Director of Environmental Health, Safety, and Sustainability
Physical Plant - Facilities
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:
Wesleyan uses SIMAP to calculate its greenhouse gas emissions inventory; the inventory is calculated internally by Wesleyan's Facilities Business Manager.
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:
Documentation to support the GHG inventory verification process:
Gross Scope 1 GHG emissions, performance year:
|Weight in MTCO2e|
|Stationary combustion||19,651 Metric Tons of CO2 Equivalent|
|Other sources (mobile combustion, process emissions, fugitive emissions)||326 Metric Tons of CO2 Equivalent|
Total gross Scope 1 GHG emissions, performance year:
Gross Scope 2 GHG emissions, performance year (market-based):
|Weight in MTCO2e|
|Imported electricity||1,187 Metric Tons of CO2 Equivalent|
|Imported thermal energy||0 Metric Tons of CO2 Equivalent|
Total gross Scope 2 GHG emissions, performance year:
Gross GHG emissions from biogenic sources, performance year:
Does the GHG emissions inventory include Scope 3 emissions from the following sources?:
|Yes or No||Weight in MTCO2e|
|Business travel||Yes||3,681 Metric Tons of CO2 Equivalent|
|Commuting||Yes||1,540 Metric Tons of CO2 Equivalent|
|Purchased goods and services||Yes||112 Metric Tons of CO2 Equivalent|
|Fuel- and energy-related activities not included in Scope 1 or Scope 2||Yes||60 Metric Tons of CO2 Equivalent|
|Waste generated in operations||Yes||0 Metric Tons of CO2 Equivalent|
|Other sources||Yes||1,319 Metric Tons of CO2 Equivalent|
Total Scope 3 GHG emissions, performance year:
A brief description of how the institution accounted for its Scope 3 emissions:
Scope 3 emissions (other) include study abroad (1329 MTCO2e), solid waste (-25 MTCO2e), and wastewater (15 MTCO2e).
Commuting data is based on zip codes.
Employee business travel is extrapolated from spend on air and ground travel.
Study abroad air travel is extrapolated based on country visited (calculate RT emissions to largest city in that country).
Solid waste, wastewater, paper purchasing, and T&D loss emissions are all direct calculations.
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)||18.70 Tons|
|Sulfur oxides (SOx)||0.85 Tons|
|Carbon monoxide (CO)||11.37 Tons|
|Particulate matter (PM)||4.16 Tons|
|Ozone (O3)||0 Tons|
|Lead (Pb)||0.00 Tons|
|Hazardous air pollutants (HAPs)||0.22 Tons|
|Ozone-depleting compounds (ODCs)||0.00 Tons|
|Other standard categories of air emissions identified in permits and/or regulations||2.64 Tons|
Do the air pollutant emissions figures provided include the following sources?:
|Yes or No|
|Major stationary sources||Yes|
|Off-site electricity production||No|
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
Wesleyan has inventoried every piece of fossil fuel burning equipment on campus. Equipment is grouped based on its capacity and type of fuel and emissions calculations, following EPA prescribed processes. These processes are performed for each group of equipment. Emissions calculations are maintained on a rolling 12 month period. The data above is from the most recent year collected, ending in September 2017.
For stationary air emissions, we do not record ozone as a pollutant. PM includes PM 2.5 and PM 10. HAPs include benzene, dichlorobenzene, formaldehyde, hexane, naphthalene, toluene, ethyl benzene, xylene, acrolein, methanol, and styrene. The only ODC Wesleyan includes in its air inventory is carbon tetrachloride. Our "other" category is VOCs (0.82 tons). The data represented for stationary sources is for calendar year 2015.
