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

Connecticut College has a 25-year contract with Reforest the Tropics for a 40-acre carbon offset forest in Costa Rica. The most recent report found an average of 307 MTCO2e was sequestered since the planting. The contract was signed in 1999.

Start and end dates of the performance year and baseline year (or three-year periods):
Performance year Baseline year
Start date July 1, 2016 July 1, 2004
End date June 30, 2017 June 30, 2005

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

We adopted 2005 as our baseline year for GHG emissions reductions to align with the baseline year set in the Paris Climate Agreement. This baseline was adopted alongside the adoption of our Campus Sustainability Plan in 2018. We now have a campus goal to reduce our emissions by 40% from 2005 levels by 2030.

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

In Fall 2019 the College installed a natural gas fuel cell to provide approximately 80% of the main campus meter electricity use. This accounts for the large shift away from Scope 2 emissions. Since 2005 the College switched from fuel oil to natural gas in our steam plant, which significantly reduced emissions. We have also done lighting upgrades, kitchen ventilation improvements, and other energy efficiency projects to reduce emissions.

We recognize that the data for this credit has been strongly impacted by the campus closure in mid-March 2020 due to the Covid-19 pandemic. We have decided to report on FY2020 for all of our credits to maintain consistency in reporting. We were forecasting a decline in emissions prior to the closure (due to the installation of a fuel cell, a small reduction in buildings, and other efficiency programs), but we did have 3 months of less campus usage than would be typical in this fiscal year. To help compensate, we reported a weighted average of students resident on site. See note below for more details.

The number of students resident onsite for our performance year (FY2020) was modified to take into account the campus closure on March 15 due to Covid 19. A weighted average was calculated assuming we had 1,699 students onsite for 29 weeks (August 26-March 15) and 50 students onsite for 11 weeks (March 15-May 30).
