News release: “For the sixth consecutive year, the U.S. Environmental Protection Agency (EPA) is reporting a decrease in average carbon dioxide (CO2) emissions and a slight increase in the average fuel efficiency for new cars and light duty trucks, according to EPA’s annual report Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends: 1975 through 2010. EPA projects a small improvement in 2010, based on pre-model year sales estimates provided by automakers, to 395 grams of CO2 per mile and 22.5 miles per gallon (mpg), though there is uncertainty in these projections as they were made during the atypical automotive market in 2009. The 2010 final data will be available in next year’s report.
