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

Pre-consumer food waste and animal bedding waste is composted in an in-vessel composter and has been operating since 2010. Windrow composting was added in 2018. This expansion and method increased the opportunity to compost post-consumer food waste, mainly from dining centers, but also many collection locations in academic buildings around campus which collect paper towel waste and breakroom food waste. This substantially increased volumes of campus composting operations.


Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 145,858.33 Metric Tons of CO2 Equivalent 176,916.90 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, 2009
End date June 30, 2022 June 30, 2010

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

FY10 is the baseline year that aligns with the year that CSU developed their first Climate Action Plan (CAP) and established a timeline for carbon neutrality. In 2021, CSU adopted a new date for carbon neutrality, 2040, formalized in a 2022 CSU CAP Update. The goal date was moved forward from 2050 established by the first CSU CAP. FY10 remains the baseline year against which CSU measures its progress toward the goal.

Total full-time equivalent student enrollment 29,260 24,304.90
Full-time equivalent of employees 7,008 6,140
Full-time equivalent of students enrolled exclusively in distance education 6,127 2,879
Weighted Campus Users 25,244.50 22,010.18

Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:
Performance year Baseline year
Adjusted net Scope 1 and 2 GHG emissions per weighted campus user 5.78 Metric Tons of CO2 Equivalent 8.04 Metric Tons of CO2 Equivalent

Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:
28.12

Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:

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

CSU wrote and adopted a Climate Action Plan (CAP) in FY10. Since that time total GHG emissions have been reduced by 22%. GHG emissions per GSF are down 41% and GHG emissions per student are down 39%

In January 2017, Colorado State University signed the Climate Reality Pledge – committing the university to 100% renewable electricity by 2030. Since that time, local utilities have also committed to this same goal.

In 2020, CSU installed one of the largest ground source heat pumps in the western US. This system utilizes 342 wells, 550 feet deep to exchange heat with the ground and efficiently provide heating and cooling to the Moby Complex (a 375,000 GSF mixed use athletic facility).
