Automakers' Strategies Aggravate Global Warming

Despite growing concern over global warming, major automakers still pursue product strategies that make the problem worse, a New York environmental organization says. Through 2003, carbon dioxide (CO2) emissions -- a primary cause of global warming -- from U.S. cars and light trucks have increased 25 percent above the 1990 level. Both the total CO2 emissions and the average emissions per vehicle continue to rise, according to a new report from Environmental Defense.
