Harvard has committed to reduce its greenhouse gas emissions by 30% below a 2006 baseline by 2016, inclusive of growth. As of the end of Fiscal Year 2008 emissions have decreased 5% including growth, 8% without growth (from base buildings).
Harvard University adopted Green Building Guidelines in 2007 that require LEED Silver minimum plus additional requirements. As of October 2009 Harvard has 71 buildings registered with the United States Green Building Council (USGBC), 23 of which are certified, the highest number of certified projects of any U.S. university according to the USGBC. Given that buildings account for such a large percentage of energy used in the U.S., high-performance, energy-efficient buildings are a major part of reducing Harvard's greenhouse gas emissions.
