2010Apr1: The U.S. federal government establishes national greenhouse gas emissions standards for the first time. By 2016, new vehicles will be required to have a combined fuel economy average of 35.5 miles per gallon. The new rules are expected to reduce CO2 emissions and other greenhouse gases about 30% from 2012 to 2016 (New York Times).
