Data source(s) and notes about the submission:

The use of 2005 as the STARS baseline year for assessing greenhouse gas emissions reductions gives an inaccurate measurement of Colby’s positive actions taken to reduce greenhouse gas emissions and effectively penalizes Colby for being an early leader in the movement to buy green electricity. In 2003, Colby changed to 100 percent clean renewable sources for its electricity, a move so groundbreaking that it helped establish a market for green power in the state of Maine and led to national recognition for its green electricity use. In 2002, Colby’s emissions from electricity sources were 32% of its total calculated greenhouse gas emissions. Colby’s greenhouse gas emissions reductions are more accurately reflected when 2002 is used as the baseline year for the STARS analysis. The data for 2002 are outlined below:

Scope 1 & 2 gross GHG emissions, MT CO2e:21,461
Third-party verified carbon offsets purchased, MT CO2e
On campus residents 1825
Full-time commuter students, faculty, staff 667
Part-time commuter students, faculty, staff 163

This computes as 6.10/14 points
