High gasoline prices, a slow economy and – ironically enough – a cool summer caused U.S. greenhouse gas emissions to fall nearly 3% in 2008 from 2007 levels, the Environmental Protection Agency reported today.
It’s the largest year-over-year drop that the EPA has recorded since it began tracking greenhouse gas emissions in 1990.
The 2009 decline will likely be even steeper: The federal Energy Information Administration reported this month that carbon dioxide emissions from fossil fuels, the major driver of American greenhouse gas emissions, fell more than 6% from 2008 to 2009.
