nations, have moved the world closer toward achieving significant cuts in greenhouse gases because the group is developing a common measurement system for emissions and is exploring how different industrial sectors can commit to worldwide reductions.

"We are unquestionably moving toward each other," he said of the industrialized and developing countries, "but there's a ways to go."

But Moss, who characterized the latest round of negotiations as "a lot of talk but not much action," said the administration cannot expect emerging economies to constrain their carbon emissions when the United States has yet to adopt binding targets for cutting its greenhouse gases. He noted that since 1990, the United States has released about 30 gigatons of carbon into the atmosphere, compared with China's seven gigatons and India's one.

"We really do have to start showing some leadership and start doing some changes ourselves," he said. "If we did that, China and India, which are developing rapidly, would be willing to come along."


From Cradle to Grave: IBM Consulting Offering Helps Clients Make Products "Greener" - Cars, Electronics, Consumer Products, Etc.

IBM
September 2008

(CSRwire) ARMONK, NY -- (MARKET WIRE) -- 09/24/08 -- A new IBM (NYSE: IBM) consulting offering can help clients make their products more eco-friendly from development and manufacturing through delivery and use to end-of-life reclamation and recycling.

Ranging across products as diverse as cars, tractors, televisions, electric shavers, even food and clothing, the IBM Environmental Product Lifecycle Management offering assists clients in analyzing every phase of a product's existence and designing it to be environmentally friendly from the beginning. This includes considering the materials used to make and package it, the energy needed to produce it, transport and use it, and designing it to be refurbished or recycled when it's no longer useable.

"The days of using inordinate amounts of energy, toxic chemicals and wasteful packaging to create throwaway products that just get tossed in the landfill are coming to an end," said Mark Wilterding, IBM's global leader for product lifecycle management consulting.

"Governments, environmental advocacy groups, and most of all consumers are demanding that companies do better, and designing a product from the start to be eco-friendly throughout its lifetime is the most effective way to do that."

Increasing government regulations require that companies think about the overall ecological impact of their products or face rising penalties, while more and more customers are expressing a preference for "greener" products. Both expect companies to plan for energy efficiency and proper disposal of products at end of life. In addition, the rising costs of energy and materials associated with making, packaging and selling any product can have a significant impact on a company's bottom line.

Companies that take a comprehensive approach to designing environmentally friendly products can not only avoid penalties and increase efficiency while lowering costs, but also have the opportunity to increase market share and revenue. Oftentimes, such "green" products are extensions of a brand or even support new product innovation.

IBM has extensive experience with many of these design-to-disposal capabilities within its own operations. The company created its product stewardship program in 1991, covering design for recycling, use of recycled plastics, product energy efficiency, and use of environmentally friendly materials and processes. The company has offered take-back programs for some products since 1989, and IBM processes more than 49,000 metric tons of products and product waste annually, with less than 1 percent of it going to landfills.

IBM's Environmental PLM offering is relevant to product and service offerings across all industries, but in particular to clients in sectors such as automotive, heavy equipment, electronics, and consumer products ranging from food to apparel.

The offering provides an overall analysis of a product's lifecycle, taking into account current environmental concerns, regulations and business issues, and industry best practices. Based on that analysis, IBM can help the client understand any gaps in its current practices, develop realistic targets for reducing the environmental impact of its products and establish a strategic plan of initiatives to meet those targets.

From that plan, IBM can help the client build new design-for-environment capabilities, integrating them into existing processes to improve the environmental competitiveness of its operations and products.

Through this offering, IBM can help clients develop the following
processes:

-- Design for compliance -- ensuring products meet new regulatory requirements for energy usage, material safety, etc.;

-- Design for end-of-life management -- designing a product so that it is easy to refurbish and reuse or disassemble and recycle;

-- Lifecycle assessment and carbon footprint reduction -- reducing the environmental impact of producing the product, shipping it, use by the consumer, and reclamation and recycling, by evaluating carbon trade-offs through the manufacturing, distribution and transportation processes;

-- Material selection -- choosing materials that are renewable, recyclable and non-toxic;

-- Packaging design -- designing packaging to minimize waste and make it lighter and easier to recycle;

-- Project delivery acceleration -- reducing the time it takes to get eco-friendly products from the drawing board to market.

An IBM global survey on corporate social responsibility with more than 250 c-suite executives showed that most see CSR activities as an opportunity to gain competitive advantage and grow revenue.
Additionally IBM's biennial global survey of more than 1,100 CEOs showed that the majority of them plan to increase their investments in CSR by 25 percent over the next three years.

Environmental PLM joins a growing list of consulting offerings from IBM designed to help clients address CSR issues throughout their operations, including the Carbon Trade-off Modeler, the CSR Assessment and Benchmarking offerings, and Green Sigma(TM).

California launches broad effort to control hazardous chemicals

Los Angeles Times
September 30, 2008
Mike Wilson
Dave Getzschman For the Los Angeles Times
Mike Wilson, a professor at UC Berkeley, is engaged in the green chemistry movement to create nontoxic chemicals for market products. "We're talking about transforming a trillion-dollar industry from the molecules up," he said.
Two new 'green chemistry' laws focus the state program on the most dangerous substances.
By Margot Roosevelt, Los Angeles Times Staff Writer
12:05 PM PDT, September 29, 2008
California today launched the most comprehensive program of any state to evaluate, label and, in some cases, ban industrial chemicals that are linked to cancer, hormone disruption and other deadly effects on human health.

Gov. Arnold Schwarzenegger signed new legislation to shift the state away from a scattershot approach in which bills targeting hazardous chemicals in products such as jewelry, baby bottles, toys, mattresses, computers and cosmetics have passed or failed depending on the intensity of the lobbying and media attention.

 
Instead of a product-by-product approach, two new laws are designed to encompass 80,000 chemicals now in circulation, focus on the most dangerous, widespread substances first and control them at the manufacturing stage, before they leach into the air, water or human skin.

The legislation, Schwarzenegger said, propels California to "the forefront of the nation and the world. . . . With these two bills, we will stop looking at toxics as an inevitable byproduct of industrial production."

The so-called green chemistry laws come as public alarm is on the rise over dangerous substances in consumer products. But some experts fear California's efforts will fall short because the laws don't require industry to disclose information on their products' hazards and put the burden of proving harm on the state.

More than 164 million pounds of chemicals are sold each day in California in consumer and commercial products, a figure that does not include chemicals used in industrial processes.

Existing law only allows California to regulate the disposal of chemicals. One bill signed today, AB 1879, sponsored by Assemblyman Mike Feuer (D- Los Angeles), lays out a framework to regulate toxics over their life cycle. The second bill, SB 509, sponsored by Sen. Joe Simitian (D-Palo Alto) creates a scientific clearing-house for chemicals' effects.

