United States Considers Ethanol Blend Increase
February 16, 2009 09:22 AM - Worldwatch Institute

The United States, the world's largest ethanol producer, is weighing options to boost domestic use of the controversial fuel, according to the country's new agriculture administrator. U.S. Department of Agriculture Secretary Tom Vilsack recommends that a higher percentage of ethanol be blended into gasoline to support the nation's struggling biofuel industry. The United States currently allows gasoline to contain a maximum of 10.2 percent ethanol, most of which is produced from corn.

D.C. proposes fees for paper, plastic bags
February 16, 2009 08:25 AM - innovations.harvard.edu/

District of Columbia legislators are considering imposing a 5-cents-per-bag fee on plastic or paper bags at liquor stores, grocers, drug stores and other businesses. The fee would be split between businesses and the city, with the District using its share to help clean the Anacostia River and offer free reusable bags to elderly and low-income residents.

Japan rules out 40 pct 2020 carbon emissions goal
February 13, 2009 10:54 AM - World Business Council for Sustainable Development

Japan has ruled out cutting greenhouse gas emissions by 40 percent by 2020 from 1990 -- the most ambitious possible action according to a reference target set by a U.N. panel of climate scientists. Agreeing a 2020 target to curb greenhouse gases is one of the most contentious aspects for rich countries of U.N. climate talks meant to end with a new treaty to replace the Kyoto Protocol in December this year. Japan is expected to announce its 2020 goal by June. The country argues that because it is so energy efficient already, it will be more expensive to meet the same emissions-cutting target of other rich countries.

CO2 hits new peaks, no sign global crisis causing dip
February 12, 2009 10:08 AM - Reuters

OSLO (Reuters) - Atmospheric levels of the main greenhouse gas are hitting new highs, with no sign yet that the world economic downturn is curbing industrial emissions, a leading scientist said on Thursday. "The rise is in line with the long-term trend," Kim Holmen, research director at the Norwegian Polar Institute, said of the measurements taken by a Stockholm University project on the Arctic archipelago of Svalbard off north Norway.

Why Global Warming May Be Fueling Australia's Fires
February 12, 2009 09:40 AM - Time

The raging infernos that have left more than 160 people dead in southern Australia burned with such speed that they resembled less a wildfire than a massive aerial bombing. Many victims caught in the blazes had no time to escape; their houses disintegrated around them, and they burned to death.

Aerosols: their part in our rainfall
February 12, 2009 09:29 AM - CSIRO Australia

"We have identified that the extensive pollution haze emanating from Asia may be re-shaping rainfall patterns in northern Australia but we wonder what impact natural and human-generated aerosols are having across the rest of the country," Dr Rotstayn said.

Merged climate, pollution fight seen saving cash
February 12, 2009 09:14 AM - WBCSD

Merging separate fights against air pollution and climate change could save cash and encourage developing nations such as China to do more to curb global warming, researchers said on Wednesday. "There are big gains to be made" from a combined policy, said Petter Tollefsen, a researcher at the Center for International Climate and Environmental Research, Oslo (CICERO).

What a slump in carbon prices means for the future
February 11, 2009 05:46 PM - New Scientist

It is getting progressively cheaper to pollute the atmosphere. The price of permits to emit carbon dioxide has crashed, falling to 9.30 euros ($12) per tonne of CO2 on Tuesday, close to the all-time low of 8 euros. In the medium to long term, this might affect the European Union's ability to meet its ambitious targets for reducing emissions by 20% by 2020 relative to 1990 levels. A low price is bound to have more immediate effects too.

Black Carbon an Easy Target for Climate Change
February 11, 2009 11:19 AM - Policy Innovations

Could the silver bullet for climate change be black? The particulate matter called black carbon—a type of soot from burning fossil fuels, biofuels, and biomass—is now estimated to be the second most potentgreenhouse warming agent after carbon dioxide. As a result, reduction of black carbon has gained momentum as one of the fastest means to significantly impact global warming.

U.S. stimulus would cut climate emissions: report
February 9, 2009 09:50 AM - Reuters

WASHINGTON (Reuters) - Energy efficiency and conservation proposals in President Barack Obama's original economic stimulus plan would cut climate-warming carbon dioxide emissions by 61 million tonnes a year, a new report says. That would be equivalent to eliminating the greenhouse gas emissions from electricity used in 7.9 million U.S. homes or taking 13 million cars off the road, the analysis of the recovery plan's carbon footprint found on Thursday.
