Colby’s Emissions at a GlanceIMG_20140422_122226

Colby declared Carbon Neutrality in 2013. A number of campus initiatives contributed to this effort including Colby’s move to 100-percent renewable electricity sources in 2003, pursuing LEED certification in all new construction projects, retrofitting energy-intensive components of existing buildings and other fixtures with more efficient ones, using cogeneration to produce 10 percent of our electricity from the biomass plant, and purchasing carbon offsets through projects across Maine. Learn More >

In 2011 Colby opened a biomass plant that has state-of-the-art emission reduction technologies (such as an electrostatic precipitator), which supplies 90 percent of the College’s steam and 10 percent of our electricity. It offsets the use of more than one million gallons of residual oil a year with about 22 thousand tons of low-grade forest waste and debris from sustainable forest operations within roughly a 50-mile radius of campus.  Fact Sheet >>

Carbon Offsets

In 2013, Colby announced carbon neutrality. In order to identify potential carbon offset projects, Colby relied on a senior thesis project that identified four major criteria in order to compare offset projects. The criteria included initial components of project type and their cost, but also included the following: third-party certification, regionality, additionality or the concept of supporting projects that create additional carbon offsets, and public relations. Since 2013, Colby has identified and supported carbon offset projects local to New England, and will continue to do so each year.
