Abstract or Description

In 2013 Colby College declared it was carbon neutral. The college achieved “net zero” CO2 equivalent emissions by switching to wind power for electricity and replacing 90% of its oil consumption with biomass. The remaining emissions were offset based on assumptions about travel, waste, consumption, etc. The goal of this project was to update the estimate of the total greenhouse gas emissions produced as a result of faculty, staff, and students commuting to Colby in 2013. This is not a comprehensive analysis of all college related travel, but a specific subset. This is important because it can improve Colby’s estimate of its emissions, informing the school of the amount of carbon credits it needs to be carbon neutral. GIS was used to calculate travel distances for the various members of the College community. Assumptions about type and frequency of travel method were then used to calculate the total carbon dioxide equivalent emissions in 2013.
