To measure greenhouse gas emissions, Colby uses the Cool Air-Clean Planet (CA-CP) Campus Carbon Calculator, which is recommended by the American College and University Presidents’ Climate Commitment (ACUPCC) because it was designed specifically for college and university campuses.

Colby also engaged a consultant in 2012-13 to conduct an independent analysis of the College’s greenhouse gas emissions. Using its carbon tracker model, Competitive Energy Services of Portland, Maine, performed separate calculations of Colby’s emissions and the results were within one percent of those generated by the CA-CP calculator.

Here is a copy of our most recent calculations from fiscal year 2014-2015:
