The document summarizes the U.S. Department of Energy's sustainability performance in fiscal year 2012. It reports that DOE met or exceeded goals for reducing greenhouse gas emissions, energy intensity, water use, and increasing use of renewable energy and green buildings. However, it did not meet the goal for reducing fleet petroleum use. Going forward, DOE aims to increase renewable energy goals, adapt to climate change, use more performance contracting, and improve building sustainability through data-driven measures.