The governor signed the bills on the factory floor of Los Angeles' Nelson Nameplate, a company that has cut back its use of dangerous solvents. The new laws, he said, would lead to "the most comprehensive green chemistry program ever established."

Michael P. Wilson, a UC Berkeley public health researcher and a leading figure in the green chemistry in California, said the new laws would make California "the first state to put its foot in the water of a modern, comprehensive approach to chemicals policy." But he added that "we have a long ways to go before these proposals will have measurable results."

New laws will be needed to force industry to provide information on chemical use and hazards, he said. Federal law, long criticized as weak by consumer groups, prohibits the Environmental Protection Agency from sharing such information with the states.

"California agencies do not know what chemicals are sold in the state, where they are sold, by whom, for what purpose, how people might be exposed or where they ultimately end up in the environment," Wilson said. "This is the same situation for all U.S. states. There are large public health data gaps."

Swapping Land for a Road to Somewhere Divides Alaskans

New York Times
September 30, 2008

A brown bear on the tidal flats in the Izembek National Wildlife Refuge. Alaska wants to build a 17-mile road through the refuge to connect two remote outposts.


Published: September 26, 2008

ANCHORAGE — Among the many bills Congress is considering before it recesses for the November elections is a proposed land swap between the State of Alaska and the federal government that would allow a gravel road to be built through a remote national wildlife refuge.

Skip to next paragraph
Jules Tileson

King Cove, Alaska, where residents now use a hovercraft to travel across the water to Cold Bay.

Environmental groups are lined up against the proposal, saying a road would threaten the pristine wilderness area. Building it would require cutting an approximately 200-acre strip through the Izembek National Wildlife Refuge on the Alaska Peninsula, a resting place for hundreds of thousands of migratory birds and other animals.

Alaska officials, led by Senator Lisa Murkowski, a Republican, say the road is needed to connect one tiny outpost, King Cove, to another, Cold Bay, so that the 800 residents of King Cove have reliable access, particularly in emergencies, to the all-weather airport across the water in Cold Bay.

The issue before Congress is whether to allow Alaska to swap about 43,000 acres of state land for the 200 or so acres in the Izembek refuge needed for the road, which would be a single lane and, though the exact route has not been determined, would require an estimated 17 miles of construction, at $1 million to $2 million per mile.

Though the proposed land swap has been a source of debate for years, some opponents are drawing new attention to it as an example of Congressional excess. They have compared it to the controversial Bridge to Nowhere in Ketchikan, Alaska, which was ultimately abandoned but has proved a thorn for the governor, Sarah Palin, in her campaign as the Republican nominee for vice president. Ms. Palin supports the land exchange and the proposed road through Izembek.

A road "is going to fragment and irreparably harm one of the most pristine and valuable wilderness and wetland areas in the Northern Hemisphere," said Nicole Whittington-Evans, the associate director of the Wilderness Society's Alaska office.

But supporters of the project say opponents are misrepresenting it. They point out that the basics of the proposed land swap have not been significantly altered since well before Ms. Palin took office, in December 2006. Furthermore, while the measure before Congress would give the Department of the Interior the authority to approve the project, no money would be set aside under the current bill and several caveats could delay or stop the project outright.

"There is no earmark request here," said Ms. Murkowski, the bill's sponsor in the Senate (Representative Don Young, a Republican and the state's lone Congressional representative, sponsored it in the House). "There is none pending. There hasn't been any that was asked for."

Ms. Murkowski said Democrats had demanded significant changes, including measures to require more environmental study and to give the interior secretary discretion to determine whether the project was in the "public interest."

Opponents, however, say the bill as they interpret it essentially directs the secretary to find that the proposal is in the public interest. If that were to happen, the road could be financed by the state using money from the federal Highway Trust Fund, instead of an earmark, according to state transportation officials and Ms. Murkowski's office. The road is not currently in the state transportation financing plan.

Versions of the bill have cleared key committees in the House and Senate and await floor votes. However, given the economic bailout plans Congress is considering, the prospect of a measure passing this year "looks grim," said Bill Wicker, a spokesman for the Senate Committee on Energy and Natural Resources.

If the road is not approved this year, it will not be the first time. In 1998, the Clinton administration opposed the road, being pushed by the Alaska delegation, and instead brokered a $37 million deal to provide a hovercraft across Cold Bay to improve transportation for medical evacuations; the plan also upgraded a medical center in King Cove. But the hovercraft just started operating last year, and residents say weather and high costs make its use unpredictable. The local government also says it costs about $100,000 a month to operate. Opponents of the road, however, say it, too, may be unusable in foul weather and they note that the hovercraft has conducted medical evacuations since it came into use. Residents say the road is a matter of public and economic health.

"They say those people over there will be killing all the ducks and ruining the environment and decimating the country," said Mayor Stanley Mack of the Aleutians East Borough, much of whose population is Native Aleut and Yupik. "Where do you get off saying that? We've been out here for 4,000 years, protecting the country."

The Izembek National Wildlife Refuge has long been overshadowed by its northern cousin, the Arctic National Wildlife Refuge, and the fight over building the gravel road has lacked the political tension of the fight over drilling for oil. But environmental groups have also long felt that building a road, on an isthmus between two wildlife-rich lagoons in the refuge, would threaten the welfare of a dwindling caribou herd and hundreds of thousands of migratory birds, including Pacific black brant and the threatened Steller's eider.

The 43,000 acres of state land, plus 18,000 more that a local village corporation run by Alaska Natives has offered as part of the swap, cannot compensate, they say. "We're talking about quality versus quantity," Ms. Whittington-Evans said of the Wilderness Society.

Critics also note that the designated landing area for the hovercraft in King Cove was placed more than 15 miles away from town, and that the road there follows a course that could easily be extended to Cold Bay.

One local official confirmed that the hovercraft access road had been intentionally built with the goal of one day extending it through the refuge.

"Yes, this community isn't backing down from building this road," said the official, Robert S. Juettner, the administrator for the Aleutians East Borough. "And one day it will succeed."

William Yardley reported from Anchorage, and Felicity Barringer from San Francisco.


No more plastic bags in Westport, CT

New York Times
September 30, 2008

Westport, Conn., this month became the latest of a handful of communities to ban some plastic bags. The bags, which have only a brief, useful life, can survive forever in landfills and are of enormous concern to not only environmentalists but local officials who are running out of places to put their trash.

Westport's ordinance will take effect in six months and applies to bags dispensed at checkout counters. Others, like dry cleaning bags, will be exempted. The aim is to reduce litter and encourage customers to tote their groceries in reusable cloth bags.

