Federal Buildings: Energy Efficiency Management

Last updated: 5 November 2017
In June 1999, the President issued Executive Order 13123 requiring each Federal agency to improve energy efficiency by 35% percent below 1985 levels by 2010 in its buildings and by 25% (relative to 1990) in its laboratories. This will reduce annual GHG emissions by 2.4 million tonnes of carbon equivalent with savings of more than USD 750 million a year. The President further required each federal agency to cut greenhouse gas emissions by 30 percent relative to 1990 levels by 2010.
