"President Barack Obama is putting the federal government on a greenhouse-gas diet. In an executive order signed Monday, Obama directed all agencies to set the first-ever targets for reducing climate-altering pollution from government buildings, fleets and federal workers' commutes. The agencies will have 90 days to tell the White House how much they plan to measure and reduce greenhouse gases from buildings and vehicles by 2020. Targets for employees' commutes and travel will be due June 2010." Dina Cappiello reports for the Associated Press October 6, 2009.
