Has the institution conducted a GHG emissions inventory within the previous three years that includes all Scope 1 and 2 emissions? :
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 data collection for the Ohio State's Carbon Footprint is carried out by employees in the Sustainability Office within FOD. Various departments are contacted to request records of data relevant to the Carbon Footprint Inventory.
The Sustainability Indicator Management & Analysis Platform (SIMAP) is used to format the data and calculate the equivalent CO2 emissions from each of the inventoried sources. SIMAP is updated each year with new emission coefficients and trending equations. The version used for the FY 2021 Ohio State Carbon Footprint Inventory utilized emission factors from SIMAP's 2021 database.
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?:
A brief description of the GHG inventory verification process:
Ohio State’s Office Administration and Planning Metrics group completes the internal independently-validated process for the GHG inventory prior to submission.
In addition to utilizing the Sustainability Indicator & Management Analysis Platform (SIMAP) for internal verification and reporting, The Ohio State University also reports this data annually to Second Nature, to the ACUPCC, and other 3rd-Party organizations.

A brief description of how the institution accounted for its Scope 3 emissions:
Has the institution completed an inventory within the previous three years to quantify its air pollutant emissions?:
Annual weight of emissions for::
| Weight of Emissions | |
| Nitrogen oxides (NOx) | 29.53 Tons |
| Sulfur oxides (SOx) | 0.68 Tons |
| Carbon monoxide (CO) | 51.42 Tons |
| Particulate matter (PM) | 5.83 Tons |
| Ozone (O3) | --- |
| Lead (Pb) | 0 Tons |
| Hazardous air pollutants (HAPs) | 2.12 Tons |
| Ozone-depleting compounds (ODCs) | 156,819 Tons |
| Other standard categories of air emissions identified in permits and/or regulations | 4.63 Tons |
Do the air pollutant emissions figures provided include the following sources?:
| Yes or No | |
| Major stationary sources | Yes |
| Area sources | Yes |
| Mobile sources | No |
| Commuting | No |
| Off-site electricity production | No |
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
The University complies with applicable regulations and follows the terms of its Title V operating permit and regulations for air emissions monitoring, calculations, reporting requirements. Criteria Pollutants (NOx, SO2, CO, Pb, PM, VOCs) and HAPs are calculated annually for required Ohio EPA emission fee reporting using US EPA AP-42 and other accepted emission factors. CO2e is calculated per the GHG Reporting rule 40 CFR 98, using US EPA GHG emission factors for carbon dioxide (CO2), methane (CH4), and Nitrous Oxide (N2O), which are all converted to CO2e. Total CO2e emissions excludes mobile emission units, emergency generator emissions, and research and development activities as per 40 CFR 98.
