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

Our Rock Creek campus composts over 14,000 pounds of waste every year. Our Sylvania campus composts over 6,000 pounds a year.


Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 9,118.40 Metric tons of CO2 equivalent 22,958 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, 2005
End date June 30, 2019 June 30, 2006

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

2006 is the adopted baseline because that is the year the college adopted its' Sustainability Policy.

Data source(s) and notes about the submission:

The college has seen significant savings in scope 1 emissions due to a large decrease in natural gas consumption since 2006. This is attributed to removing old natural gas boilers and replacing these with more efficient boilers (reduced natural gas consumption by more than 40%), utility loop upgrades and building renovations district-wide.

We changed to a market based emissions model - our baseline does not reflect this model.
