Summary: CEAC’s goal this year was not to issue recommendations for offset purchasing, but to gather information and explore competing viewpoints with an eye toward developing an offsets policy for the 2020 goal and beyond. The Committee disagreed on many questions about offsetting, sometimes quite strongly. Two things we did not disagree on were the need to engage in a more vigorous public conversation about carbon offsets at Williams, and the need to link offsets to our educational mission.