The town's stand is laudable but will have only a limited effect on what is, after all, a statewide problem. The Connecticut Legislature rebuffed a proposed statewide ban last year. Massachusetts and Maine considered similar bans and also backed down.

Americans use and dispose of at least 100 billion bags every year. Although the plastics industry points out that plastic grocery bags are made more from natural gas than petroleum, natural gas is not a renewable resource and contributes to global warming. And about only 5 percent of all plastic bags are recycled nationwide. The rest end up in the trash, hanging in trees or floating in water where they menace marine life.

Diabetes and Pollution

New Scientist
September 10, 2008

By Phyllida Brown

On July 10, 1976, a reactor at a chemical plant near the small town of
Seveso in northern Italy exploded, sending a toxic cloud drifting into
the summer sky. Around 18 square kilometres of land was contaminated
with TCDD, a member of the notorious class of industrial chemicals
known as dioxins.

The immediate after-effects were relatively mild: 15 children landed
in hospital with skin inflammation and around 3300 small animals were
killed. Today, however, the accident casts a long shadow over the
people of Seveso, who are suffering increased numbers of premature
deaths from cancer, cardiovascular disease and, perhaps surprisingly,
diabetes (American Journal of Epidemiology, vol 167, p 847).

To some diabetes researchers, Seveso serves as a warning to us all.
Ask why diabetes is epidemic in the 21st century and most people will
point the finger at bad diet, laziness and obesity. According to a
small but growing group of scientists, though, the real culprit is a
family of toxic chemicals known as persistent organic pollutants, or
POPs. If these researchers are right, POPs -- which include some of
the most reviled chemicals ever created, including dioxins, DDT and
PCBs -- may be key players in the web of events that lead people to
develop the disease.

The claim has yet to attract widespread attention from mainstream
diabetes research. Even its champions were initially surprised by it.
"I had never even heard of POPs until 2005," says Duk-Hee Lee, an
epidemiologist at Kyungpook National University in Daegu, Korea, who
led the work. Lee and her co-workers are now convinced, albeit
reluctantly, that they are onto something. "The hypothesis is one that
I wish were not true," says her colleague David Jacobs of the
University of Minnesota, Minneapolis.

Diabetes, and particularly its commonest form, type 2 (see "Sidebar:
Diabetes basics"), is practically everyone's business. The World
Health Organization estimates that it already affects 180 million
people worldwide, with the number predicted to more than double by
2030. Last year the epidemic cost $174 billion in the US alone,
according to the American Diabetes Association.

========================================================

Sidebar: Diabetes basics

Diabetes has two main forms: type 1 and type 2. About 90 per cent of
diabetics have type 2.

Type 1 diabetes is an autoimmune disease in which insulin-producing
cells in the pancreas are progressively destroyed.

Type 2 diabetes usually develops in adulthood, although it is now
increasingly common in children. In this form, the pancreas either
produces too little insulin, or cells in the liver, muscles and fat
tissues fail to use it properly. Type 2 is most common in inactive,
overweight people who carry their fat on their midriff.

========================================================

The standard explanation for type 2 diabetes is that it is a
"lifestyle disease" caused by laziness and gluttony. For at least a
decade, however, epidemiologists have known that people briefly
exposed to high concentrations of POPs face a modest increase in their
risk of developing diabetes later in life. Those affected include the
people of Seveso and US veterans who were exposed to dioxin-
contaminated Agent Orange during the Vietnam war.

Two years ago, Lee, Jacobs and others decided to see whether everyday
exposure to POPs is also linked to diabetes. To their surprise and
horror, they found that it is.

For most people, POPs are inescapable: meat, fish and dairy products
all contain them. They enter the food chain from sources such as
pesticides, chemical manufacturing and incinerated waste, and
accumulate in animals higher up in the chain. Once in the body they
take up residence in fat.

POPs have long been recognised as nasty substances: their effects
include birth defects, cancer, immune dysfunction and endocrine
disruption. Since the 1970s, various measures have been put in place
to phase them out -- 12 of the worst POPs, known as the "dirty dozen",
were banned in 2004 -- but despite these efforts, POPs remain a
significant presence in the environment and food chain, partly because
many are still in use in the developing world, and partly because
these chemicals can take decades to break down.

Role of fat

Prior to her 2005 introduction to POPs, Lee was working on a humble
enzyme called gamma-glutamyltransferase (GGT), which is essential for
maintaining antioxidant levels in the liver. She was puzzled to find
that obesity combined with an elevated level of GGT is a strong
predictor of diabetes, but obesity alone isn't. "I searched the
literature and finally got an idea," she says.

As it turns out, GGT has an essential role to play in removing some
pollutants, including POPs, from inside cells (Diabetologia, vol 51, p
402). Could increased GGT activity simply be a marker of exposure to
POPs?

To find out, Lee and her colleagues analysed data from more than 2000
people in the US National Health and Nutrition Examination Survey
(NHANES), which measured both diabetes status and bloodstream levels
of POPs, among other things. They discovered that people with high
levels of six different POPs in their bloodstream were much more
likely to have diabetes, regardless of obesity (see diagram). The six
POPs were chosen because they were detectable in at least 80 per cent
of the participants.

Taking into account factors such as weight, age, waist circumference
and ethnic group, Lee calculated that in people with the highest
combined levels of all six POPs the rate of diabetes was a massive 38
times greater than in those with the lowest levels (Diabetes Care, vol
29, p 1638). "The people who disagree with us will say it's all
noise," says Jacobs, "but it's pretty hard to get odds ratios of 38
with noise."

To her even greater surprise, Lee found that in people with
undetectable levels of POPs the expected link between diabetes and
body weight melted away -- those who were obese were no more likely to
have diabetes than their lean counterparts. "This suggests that POPs
may be a more fundamental factor in the risk of diabetes than
obesity," says Lee. "The absolute risk of diabetes was extremely low
among subjects with very low concentrations of POPs."

"The expected link between diabetes and body weight melted away" But
fat is not off the hook just yet. While obesity alone appears not to
be linked with diabetes, the study suggests that POPs plus obesity is
bad news, and the fatter you are the worse it gets. When the
researchers examined the link with body mass index, they found that in
people with high levels of POPs the odds of being diabetic were much
higher for the obese than the lean. This suggests that something about
excess fat may be enhancing the toxicity of POPs. "It appears that
obesity can increase the harmful effects," says Lee.

Of course, the findings do not prove that POPs cause diabetes. "This
is an association between two things, not direct evidence of a causal
link," warns Oliver Jones, an environmental biochemist at the
University of Cambridge. The idea deserves further investigation,
though, he says.

