On April 15, 2011, EPA issued its 645 page emissions inventory showing that greenhouse gas emissions in the U.S. dropped 6.1% from 2008 to 2009. That is a significant drop in emissions. EPA's explanation for the decrease was twofold: (i) a decrease in U.S. economic activity, and (ii) less reliance on coal. No word yet from EPA on what to do about the increase in greenhouse gas emissions from China.
