Power plants are major influence in regional mercury emissions
The amount of mercury emitted into the atmosphere in the Northeast fluctuates annually depending on activity in the electric power industry, according to researchers at the Yale School of Forestry & Environmental Studies. view more (2006-07-24)
VTT opens research lab for heavy vehicle emissions
VTT, Technical Research Centre of Finland opens a new lab which is comprehensive and significant measured even by international standards. VTT`s new research laboratory for research of heavy duty vehicles will focus on truck and bus energy and emissions research. With the laboratory`s comprehensive facilities, it will be possible to combine VTT`s... view more... (2002-03-26)
Smithsonian scientists highlight environmental impacts of biofuels
Biofuels reduce greenhouse-gas emissions in comparison to fossil fuels. In the Jan. 4 issue of the journal Science, Smithsonian researchers highlight a new study that factors in environmental costs of biofuel production. Corn, soy and sugarcane come up short. view more (2008-01-04)
Scientists issue Bali climate change warning
More than 200 leading climate scientists have today warned the United Nations Climate Conference of the need to act immediately to cut greenhouse gas emissions, with a window of only 10-15 years for global emissions to peak and decline, and a goal of at least a 50 per cent reduction by 2050. view more (2007-12-07)
Carbon sinks losing the battle with rising emissions
The stabilising influence that land and ocean carbon sinks have on rising carbon emissions is gradually weakening, say scientists attending this week's international Copenhagen Climate Change Conference. view more (2009-03-17)
Biofuels: More than just ethanol
As the United States looks to alternate fuel sources, ethanol has become one of the front runners. Farmers have begun planting corn in the hopes that its potential new use for corn will be a new income source. view more (2007-04-06)
Tackling climate change with new permits to pollute
A new way to reduce carbon dioxide emissions and tackle climate change had been unveiled by leading economists. view more (2009-01-06)
Scrubbing sulfur
The Department of Energy's Pacific Northwest National Laboratory has developed a reusable organic liquid that can pull harmful gases such as carbon dioxide or sulfur dioxide out of industrial emissions from power plants. view more (2009-08-18)
Brazil demonstrating that reducing tropical deforestation is key win-win global warming solution
Tropical deforestation is the source of nearly a fifth of annual, human-induced emissions of heat-trapping gases to the atmosphere. view more (2007-05-16)
Siberian lakes burp "time-bomb" greenhouse gas
Frozen bubbles in Siberian lakes are releasing methane, a greenhouse gas, at rates that appear to be "... five times higher than previously estimated" and acting as a positive feedback to climate warming, said Katey Walter, in a paper published today in the journal Nature. view more (2006-09-08)
Nitrous oxide from ocean microbes
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing today. view more (2007-12-11)
First-ever 'State of the Carbon Cycle Report' finds troubling imbalance
The first "State of the Carbon Cycle Report" for North America, released online this week by the U.S. Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions. view more (2007-11-15)
Family planning a major environmental impact
Some people who are serious about wanting to reduce their "carbon footprint" on the Earth have one choice available to them that may yield a large long-term benefit - have one less child. view more (2009-08-03)
Simple measures can yield big greenhouse gas cuts, scientists say
New technologies and policies that save energy, remove atmospheric carbon and limit greenhouse gas emissions are needed to fight global climate change - but face daunting technological, economic and political hurdles, a Michigan State University scientist said. view more (2009-10-27)
Carnegie Mellon studies how climate change impacts food production
The old adage, "We are what we eat,'' may be the latest recipe for success when it comes to curbing the perils of global climate warming. view more (2008-04-22)
Plan to conserve forests may be detrimental to other ecosystems
Conserving biodiversity must be considered when developing plans to reduce greenhouse gas emissions from deforestation, researchers warn in today's edition of Science. view more (2008-06-13)
Soil emissions are much-bigger-than-expected component of air pollution
Nitrogen oxides produced by huge fires and fossil fuel combustion are a major component of air pollution. They are the primary ingredients in ground-level ozone, a pollutant harmful to human health and vegetation. view more (2005-06-07)
New report cites ethics and justice as critical in world's approach to climate change
Ethics, human rights, and distributive and procedural justice must be an integral component of international negotiations seeking any comprehensive solution to climate change, according to a new report released here today at the United Nations Climate Change Conference. view more (2006-11-08)
Vehicle emissions monitoring validates inspection program and offers policy insights
A long-term Georgia Institute of Technology study continues to validate the effectiveness of Georgia's vehicle emissions inspection program in 13 metro Atlanta counties that are part of a federal ozone level non-attainment area. view more (2007-06-18)
Device Burns Fuel with Almost Zero Emissions
Georgia Tech researchers have created a new combustor (combustion chamber where fuel is burned to power an engine or gas turbine) designed to burn fuel in a wide range of devices — with next to no emission of nitrogen oxide (NOx) and carbon monoxide (CO), two of the primary causes of air pollution. view more (2006-06-22)
