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

The four-star Green Restaurant dining hall Cougar Woods started composting all back-of house food waste through a third-party provider, Zero Waste Houston. In Fiscal Year 23 alone, over 220,000 pounds of food waste was diverted from the landfill.


Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 132,680.60 Metric tons of CO2 equivalent 132,117.40 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 Sept. 1, 2022 Sept. 1, 2008
End date Aug. 31, 2023 Aug. 31, 2009

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

We chose fiscal year 2009 as our baseline year as this was our most accurately assessed analysis of the university's greenhouse gas emissions prior to the performance year.


Figures needed to determine “Weighted Campus Users”:

Number of students resident on-site 6,878 4,950
Number of employees resident on-site 0 0
Number of other individuals resident on-site 0 0
Total full-time equivalent student enrollment 37,837 29,630
Full-time equivalent of employees 5,215 4,623
Full-time equivalent of students enrolled exclusively in distance education 2,200 893
Weighted Campus Users 32,358.50 26,257.50

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 4.10 Metric tons of CO2 equivalent 5.03 Metric tons of CO2 equivalent

Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:
18.51

Gross floor area of building space, performance year:
16,740,264 Gross square feet

Floor area of energy intensive building space, performance year:

Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:
0.01 MtCO2e per square foot

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

UH has various initiatives that impact the reduction of Green House Gasses. At the top level, all buildings are required to be LEED silver certified or above. Facilities Planning is also rolling our an Energy Master Plan in addition to maintaining a campus tree inventory to ensure proper mitigation of any canopy loss. And, the dining halls have begun recycling programs and are composting all back-of-house food waste.
