Gross Scope 1 GHG emissions from stationary combustion 3,790.72 Metric tons of CO2 equivalent 35,852.50 Metric tons of CO2 equivalent
Gross Scope 1 GHG emissions from other sources 513.19 Metric tons of CO2 equivalent 713 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported electricity 741.97 Metric tons of CO2 equivalent 58,093.10 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported thermal energy 24,171.62 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Total 29,217.50 Metric tons of CO2 equivalent 94,658.60 Metric tons of CO2 equivalent

Carbon sinks

Figures needed to determine net carbon sinks:
Performance year Baseline year
Third-party verified carbon offsets purchased 6,948 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Institution-catalyzed carbon offsets generated 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Carbon storage from on-site composting 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Carbon storage from non-additional sequestration 0 Metric tons of CO2 equivalent ---
Carbon sold or transferred 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Net carbon sinks 6,948 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent

If total performance year carbon sinks are greater than zero, provide:

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

Verified carbon reduction tonnes generated by a landfill gas capture project in Ohio and registered with the Climate Action Reserve (“CAR”) for the vintage year 2008. The site is fueled by landfill gas, produced by decomposing garbage and collected by a series of pipes throughout the landfill for use as a fuel in either a gas engine or gas turbine generators.


Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 22,269.50 Metric tons of CO2 equivalent 94,658.60 Metric tons of CO2 equivalent

Performance and baseline periods

Start and end dates of the performance year and baseline year (or three-year periods):
Performance year Baseline year
Start date July 1, 2023 July 1, 2004
End date June 30, 2024 June 30, 2005

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

Baseline of FY 2005 was adopted after a CACP analysis was done for that year.


Part 1. Reduction in GHG emissions per person

Total full-time equivalent student enrollment 14,156.20 8,803.40
Full-time equivalent of employees 5,350.40 3,978.30
Full-time equivalent of students enrolled exclusively in distance education 438.20 106.50
Weighted Campus Users 15,252.55 10,442.40

Metrics used in scoring for Part 1
