The authors performed this review to evaluate the U.S. Environmental Protection Agency's (EPA's) progress toward meeting the requirements of Executive Order 13514, 'Federal Leadership in Environmental, Energy, and Economic Performance.' Specifically, they sought to determine EPA's status in planning and measuring reductions of its greenhouse gas (GHG) emissions at Agency facilities. On October 5, 2009, President Obama signed Executive Order 13514 to establish an integrated strategy toward sustainability in the federal government. The executive order introduced new GHG emissions management requirements. It also prioritized the reduction of GHG emissions for all federal agencies and required them to measure, report, and reduce their GHG emissions.