Lee and her colleagues acknowledge that their interpretation could be
stood on its head. If diabetes causes the body to become less
efficient at dealing with POPs, then higher levels of POPs in people
with diabetes could be an effect of the disease, rather than its
cause. Lee does not rule out this possibility, but thinks it unlikely.
She points to a 2003 study by other researchers that found no
relationship between diabetes and the rate at which POPs are
eliminated from the body (Journal of Toxicology and Environmental
Health, vol 66, p 211
).

The team also examined the link between POPs and a metabolic disorder
called insulin resistance, in which muscle, fat and liver cells fail
to use insulin properly and which often progresses to full-blown
diabetes. Once again, they found that people whose blood contained the
highest levels of POPs were most likely to have insulin resistance
(Diabetes Care, vol 30, p 622). The results add weight to the idea
that POPs may be playing a vital role in the disease pathway from
insulin resistance to diabetes, says Lee. "I am really excited about
this."

Even so, she acknowledges two obvious objections to her work. First,
while levels of POPs in the blood of Americans have been falling for a
couple of decades, the diabetes epidemic is just taking off. Lee
suggests that as obesity seems to make POPs more dangerous, its rising
prevalence may have cancelled out any health improvements that should
have followed the decline in POPs.

A second question is why, if POPs are central to diabetes, the
incidence of the disease is soaring not only in the meat-addicted west
but also in countries such as India, where many millions are
vegetarian. Lee's answer is that, while many POPs are banned in the
west, some are still used as pesticides in developing countries. "The
highest rate of increasing risk of type 2 diabetes is observed in Asia
and Africa, not North America with the highest obesity rate," she
says.

To try to slot POPs into the complex diabetes jigsaw, it is worth
taking a brief step into the mainstream to look at the role of fats,
or lipids, in the disease. Type 2 diabetes was once seen mainly as a
disorder of glucose metabolism. Now, says diabetes researcher Evan
Rosen of Beth Israel Deaconess Medical Center in Boston, the focus has
shifted, with many scientists considering that the primary problem
lies with the metabolism of fats.

For years, physiologists largely ignored fat cells, or adipocytes,
seeing them as little more than passive energy silos. Recently,
though, they have been revealed for what they are: highly active in
producing both hormones that regulate energy, and inflammatory
messenger chemicals that are important to the immune system (New
Scientist, 16 September 2000, p 36). If adipocytes malfunction, the
consequences can be widespread.

When we eat energy-rich foods, our bodies have to store any excess
energy not burned up by physical activity. Most is stored as fat in
adipocytes, but when these eventually fill up, excess lipid spills
over into other tissues, particularly the liver, muscles and the area
around the heart. The presence of this "ectopic fat" has been linked
to all sorts of health problems, including insulin resistance and
diabetes.

Just how might ectopic fat help to trigger diabetes, though? There is
no simple answer and researchers still disagree about the possible
mechanism. However, there are some clues.

In animals ectopic fat is known to attract the attention of the immune
system, which produces inflammatory messenger chemicals around it as
though it were an infection. Interestingly, people with diabetes have
chronically raised levels of these inflammatory chemicals, raising the
question of whether inflammation caused by ectopic fat could be a
factor in the disease.

Ectopic fat also causes problems when muscle cells try to burn it to
generate energy. In obese people this is a highly inefficient process,
probably because their mitochondria -- the cell's power plants -
function at a reduced capacity, says Rosen. Mitochondria in muscle
cells are already known to work less efficiently in people with
diabetes, and this year a team at Helsinki University Central Hospital
in Finland found similar changes in obese people with no symptoms of
diabetes (American Journal of Physiology -- Endocrinology and
Metabolism, vol 295, p E148)."You end up with a half-burned lipid,"
says Rosen.

He speculates that this half-burned lipid acts like a magnet for
reactive oxygen species (ROS), including free radicals and peroxides,
which then inflict damage to the muscle cells themselves. There is now
clear evidence that chronic damage from ROS -- known as oxidative
stress -- helps to drive cells into insulin resistance. "If you block
ROS, you can block insulin resistance," says Rosen.

If Lee is right, however, and POPs are at the root of diabetes, these
ideas tell only half the story. So how might POPs be involved? Again,
there are tantalising hints. Jones points out that POPs are known to
bind to a family of receptors on cell nuclei known as PPARs. These are
involved in lipid metabolism and are known not to work properly in
people with diabetes; the diabetes drug troglitazone works by
activating one member of the family, PPAR-gamma. People with an
inherited disorder of this receptor are unusually prone to insulin
resistance. Another intriguing link is that POPs are known to cause
mitochondrial dysfunction, which some researchers think is the root
cause of diabetes (Science, vol 307, p 384).

But none of this explains how POPs interact with obesity. It may be
that obese people simply have a higher load of POPs in their bodies.
Another possibility is that POPs in ectopic fat are particularly
dangerous. Perhaps, speculates Lee, adipocytes are a relatively safe
storage site for POPs. "Our body has to find some place to store
them," she says, "and in this sense, adipose tissue is a relatively
safe organ." The trouble might start when POP-contaminated ectopic fat
starts to build up in the muscles and liver, exposing the organs to a
direct toxic assault. "That way, the harmful effects of POPs could
become more serious," Lee suggests.

Clearly more work is needed to establish the precise link between POPs
and diabetes. For Jones, it is surprising that Lee's research has
remained relatively neglected, especially given its public health
implications. He does note, though, that other teams are starting to
investigate the hypothesis. Julian Griffin and others at Cambridge
have found that low-level mixtures of POPs can cause metabolic
disturbances similar to those seen in type 2 diabetes.

Rosen stresses that the lack of attention given to this research
should not be seen as an indictment of the work, but instead reflects
how deeply scientists specialise in their own areas. "We generally
stay inside our silos," he says. "It's incredibly difficult to move
outside of them." Another problem, says Jacobs, is that testing the
hypothesis to destruction would require complex and long-term studies
of the type that funding bodies are often reluctant to commit money
to.

If Lee is right, it is not good news for the diabetes epidemic. Even
though many POPs are being phased out, they will take decades to clear
from the food chain. Meanwhile, newer POPs such as brominated flame
retardants continue to be manufactured in large quantities.

There is perhaps one silver lining. If you need an extra incentive to
stay lean, eat less meat and keep active, then knowing that toxic
chemicals lurking in your body fat could be a sure route to diabetes
might just be the motivation you're looking for.

Carcinogens From Car Exhaust Can Linger

Science News
August, 2008

Cancer-causing agents' interaction with nanoparticles could make the
chemicals as harmful as cigarette smoke, lab study suggests


By Davide Castelvecchi

The daily exposure to free radicals from car exhaust, smokestacks and
even your neighbors' barbecue could be as harmful as smoking,
according to a new study. Many combustion processes, such as those in
a car, create tiny particles that may act as brewing pots and carriers
for free radicals -- chemicals believed to cause lung cancer and
cardiovascular diseases.

