Part 1. Greenhouse gas emissions inventory

Has the institution conducted a GHG emissions inventory within the previous three years that includes all Scope 1 and 2 emissions? :
Yes

A copy of the most recent GHG emissions inventory:
A brief description of the methodology and/or tool used to complete the GHG emissions inventory:
The University of Houston utilized the Sustainability Indicator Management and Analysis Platform (SIMAP) from the UNH Sustainability Institute tool to calculate greenhouse gas emissions. The platform was based on the workbooks provided by the Intergovernmental Panel on Climate Change (IPCC) for national-level inventories, and it incorporates data from the Fourth Assessment Report of the IPCC. SIMAP has adapted this IPCC data for use at institutions like a college or university, but follows the same protocols.

Scope 3 emissions data was collected through different departments on campus:
-Commuting through Parking and Transportation (collected number of parking permits and by survey results estimated average distance). (NOTE: Parking and Transportation did not provide data for 2023, so commuting activity for 2021 is included in this emissions report as a proxy.)
-Air travel through Study Abroad Office (collected number of students who traveled abroad and their locations).
-Waste and water through UH Facilities

Has the GHG emissions inventory been validated internally by personnel who are independent of the GHG accounting and reporting process and/or verified by an independent, external third party?:
No

A brief description of the GHG inventory verification process:

Total gross Scope 2 GHG emissions, performance year:
105,165.62 Metric tons of CO2 equivalent

GHG emissions from biomass combustion
Gross GHG emissions from biogenic sources, performance year:

A brief description of how the institution accounted for its Scope 3 emissions:
Data was collected directly from Parking and Transportation, study abroad, and facilities services and then entered into the SIMAP Carbon Calculation tool.
