A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):

Williams College purchases offsets after the end of our fiscal year in order to neutralize the college's operational emissions from that fiscal year. For this submission, we purchased offsets to neutralize the FY21 emissions (July 1, 2020-June 30, 2021) in the fall of 2021 and have retired them.

Information about Williams College's offset purchases can be found here:

Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 0 Metric tons of CO2 equivalent 29,574 Metric tons of CO2 equivalent

Start and end dates of the performance year and baseline year (or three-year periods):
Performance year Baseline year
Start date July 1, 2020 July 1, 2004
End date June 30, 2021 June 30, 2005

A brief description of when and why the GHG emissions baseline was adopted:

We adopted FY2005 as our baseline for this STARS report because it's the year before the college's first GHG emissions goal was set.

A brief description of the institution’s GHG emissions reduction initiatives:

Williams actively invests in energy conservation and efficiency projects in campus buildings. We invested in the Farmington Solar Project and purchased RECs to zero out our scope two emissions.
