Stagnant Mileage Demands Better Answers From Congress Administration

Washington, D.C. — The average fuel economy of U.S. autos will remain unchanged from 2005 to 2006 according to the U.S. Environmental Protection Agency (EPA), despite high gasoline prices and better technology entering the market, including hybrid vehicles, variable valve timing, and cylinder deactivation. EPA released its annual “Light-Duty Automotive Technology and Fuel Economy Trends” report on Monday. “The lesson is that better technology alone won’t get us the reductions we need in oil consumption and global warming gases.

Global Warming Emissions

Carbon dioxide is the predominant global warming pollutant, accounting for eighty percent of global warming emissions. Contrary to the goals set out in legislation recently considered in the U.S. Senate, emissions have continued to increase. Transportation is responsible for 32.3% of all carbon dioxide emissions in the U.S. While the U.S. has made progress in reducing vehicles' emissions of regulated pollutants such as ozone precursors, CO2 emissions from the transporatation sector continue to rise.
