UC Berkeley has reduced its carbon footprint to 1990 levels -- a goal it reached two years early, according to a new energy analysis of 2012 greenhouse gas emissions released Tuesday.
The campus installed more energy efficient buildings and lights, and students and faculty helped out by biking or taking public transit more often, cutting commute fuel use by 55 percent.
Students also waged energy-saving Blackout Battles between residence halls and, along with faculty and other staffers, participated in the Cal Climate Action Partnership formed in 2006.
The UC Sustainable Practices Policy guidelines and the state's Global Warming Solutions Act of 2006 set 2020 as the deadline; a more aggressive campus goal was to reach this point by 2014.
Berkeley's Chancellor Nicholas Dirks said the campus will keep on going until it neutralizes its emissions.
"Climate change is an existential global threat and one that the UC Berkeley community is continually addressing through campus practices, teaching, research and public service," he said.
