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:

UMD used the SIMAP calculator to find Scope 1 and 2 emissions for FY2022. The inventory includes Scope 1 (on campus stationary sources, fleet, refrigerants, and fertilizers), Scope 2 (purchased electricity), and Scope 3 (estimated faculty and student commuting, air travel, and solid waste). Input data is gathered by the Office of Sustainability annually from data custodians across the institution and then enters that information into SIMAP. We follow an operational control approach from the GHG Protocol (https://ghgprotocol.org/).


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:

Scope 1 GHG emissions
Gross Scope 1 GHG emissions, performance year:
Weight in MTCO2e
Stationary combustion 18,504 Metric tons of CO2 equivalent
Other sources (mobile combustion, process emissions, fugitive emissions) 609 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:
19,113 Metric tons of CO2 equivalent

Scope 2 GHG emissions
Gross Scope 2 GHG emissions, performance year (market-based):
Weight in MTCO2e
Imported electricity 18,159 Metric tons of CO2 equivalent
Imported thermal energy 0 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:
18,159 Metric tons of CO2 equivalent

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

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 1,236 Metric tons of CO2 equivalent
Commuting Yes 2,476 Metric tons of CO2 equivalent
Purchased goods and services No 0 Metric tons of CO2 equivalent
Capital goods No ---
Fuel- and energy-related activities not included in Scope 1 or Scope 2 No ---
Waste generated in operations Yes 258 Metric tons of CO2 equivalent
Other sources Yes 39 Metric tons of CO2 equivalent

Total Scope 3 GHG emissions, performance year:
4,009 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:

We use air travel spend data provided by the University's Purchasing Department. That spend data is entered directly into SIMAP which calculates emissions associated with travel based on estimated emissions per $ of travel spend. For commuting, we obtain anonymized address data and use ArcGIS to calculate average travel distances from residence to campus. Bus pass sales data and distance traveled are used to develop estimated mode share split. This combined with assumptions on assumed trip frequency is entered into SIMAP to calculate estimated emissions attributable to commuting. Waste data is collected from bills, either exact tonnage direct from bills or assumed tonnage based on receptacle size and EPA conversion rate for tonnage per cubic yard of MSW.


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) 16.43 Tons
Sulfur oxides (SOx) 0.63 Tons
Carbon monoxide (CO) 13.85 Tons
Particulate matter (PM) 0.13 Tons
Ozone (O3) 0 Tons
Lead (Pb) 0.09 Tons
Hazardous air pollutants (HAPs) ---
Ozone-depleting compounds (ODCs) ---
Other standard categories of air emissions identified in permits and/or regulations ---

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:

Emissions are calcuated using emission factors (USEPA published & peformance test based) along with monitored fuel throughput/equipment runtime data
