WASHINGTON (Nov. 20, 2009)—Carbon dioxide emissions from new vehicles have decreased for the fifth consecutive year, along with a corresponding increase in fuel economy, according to a new report from the U.S. Environmental Protection Agency.
Gas mileage decreased and carbon dioxide increased in the U.S. vehicle fleet between 1987 and 2004, according to the report. Thanks to a trend of improvement that began in 2005, however, both figures are now at levels prevalent in the early 1980s, it said.
Average carbon dioxide emissions have fallen 39 grams per mile, or 8 percent, since 2004, and average fuel economy has increased 1.8 mpg, or 9 percent, the report said.
