In 2005 Yale committed to a greenhouse gas emissions reduction goal of 43% below 2005 levels by 2020. To achieve this goal, the University has committed to reducing energy use within buildings through conservation and efficiency, adhering to sustainable construction and renovation standards for buildings, increasing efficiency in Yale’s on-campus power plants, and promoting behavioral shifts by building occupants.

In 2016 energy usage decreased 16.8% from 2013. Yale decreased its GHG emissions by 8.7% from 2013 levels. This is a 23.6% decrease from our 2005 baseline year.