The findings are from Barry Dellinger of Louisiana State University in
Baton Rouge, who reported them August 17 in Philadelphia during a
meeting of the American Chemical Society. Whether the exposure equates
to smoking one cigarette or as many as two packs a day remains
difficult to determine, he added.

His team's lab experiments -- first described in the July 1
Environmental Science & Technology -- suggest that noxious chemicals
form on soot nanoparticles in the still-hot residue of combustion, for
example inside a car's exhaust pipe and catalytic converter.

The chemicals are hydrocarbon-based free radicals called semiquinones.
Similar chemicals usually degrade quickly if they float solo. But in
this case, the chemicals stay attached to the nanoparticles, and they
linger in the air for much longer than previously thought. "To our
enormous surprise, the free radicals survive hours, days, even
indefinitely," Dellinger says.

To mimic the conditions in car exhaust as it cools, Dellinger's team
used silica particles 100 nanometers wide and coated them with copper
oxide. The team then exposed the particles to a hot gas --
experimenting with a range of different temperatures -- containing
hydrocarbons typically produced in flames. All those ingredients are
common in the exhaust of motor vehicles and factories.

The researchers then examined the nanoparticles with magnetic fields
tuned to identify unpaired electrons, the feature that makes free
radicals highly reactive and potentially dangerous for living cells.
The data showed a signature typical of free radicals and similar to
that of semiquinone, a free radical found in cigarette smoke.

The free radicals, however, only showed up when the initial
ingredients had been mixed together at temperatures between 200 and
600 degrees Celsius. That means free radicals are unlikely to form
during the actual combustion, which takes place at higher
temperatures. Instead, they would likely form once the exhaust begins
to cool down.

David Pershing, a chemical engineer at the University of Utah in Salt
Lake City, says the findings are potentially significant for human
health.

Dellinger added that more research is needed to determine not only
where someone would be exposed, but also how much the body would
absorb.

The exact amount of risk the pollutants pose is hard to estimate,
Dellinger said during his presentation. Data on atmospheric pollution
provided by the Electric Power Research Institute of Palo Alto,
Calif., suggests that the risk could be equivalent to smoking as
little as one cigarette a day or as much as more than two packs a day,
he said. "It's early in the game, and there's a lot of ways of doing
these calculations."

The free radicals discovered by Dellinger's team would not show up in
ordinary smog checks, which detect molecules in the gas state and not
those attached to solid nanoparticles, he said.

Even the most modern catalytic converters may be ineffective at
eliminating the free radicals. Ironically, even as a catalytic
converter breaks down smog-causing pollutants, it may be creating
conditions (particularly high temperatures) for the free radicals to
form. "You could be destroying some [pollutants] and creating some at
the same time," Dellinger says.

Debunking the Waste-to-Energy Scheme

Rachel's Environmental News
August 23, 2008

By Neil Seldman

Like any other vampire, "waste to energy" technology, e.g., burning
garbage for electricity, needs a good, swift stake to the heart.

Decades after garbage incinerators disappeared from U.S. cities,
burning garbage with energy recovery made a dash for federal, state
and city subsidies following the energy crisis in the l970s and '80s.
It had a brief flurry of activity but, by the time the '90s hit, was
on the decline. Only 30 of 300 proposed plants were ever built -- the
last ones in l995 as the result of some dubious political shenanigans
in Syracuse, New York and Montgomery County, Maryland.

The scheme is more aptly described as "wasted energy," as the energy
produced through incineration at the plants is quite small compared to
the amount of energy needed for extraction, processing and
distribution, to replace the materials destroyed.

While environmental dangers from acid gasses, dioxin, particulates,
lead and mercury alerted citizens to the dangers, the proposed plants
were really outdone by the financial weight of the capital outlay --
the operating costs and liabilities that a community had to undertake
to build 1,000-ton-per-day facilities or larger. Detroit spent $1.2
billion to support a garbage incinerator for 200 years. The city
council and mayor just cancelled any further dealings with the
facility. In New Jersey, former governor Christine Todd Whitman had to
drain the general budget of over $1 billion to bail out five county
incinerators, as haulers could not afford to pay the tip fees needed
to sustain the finances of plants and they took their trash to cheaper
landfills in Pennsylvania.

No amount of subsidies, including arbitrage bonding, exemptions from
hazardous waste regulations, mandatory purchase of electricity, put or
pay contracts, tax credits and court rulings could sustain such
financially and environmentally outlandish technologies. The companies
offering these technologies ended their runs. This was no small
accomplishment for the millions of citizens and small business owners
who banded together in a spontaneous grassroots movement to gain
control over the decision-making process at the local level. These
citizen-activists reclaimed America's birthright of local democracy,
despite harassment, including SLAPP (Strategic Lawsuit Against Public
Participation) lawsuits.

Now a new wave of Wall Street consortia have pooled their billions and
adopted a 'new' wave of technologies -- plasma arc, pyrolysis and
gasification. These so-called non-incineration technologies gasify
garbage and burn the gas. Proponents scold citizens and reporters who
refer to these facilities as incinerators.

Frederick, Maryland officials made it easier to settle this dispute.
They touted their new plan for a facility as non-incineration. When
opponents questioned them, they directed them to look at the facility
in nearby Montgomery County, Maryland, which was an old fashioned mass
burn, water wall incinerator.

You expect these new consortia to try to take advantage of the latest
energy crisis to make a killing. What is unexpected is the total lack
of due diligence on the part of both local officials and environmental
organizations.

Local officials in Florida, for example, are supporting a 3,000-ton-
per-day plasma arc incinerator (scaled up from a pilot plant of 100
tons per day) without knowing the actual costs involved, emissions
data, status of put or pay clauses, or which counties will commit
their garbage to what will be the largest garbage incinerator ever
operated in the world. Bradley Angel of GreenAction in San Francisco
dubs these facilities "incinerators in disguise."

Citizens in Los Angeles seem to have put the proper parameters on
their city, which is evaluating these new alternative technologies.
L.A. citizens will only allow consideration of waste-to-energy
technologies if they are scaled at not more than 10% of the waste
stream and no materials set aside for recycling are incinerated.
Citizens have shown their support for modestly scaled (300 tons per
day) biological systems, which generate methane from organic matter.
To its credit, the city is listening to its citizens and has
implemented diverse programs to reduce the materials placed in the
waste bin and increase materials going into the compost and recycling
bins.

