Huge congratulations to Colby College for becoming just the fourth college in the United States to achieve full carbon-neutrality. Colby College, located in Waterville, Maine, (not too far from me here in Portland), didn't entirely cut its carbon dioxide emissions, but rather greatly reduced its emissions and bought offsets for the portion school officials were unable to eliminate.

In 2002, each Colby student was responsible for around 15.6 tons of carbon dioxide. In 2012, the rate had been reduced to 5.72 tons per student and stands at 3.87 tons per student today. That's a remarkable reduction. The national average is around 9 tons per student.

Colby had set a goal of reaching carbon neutrality by 2015 but hit the mark two years early, thanks in part to the installation of a large biomass heating plant that services campus buildings. School officials also installed a co-generation turbine that produces electricity using waste heat and hot water from campus, and the campus buys almost all of its electricity from renewable sources.
