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 UNH SIMAP system was used to calculate both the baseline FY2017 emissions and the FY2023 emissions. A Market-Based method was used for Scope 2 reporting. Data was provided by Facilities Operations and unit conversions were completed using a provided template.

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:
While we do not have a process for a systemic review of our data, the raw data and results are reviewed by a faculty member and the results are shared with the Environmental Model Committee annually.

Documentation to support the GHG inventory verification process:
---

Scope 1 GHG emissions
Gross Scope 1 GHG emissions, performance year:
Weight in MTCO2e
Stationary combustion 8,837.28 Metric tons of CO2 equivalent
Other sources (mobile combustion, process emissions, fugitive emissions) 174.51 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:
9,011.79 Metric tons of CO2 equivalent

Scope 2 GHG emissions
Gross Scope 2 GHG emissions, performance year (market-based):
Weight in MTCO2e
Imported electricity 1,559.34 Metric tons of CO2 equivalent
Imported thermal energy 0 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:
1,559.34 Metric tons of CO2 equivalent

GHG emissions from biomass combustion
Gross GHG emissions from biogenic sources, performance year:
0 Metric tons of CO2 equivalent

Scope 3 GHG emissions
Does the GHG emissions inventory include Scope 3 emissions from the following sources?:
Yes or No Weight in MTCO2e
Business travel Yes 452.06 Metric tons of CO2 equivalent
Commuting Yes 1,080.43 Metric tons of CO2 equivalent
Purchased goods and services No ---
Capital goods No ---
Fuel- and energy-related activities not included in Scope 1 or Scope 2 Yes 3,628.79 Metric tons of CO2 equivalent
Waste generated in operations Yes 2.85 Metric tons of CO2 equivalent
Other sources Yes 507.38 Metric tons of CO2 equivalent

Total Scope 3 GHG emissions, performance year:
5,671.51 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:
Business travel mileage was compiled from our consolidated travel booking platform and includes air and train mileage.

Commuting mode and mileage data was collected through a survey of faculty, staff and students in fall 2022.

Fuel and Energy Related Activities includes transmission and distribution losses and the new upstream emissions category (extraction, production and transportation) calculated automatically by SIMAP.

Solid waste was calculated based on the weight of trash sent to a mass burn incinerator.

Study abroad emissions (reported above as "Other") were calculated based on estimated round-trip flight miles taken by students to 35 different study abroad locations.

Part 2. Air pollutant emissions inventory

Has the institution completed an inventory within the previous three years to quantify its air pollutant emissions?:
Yes

Annual weight of emissions for::
Weight of Emissions
Nitrogen oxides (NOx) 3.73 Metric tons
Sulfur oxides (SOx) 0.77 Metric tons
Carbon monoxide (CO) 2.88 Metric tons
Particulate matter (PM) 0.49 Metric tons
Ozone (O3) 0 Metric tons
Lead (Pb) 0 Metric tons
Hazardous air pollutants (HAPs) 0 Metric tons
Ozone-depleting compounds (ODCs) 0 Metric tons
Other standard categories of air emissions identified in permits and/or regulations 0.26 Metric 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

None
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
A third-party consultant conducts an annual air emissions inventory as required by the Connecticut Department of Energy and Environmental Protection for our GPLPE (General Permit to Limit Potential to Emit) Annual Compliance Certificate.
