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.
