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:

GHG_Inventory_Northwestern__STARS_2020.pdf

A brief description of the methodology and/or tool used to complete the GHG emissions inventory:

GHG inventory developed using SIMAP, which utilizes the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD) GHG Protocol

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?:

Yes

A brief description of the GHG inventory verification process:

Northwestern’s recently hired Director of Sustainability, who has 10+ years of GHG verification experience, was not involved in the FY12-19 GHG inventories. A cross-check review of underlying source data, data inputs, assumptions, emission factors and calculations were performed to ensure reporting accuracy to a limited level of assurance and 5% materiality threshold.

Documentation to support the GHG inventory verification process:

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

Emissions from business air travel estimated using mileage totals provided by travel agency

Emission from business auto travel estimated using mileage totals from expense reports

Emission from commuting estimated using 2018 transportation survey

Emission from inter-campus charter estimated using diesel purchase records and shuttle average fuel economy

Emissions from waste generated in operations estimated using annual waste vendor and wastewater discharge reports

Emissions from purchased goods and services estimated using paper purchase records

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)	180.92 Tons
Sulfur oxides (SOx)	1.11 Tons
Carbon monoxide (CO)	61.29 Tons
Particulate matter (PM)	5.62 Tons
Ozone (O3)	0 Tons
Lead (Pb)	0.00 Tons

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:

Northwestern is required to complete an inventory of all air emissions in coordination with the Illinois EPA's regulations.
