U.S. Carbon Dioxide Emissions Down 11 Percent Since 2007

Carbon dioxide emissions from burning fossil fuels in the United States peaked at more than 1.6 billion tons of carbon in 2007. Since then they have fallen 11 percent, dropping to over 1.4 billion tons in 2013, according to estimates from the U.S. Energy Information Administration. Emissions shrank rapidly during the recession, then bounced back slightly as the economy recovered. But shifting market conditions, pollution regulations, and changing behaviors are also behind the decline.

Regina Rochefort, a National Park Service science adviser at Mount Rainier, said the meadows surrounding the famous peak have been shrinking because of less snowfall and shorter periods of snow cover. In the past, the snow has […]

Better Buildings Best Way to Cut Carbon

A North American organization of energy experts issued a report that found that building more green buildings is the best way to cut carbon dioxide emissions (CO2), one of the major contributors to global warming. In fact, green buildings could cut emissions more deeply, quickly and more cheaply than any other global warming mitigation effort. […]
