Bowdoin College says the school has become entirely carbon neutral, meaning the school has a net zero carbon footprint.
The announcementcomes two years ahead of the school's goal to reduce its net carbon dioxide emissions to zero.
The Lewiston Sun Journal reports College of the Atlantic in Bar Harbor and Colby College have already achieved that goal. Bates is set to follow suit.
The project was spawned as part of the American College & University Presidents’ Climate Commitment agreement that hundreds of colleges and universities entered into in 2007.
The agreement set a goal for schools to reach carbon neutrality by 2020.
