Guests travel both internationally and from all over the United States to see graduation.  They arrive from planes, cars, and buses that contribute carbon emissions to the atmosphere.  At a traditional graduation, these carbon emissions would be environmental externalities that are not included in the costs of the ceremony.  Using zip code data, Manny Gimond, the Environmental Studies Department GIS and Quantitative Analysis Specialist, created a model using ArcGIS to determine the kilometers people travel by car and by plane to arrive at Colby.  A map of the costs to offset these emissions will be provided at the centrally located education booths during the Green Graduation.  Guests will receive information about how to offset their personal emissions to help contribute to Colby’s environmental efforts.