The state of Florida has taken the opposite course. A recent law calls
for 75% recycling, but will count garbage that is incinerated as
recycling. Paper and plastic set aside for the BTU-hungry incinerators
can claim recycling. Meanwhile hundreds and thousands of cities and
counties are solving their problems their problems with no landfill
extensions and no incinerators. Recycling rates in towns that don't
kid around are hitting the 60% level, headed toward 70 and even 90% by
2025. A vibrant take-it-back network, which confronts the unfunded
mandates of products and packages designed for immediate disposal are
aggressively challenging manufacturers in the North West, New England
and California through stewardship councils that pinpoint products and
packages that are hard to recycle and/or contain hazardous materials.
Manufacturers are being pressured to pay for the financial burden they
place on households and businesses.

Many manufacturers have responded with zero waste pledges and
accomplishments. Grocery chains are striving for zero waste at the
checkout counters, as well as recycling and composting the materials
that they generate in their stores. The concept and practice of zero
waste has entered into mainstream thinking and action. In one
generation, the U.S. recycling movement has matured into a zero waste
movement

Why is there a new wave of incinerator promotion? Wall Street greed is
understandable during a time of energy and economic panic. Not only do
the venture capitalists seek to gain fortunes from cities and counties
for the facilities, but Wall Street firms will issue billions of
dollars in bonds at great profit to them and participating investors.
Incumbent officials always love bond issues as it leads to financial
patronage. The large hauling firms support incinerators as a way to
keep the status quo of mass disposal intact. Virgin materials
corporations want to see recycled materials incinerated and remove
10,000 local governments from competing with them as suppliers of
secondary materials, which compete directly with raw materials
extracted from nature.

While some national environmental organizations have closed ranks with
the big manufacturers, the grassroots environmental movement is
steadily growing in size and ambitions. Demanding zero waste in 2008
is a far more radical proposition than calling for recycling and
composting in the '80s and '90s. Activists are taking on the core of
the system.

The key fault line appears to be at the county and city level. Despite
new calls for green cities and counties, officials seem to have lost
the forest for the trees. The single largest thing a city or county
can do to add to its local economy and reduce its global environmental
footprint is to transform its waste stream into a resource stream.
Local governments are totally in charge of what they do with these raw
materials. Yet, despite the success of small towns, large cities and
rural counties in approaching zero waste (90% or more diversion from
landfill and incineration), elected officials seem to be asleep at the
switch -- falling for the huckster's call for an easy fix to the
garbage and energy crises.

Green idealists fail to make grade, says study

The Guardian
September 25, 2008

People who believe they have the greenest lifestyles can be seen as some of the main culprits behind global warming, says a team of researchers, who claim that many ideas about sustainable living are a myth.

According to the researchers, people who regularly recycle rubbish and save energy at home are also the most likely to take frequent long-haul flights abroad. The carbon emissions from such flights can swamp the green savings made at home, the researchers claim.

Stewart Barr, of Exeter University, who led the research, said: "Green living is largely something of a myth. There is this middle class environmentalism where being green is part of the desired image. But another part of the desired image is to fly off skiing twice a year. And the carbon savings they make by not driving their kids to school will be obliterated by the pollution from their flights."

Some people even said they deserved such flights as a reward for their green efforts, he added.

Only a very small number of citizens matched their eco-friendly behaviour at home by refusing to fly abroad, Barr told a climate change conference at Exeter University yesterday.

The research team questioned 200 people on their environmental attitudes and split them into three groups, based on a commitment to green living.

They found the longest and the most frequent flights were taken by those who were most aware of environmental issues, including the threat posed by climate change.

Questioned on their heavy use of flying, one respondent said: "I recycle 100% of what I can, there's not one piece of paper goes in my bin, so that makes me feel less guilty about flying as much as I do."

Barr said "green" lifestyles at home and frequent flying were linked to income, with wealthier people more likely to be engaged in both activities.

He said: "The findings indicate that even those people who appear to be very committed to environmental action find it difficult to transfer these behaviours into more problematic contexts."

The team says the research is one of the first attempts to analyse how green intentions alter depending on context. It says the results reveal the scale of the challenge faced by policymakers who are trying to alter public behaviour to help tackle global warming.

The study concludes: "The notion that we can treat what we do in the home differently from what we do on holiday denies the existence of clearly related and complex lifestyle choices and practices. Yet even a focus on lifestyle groups who may be most likely to change their views will require both time and political will. The addiction to cheap flights and holidays will be very difficult to break."

The frequent flyers said they expected new technology to make aviation greener, echoing comments made by Tony Blair last year, who said it was "impractical" to expect people to take holidays closer to home. He said the solution was "to look at how you make air travel more energy-efficient, how you develop the new fuels that will allow us to burn less energy and emit less."

EPA says rocket fuel pollutant perchlorate can remain in water

Los Angeles Times
September 23, 2008
WASHINGTON -- The Environmental Protection Agency says there's no need to rid drinking water of a toxic rocket fuel ingredient that has fouled water supplies around the country, including in California.

The EPA's conclusion is in a draft document not yet made public but reviewed Monday by the Associated Press.

Perchlorate has been found in at least 395 sites in 35 states at levels high enough to interfere with thyroid function and pose developmental health risks, particularly for babies and fetuses, according to some scientists.

The EPA document says that mandating a cleanup level for perchlorate would not result in a "meaningful opportunity for health risk reduction for persons served by public water systems."

Perchlorate is particularly widespread in California and the Southwest, where it's been found in groundwater and in the Colorado River, a drinking-water source for 20 million people. It also has been found in lettuce and other foods.

In absence of federal action, states have acted on their own. In 2007, California adopted a drinking-water standard of 6 parts per billion.

Massachusetts has set a drinking-water standard of 2 parts per billion.

Western states pitch plan to reduce greenhouse emissions

Los Angeles Times
September 23, 2008
Seven Western states and four Canadian provinces proposed a sweeping plan to crack down on global warming emissions today, across a region that represents 20% of the U.S. economy and 73% of Canada's economy.

The Western Climate Initiative, endorsed by the Western governors and Provincial leaders, would slash regional greenhouse gas emissions by 15% below 2005 levels in the next 12 years.

"We're sending a strong message to our federal governments that states and provinces are moving forward in the absence of federal action," said California Gov. Arnold Schwarzenegger, adding that the effort would spur renewable energy development and create "green jobs."

The initiative calls for a program to cap emissions that contribute to global warming, grant industries fixed numbers of permits to pollute, and allow them to trade the permits among themselves, so the emissions can be achieved in the cheapest way possible. Such a cap-and-trade program has been adopted in Europe, and the Northeastern U.S. is unveiling a more restricted version limited to power plants.

However, President Bush has opposed any national climate legislation, and a comprehensive global warming bill that would have set up a national cap-and-trade program failed in Congress earlier this year.

