Offsets from Raker and Graver Arboretums approximated using Tree Map application.


Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 15,547.87 Metric tons of CO2 equivalent 18,590.40 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, 2021 July 1, 2007
End date June 30, 2022 June 30, 2008

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

The baseline was adopted as this is the year after we built the first LEED certified building, the Greening Committee was established as significant attention was drawn to our institutional carbon footprint.
