With the issuance of Executive Order 13514 on federal sustainability, the Obama administration has called upon the federal government to lead by example: making its operations more sustainable, responsible, and efficient. “As the largest consumer of energy in the U.S. economy, the federal government can and should lead by example when it comes to creating innovative ways to reduce greenhouse gas emissions, increase energy efficiency, conserve water, reduce waste, and use environmentally responsible products and technologies,” said President Obama. “This Executive Order builds on the momentum of the Recovery Act to help create a clean energy economy and demonstrates the federal government’s commitment, over and above what is already being done, to reducing emissions and saving money.” We spoke with the Federal Environmental Executive Michelle Moore about efforts to implement the requirements of E.O.13514, pursuing the GreenGov challenge, working with federal agencies on sustainability plans, and other innovative approaches to greening federal government operations.