The Western initiative comes as studies have shown that the Western region of the U.S. is likely to suffer severe effects from expected climate change: water shortages, increased wildfires, coastal flooding and species die-offs.

California passed a global warming law in 2006 and is well ahead of its neighboring states in setting up a program to cap emissions. A regional program is designed to prevent industries from relocating to states that have less strict emission regulations.

But the recommendations issued today are no guarantee that state legislatures outside California will adopt the program.

Affected industries, from electrical plants to cement factories, are hoping to postpone or weaken state rules until a national program is adopted.

The Western initiative, however, gives industries considerable flexibility by allowing up to 90% of pollution permits to be given to industry, rather than auctioned off as environmentalists and consumer advocates had hoped. An auction would create funds to subsidize clean energy and prevent what environmental groups call "a free ride for polluters."

Rather than reduce all their own emissions, industries could reduce only 51% of them and then purchase "offsets" in other ways, such as planting trees, or paying to capture landfill emissions, under the Western initiative. Economists have expressed concerns that many offsets used in the European cap and trade program have proved to be bogus. In many cases, they have not reduced pollution beyond what was already planned.

The seven states are Arizona, California, Montana, New Mexico, Oregon, Washington and Utah. Environmentalists fear that polluting industries could flee to Nevada, Colorado or other non-member states. The four Canadian provinces are British Columbia, Manitoba, Quebec and Ontario. All together, the participating jurisdictions have a population of 84.6 million people.

Pharmaceuticals affect more U.S. drinking water

Water Business Wire
September 18, 2008
In March AP reported that test of drinking water in major U.S. cities found trace amounts of pharmaceuticals; 41 million people live in the affected cities; a new round of tests found that even more American -- 46 million -- are exposed to pharmaceuticals in water; even extremely diluted concentrations of pharmaceutical residues impair the workings of human cells in the laboratory.

Testing prompted by an Associated Press story which revealed trace amounts of pharmaceuticals in U.S. drinking water supplies has shown that the situation is even worse than initially thought, and that more Americans are affected by the problem than previously thought -- at least 46 million. This is up from 41 million people reported by the AP in March as part of an investigation into the presence of pharmaceuticals in the nation's waterways.
The AP's Martha Mendoza reports that the news service's stories prompted federal and local legislative hearings, brought about calls for mandatory testing and disclosure, and led officials in at least twenty-seven additional metropolitan areas to analyze their drinking water. Positive tests were reported in seventeen cases, including Reno, Nevada, Savannah, Georgia, Colorado Springs, Colorado, and Huntsville, Alabama. Results are pending in three others. The test results, added to data from communities and water utilities that bowed to pressure to disclose earlier test results, produce the new total of Americans known to be exposed to drug-contaminated drinking water supplies.

The overwhelming majority of U.S. cities have not tested drinking water while eight cities -- including Boston, Phoenix, and Seattle -- were relieved that tests showed no detections. "We didn't think we'd find anything because our water comes from a pristine source, but after the AP stories we wanted to make sure and reassure our customers," said Andy Ryan, spokesman for Seattle Public Utilities.

The substances detected in the latest tests mirrored those cited in the earlier AP report. Chicago, for example, found a cholesterol medication and a nicotine derivative. Many cities found the anti-convulsant carbamazepine. Officials in one of those communities, Colorado Springs, say they detected five pharmaceuticals in all, including a tranquilizer and a hormone. "This is obviously an emerging issue and after the AP stories came out we felt it was the responsible thing for us to do, as a utility, to find out where we stand. We believe that at these levels, based on current science, that the water is completely safe for our customers," said Colorado Springs spokesman Steve Berry. "We don't want to create unnecessary alarm, but at the same time we have a responsibility as a municipal utility to communicate with our customers and let them know."
Fargo's water director, Bruce Grubb, said the concentrations of three drugs detected there were so incredibly minute -- parts per trillion -- that he sent them to the local health officer to figure out how to interpret the information for the community. "We plan to put this into some kind of context other than just scientific nomenclature, so folks can get some level of understanding about what it means," said Grubb.

The drug residues detected in water supplies are generally flushed into sewers and waterways through human excretion. Many of the pharmaceuticals are known to slip through sewage and drinking water treatment plants. While the comprehensive risks are still unclear, researchers are finding evidence that even extremely diluted concentrations of pharmaceutical residues harm fish, frogs, and other aquatic species in the wild and impair the workings of human cells in the laboratory.

While the new survey expands the known extent of the problem, the overwhelming majority of U.S. communities have yet to test, including the single largest water provider in the country, New York City's Department of Environmental Protection, which delivers water to nine million people. In April, New York City council members insisted during an emergency hearing that their drinking water be tested. But DEP officials subsequently declared that "the testing of finished tap water is not warranted at this time."

EPA Lets Electronic Waste Flow Freely, GAO Report Says

Washington Post
September 17, 2008
The Environmental Protection Agency has done little to curb the export of discarded electronic products containing hazardous waste, much of which ends up in poorly regulated countries and harms the environment and public health, the Government Accountability Office concluded in a report being released today.

The 63-page report -- commissioned by House Foreign Affairs Committee Chairman Howard L. Berman (D-Calif.) -- is a scathing critique of the EPA's failure to control the export of used electronic equipment, which often is sent to China, India and other countries to be dismantled under unsafe conditions. U.S. authorities have yet to develop a national approach for handling the waste, which often contains toxic metals such as lead, mercury and cadmium. Amounts are rapidly growing as consumers replace their laptops, cellphones and televisions.

"It's a really inadequate situation that we've allowed to continue," said Berman, whose panel is holding a hearing on the issue today. "We have a regulation where, as far as I can tell, there's no effort to enforce it."

EPA spokesman Timothy Lyons took issue with the report, saying the agency is working hard to enforce a January 2007 rule that requires the EPA to oversee the export of cathode-ray tubes. "In the 18 months since the CRT rule went into effect, EPA initiated 20 investigations, recently issued one complaint and entered into one settlement," Lyons wrote in an e-mail. "Improving compliance with the rule is our top priority as we continue our efforts to educate the public and the regulated community about the new rule, and take enforcement action when necessary."

But it was GAO officials who alerted the EPA to violations by Jet Ocean Technology, a company in Chino, Calif., from which the EPA is now seeking a $32,500 penalty. Company officials could not be reached to comment yesterday. The report said that dozens of other U.S. companies are circumventing the CRT rule, while other electronics containing toxic materials are flowing overseas with no restrictions. The EPA cannot identify where 80 percent of U.S. electronic waste is headed, it said.

"U.S. law allows the unfettered export of nearly all types of used electronic devices," the report said. And though the agency has a regulation that governs disposal of cathode-ray tubes, the "EPA has done little" to set up an enforcement program.

