Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 126,426.50 Metric Tons of CO2 Equivalent 176,911 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, 2018 July 1, 2003
End date June 30, 2019 June 30, 2004

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

FY2004 was selected as the baseline year because UMass reports annually to the MA DOER Leading by Example Program which uses Executive Order 484 goals and 2004 baseline year as a benchmark for tracking progress.

Additional documentation to support the submission:

The drastic reduction in imported electricity emissions is due to the reduction in imported electricity from baseline year. The amount of kWh imported in baseline year (FY04) was over 113 million. The performance year (FY19) kWh imported was 48 million. UMass has increased on-site electricity production via the Central Heating Co-Gen Plant and on-site solar energy allowing for much less imported grid electricity. The ISO-NE grid emissions factor has also become significantly greener and less carbon intensive over this time.
