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.

More Evidence of the Importance of Forests: They’re Even Bigger Carbon Sinks than Thought

Want to see clear connections between environmental degradation and economic struggles? Deforestation provides about as clear a picture as any example: the loss of ecological services (flood control, water and air purification, topsoil protection, etc.) have direct economic impacts ranging from disaster recovery costs to food prices to increased need for health care spending. And, […]

You’re likely also aware that evidence of past warming periods has fueled the argument that natural causes are […]

Earth Policy Institute: Restructuring the U.S. Transport System — The Potential of High-Speed Rail

By Lester R. Brown Aside from the overriding need to stabilize atmospheric carbon dioxide (CO2) levels to stabilize climate, there are several other compelling reasons for countries everywhere to restructure their transport systems, including the need to prepare for falling oil production, to alleviate traffic congestion, and to reduce air pollution. The U.S. car-centered transportation […]