Toxic materials in electronics do not leach out while the products remain intact, but once they are disassembled, the ingredients can enter the air and water. A 2007 study in the journal Environmental Health Perspectives found that children in Guiyu, a Chinese village where discarded electronics are dismantled, have lead levels in blood that are 50 percent higher than limits set by the Centers for Disease Control and Prevention.

Democratic Reps. Mike Thompson (Calif.), Gene Green (Tex.) and Bart Gordon (Tenn.) have tried for several years to broker a consensus on electronic recycling among the players, which include manufacturers as well as retailers and state and local governments.

"We're making progress," Thompson said, but "it's really hard to find any community of interest that says, 'Why don't you develop some laws and regulate and tell me how to do my business?' "

Thompson has drafted legislation calling for manufacturers to take more extended responsibility for their products and requiring manufacturers, retailers and recyclers to share the task of creating a national program to collect, transport, reuse and recycle electronic waste. Currently the issue is addressed by a patchwork of e-waste laws enacted by 16 states and New York City. Fifteen states require manufacturers to pay the cost of recycling their products.

Parker Bruggs, vice president for environmental affairs for the Consumer Electronics Association, said manufacturers, retailers, consumers and governments all must play a role. "Our position is it should be a shared responsibility among all stakeholders," Bruggs said. "It's really a resource conservation issue; there are valuable components in these products that can be reused."

The report said some U.S. recycling companies are lying about their environmental credentials. By setting up fictional brokers in Hong Kong, India, Pakistan, Singapore and Vietnam, GAO investigators found that 43 U.S. recyclers were violating the CRT regulations, yet nearly all of them touted their environmental friendliness on their Web sites. One Denver area company that illegally shipped CRT monitors overseas boasts on its Web site that "your e-waste is recycled properly, right here in the United States, not simply dumped on somebody else."

Some environmental groups, such as the Electronics TakeBack Coalition, argue that the United States should ban the export of all electronics that are due to be dismantled.
Casey Harrell, an international toxics campaigner for the advocacy group Greenpeace, said policymakers and consumers must also pressure manufacturers to make more environmentally friendly products in the first place.

San Francisco Resolution Calls for Legislation on Product Waste Responsibility

Market Watch
September 16, 2008
SAN FRANCISCO, Sept 16, 2008 /PRNewswire via COMTEX/ -- The California Product Stewardship Council (CPSC) applauds the San Francisco Board of Supervisors for adopting a resolution calling on state lawmakers to enact legislation that will shift costs and responsibilities for waste management from local governments to product producers.
The resolution calls for legislation based on the Extended Producer Responsibility Framework policy adopted by the California Integrated Waste Management Board (CIWMB) in January. The policy goal shifts waste management costs and responsibilities from being solely a local government responsibility to being primarily the responsibility of the producers of products. Producers are incentivized to redesign products to make them less toxic and wasteful, more durable and repairable, and easier to reuse, recycle, and compost.
"Our County is committed to continuing and expanding our support for EPR policies and environmental sustainability," says Supervisor McGoldrick, San Francisco Board of Supervisors.
San Francisco is the largest jurisdiction in California to adopt a resolution that calls for state elected officials to enact legislation supporting the EPR Framework approach. San Francisco's resolution adds to the growing support and momentum toward sustainable production. Other jurisdictions that have adopted similar resolutions include Butte County and the City of San Juan Capistrano.
"San Francisco is a shining example for other jurisdictions," says Heidi Sanborn, CPSC Executive Director. "We anticipate other cities and counties to adopt similar resolutions in the coming weeks and months."
Extended Producer Responsibility is a concept whereby product manufacturers assume primary responsibility for their products' life cycle. The "framework" policy is an alternative to current laws that address individual problem products like fluorescent lamps and batteries. The framework approach establishes consistent principles, clearly defined roles for all, and a transparent process for adding new product types.
Currently the State bans hazardous products from disposal without authority or plans for managing them, resulting in unfunded mandates on local governments and increases in government size, garbage rates, and taxes.
"San Francisco's resolution signals the beginning of the end to local governments providing 'free' disposal services to producers of toxic and throw-away products," says Bill Sheehan, Executive Director, Product Policy Institute, ( http://www.productpolicy.org), an organization that works with local governments to promote product stewardship policies.

GM unveils Chevrolet volt

Green Car Congress
September 16, 2008

General Motors marked its centenary today by unveiling the much-anticipated production version of the Chevrolet Volt extended range electric vehicle. The design of the Chevrolet Volt production car has changed from the original concept that was unveiled at the 2007 North American International Auto Show in Detroit. (Earlier post.)

Because aerodynamics plays a key role in maximizing driving range, GM designers created a more aerodynamically efficient design for the production vehicle than was represented by the concept. While design cues from the concept vehicle remain in the production Volt, the Volt's rounded and flush front fascia, tapered corners and grille are functional, enabling air to move easily around the car. In the rear, sharp edges and a carefully designed spoiler allow the air to flow off and away quickly. An aggressive rake on the windshield and back glass help reduce turbulence and drag.

The Volt uses electricity to move the wheels at all times and speeds. For trips up to 40 miles (under the EPA city cycle), the Volt is powered only by electricity stored in its 16-kWh, lithium-ion battery. GM uses half of the capacity (8 kWh) in its operating strategy for the Volt. When the battery's energy is depleted, a 1.4-liter, naturally aspirated gasoline/E85-powered engine range extender kicks in.

The Chevrolet Volt can be plugged either into a standard household 120v outlet or use 240v for charging. The vehicle's intelligent charging technology enables the Volt's battery to be charged in less than three hours on a 240v outlet or about eight hours on a 120v outlet. Charge times are reduced if the battery has not been fully depleted. GM estimates the cost of a daily 8 kWh recharge to be about $0.80 (10 cents per kWh).

The Volt's electric drive unit delivers the equivalent of 150 hp (111 kW), with 370 Nm (273 lb-ft) of instant torque, and a top speed of 100 miles per hour.

GM estimates that the Volt will cost about two cents per mile to drive while under battery power compared to 12 cents per mile using gasoline priced at $3.60 per gallon. For an average driver who drives 40 miles per day (or 15,000 miles per year), this amounts to a cost savings of $1,500 annually. Using peak electric rates, GM estimates that an electrically driven mile in a Chevy Volt will be about one-sixth of the cost of a conventional gasoline-powered vehicle. The cost savings are even greater when charging during off-peak hours, when electric rates are cheaper.

The Chevrolet Volt is expected to be built at GM's Detroit-Hamtramck manufacturing facility, subject to GM successfully negotiating satisfactory government incentives. Production is scheduled to begin late 2010 for models in the United States. Pricing has not been announced.
