2008 U.S. Fossil Fuel CO2 Emissions See Biggest Drop in Nearly 30 Years

New auto standards: the start of Obama’s green revolution

President Obama’s announcement on tailpipe emissions Tuesday reaffirmed a commitment that goes beyond regulation of the auto industry. The move is part of a broader White House strategy to confront the risk of global warming while making green-collar jobs a centerpiece of the economy. For ordinary Americans, the resulting changes could be far-reaching. Lighter-weight vehicles appear likely to become more popular. More tax dollars are being tabbed for clean-energy technology. And for years to come, college students might find that some of the hottest job opportunities lie in helping to keep the planet cool.
