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 Sustainability Indicator Management and Analysis Platform (SIMAP) was used to compute GHG emissions for all Scope 1, 2, and 3 sources again this year.

Scope 1 emissions were determined by collecting necessary data from appropriate university offices.

Scope 2 emissions were determined solely from purchased electricity data.

Scope 3 emissions from the following sources were determined as described:
1) Faculty and student commuting was calculated by obtaining self-reported student/faculty commuting data from the Fall 2021 commuter survey.
2) Directly financed travel was calculated by the number of dollars spent for flights and mile numbers for reimbursed mileage.
3) Study abroad travel was calculated using the estimated distance of the flights for each study abroad trip taken within the reporting period.
4) Solid waste data was collected from appropriate university offices.
5) Wastewater was computed from the amount of potable water used minus the difference between the metered amount of water entering evaporative cooling towers and not returning from the cooling towers to the sewer system.
6) Paper purchasing data was acquired from appropriate university offices and then broken down by paper type.
7) T&D losses were calculated using the scope 2 purchased electricity data.

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:
An internal Facilities Services Utilities and Engineering staff member, who is independent of the GHG accounting and reporting process, has reviewed and validated the GHG emissions inventory, as have several members of the Lehigh Sustainablity Council.

Documentation to support the GHG inventory verification process:

Gross Scope 1 GHG emissions, performance year:
Weight in MTCO2e
Stationary combustion 21,193.98 Metric tons of CO2 equivalent
Other sources (mobile combustion, process emissions, fugitive emissions) 1,407.86 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:
22,601.84 Metric tons of CO2 equivalent

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

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

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

Does the GHG emissions inventory include Scope 3 emissions from the following sources?:
Yes or No Weight in MTCO2e
Business travel Yes 6,289.93 Metric tons of CO2 equivalent
Commuting Yes 5,833.73 Metric tons of CO2 equivalent
Purchased goods and services Yes 58.13 Metric tons of CO2 equivalent
Capital goods No ---
Fuel- and energy-related activities not included in Scope 1 or Scope 2 Yes 1,596.59 Metric tons of CO2 equivalent
Waste generated in operations Yes 0 Metric tons of CO2 equivalent
Other sources Yes 1,872.72 Metric tons of CO2 equivalent

Total Scope 3 GHG emissions, performance year:
15,651.10 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:
Scope 3 -
1) Business travel includes air travel and personal mileage reimbursement only.
2) Commuting includes both student/faculty daily travel to campus.
3) Purchased goods and services is only paper purchasing.
4) Fuel and energy related activities category includes T&D Losses.
5) Waste generated in operations contains solid waste and wastewater. It is listed as zero because our solid waste is burned and converted into energy therefore offsets any emissions of the waste or wastewater.
6) Other sources includes study abroad air travel.

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) 17.38 Tons
Sulfur oxides (SOx) 0.18 Tons
Carbon monoxide (CO) 37.44 Tons
Particulate matter (PM) 1.93 Tons
Ozone (O3) 0 Tons
Lead (Pb) 0 Tons
Hazardous air pollutants (HAPs) 0 Tons
Ozone-depleting compounds (ODCs) 0 Tons
Other standard categories of air emissions identified in permits and/or regulations 3.64 Tons

Do the air pollutant emissions figures provided include the following sources?:
Yes or No
Major stationary sources Yes
Area sources No
Mobile sources Yes
Commuting Yes
Off-site electricity production Yes

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
Multiple calculation methodologies were used that are specific to each source of emissions.

The University's Air Emissions Permit issued by the Pennsylvania Department of Environmental protection (PADEP) requires the University to compute its emissions from regulated stationary sources on a calendar year basis. The calculations shown above were computed on a fiscal year basis (to match the performance year reported to STARS), in the same manner as the annual calendar year emissions report filed with PADEP.

Mobile sources and commuting air pollutants were modeled using the Argonne National Laboratory's AFLEET Tool, 2019. The Alternative Fuel Life-Cycle Environmental and Economic Transportation (AFLEET) Tool uses the Environmental Protection Agency's Motor Vehicle Emissions Simulator (MOVES) data to develop models for tailpipe air pollution emissions.

The figure reported above for the "other" category is VOC emissions.

Data source(s) and notes about the submission:
Emissions were impacted by COVID-19. To represent a normal year, we used data from FY 19 for electricity, with reductions from a renewable energy purchase from a virtual power purchase agreement (68,738,657.53 kWh of RECs) that occurred starting February 2020 in reporting for Scope 2. We are assuming that energy consumption and emissions would have been fairly consistent both years, with the exception of the renewable energy purchase component. Scope 1 and Scope 3 emissions are entirely representative of FY 19.

For Part 2, FY 19 data was reported for stationary sources to represent a normal year; however, air pollution data for commuting and mobile sources was updated for FY 21 using newer, more accurate and representative data from the Commuting Survey sent out in Fall 2021.

[The RECs for Lehigh began accruing on February 20, 2020. By December 31, 2020 Lehigh had accrued a total of 57,847,000 kWh of RECs. Last year, 22,333,000 kWh of RECs were reported to SIMAP, accrued from February 20, 2020 through June 30, 2020. The remaining RECs are accounted for in this report, accruing between July 1, 2020 and December 31, 2020 to comply with the reporting period. Subtracting the RECs reported last year from the total accrued yields 35,514,000 kWh of RECs for this reporting period. In addition, Lehigh received 67,000,000 kWh of RECs for calendar year 2021, so the approximate RECs/day earned from this settlement were calculated and summed for the remainder of the reporting period (January 1, 2021 - June 30,2021). This yielded 33,224,660 kwh of RECs, for a total of 68,738,657.53 kWh of RECs for the reporting period.]
