Henry Waxman (D-CA) is drilling down on federal agencies to show Congress how they are acting to meet a variety of laws and executive orders aimed at making them energy efficient and reducing their carbon footprints. Waxman and Sen. Sheldon Whitehouse (D-RI) sent joint letters Feb. 25 to the inspectors general at 70 federal agencies asking for progress reports. Their letters came after the Government Accountability Office earlier this month placed climate change on its high risk list, connoting it now presents a significant financial risk to the federal government. Among the steps federal agencies are supposed to be taking are to cut energy use in their buildings 30 percent by 2015 and reduce petroleum use in their vehicle fleets 30 percent by 2020. They also are to specify sustainability criteria for contractors.
