Part 1. Greenhouse gas emissions inventory
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 University of Waterloo uses the following methodology to develop its emissions inventory:
Scope 1:
o Natural Gas: Waterloo calculates natural gas emissions by summing all monthly consumption from invoices for all campuses from fuel service providers, and multiplying the number of total metres cubed of natural gas by the emissions factors listed for Ontario as part of Canada’s annual National Inventory Report to the UNFCCC (1.898311 kgCO2-e per cubic metre of natural gas)
o Fleet fuel: Waterloo calculates fleet fuel use using a total volume of all delivered fuel to the campus from fuel service providers, and multiplying the total number of litres by emissions factors listed as part of Canada’s annual National Inventory Report to the UNFCCC based on fuel type (Diesel = 2.740728 kgCO2-e per litre; Gasoline = 2.316750 kgCO2-e per litre)
Scope 2:
o Electricity: Waterloo calculates electricity emissions by summing all monthly consumption data from invoices for all campuses from local electricity distributors, and multiplying the total electricity consumption by emission factors as listed for Ontario as part of Canada’s annual National Inventory Report to the UNFCCC (0.036 kgCO2-e per kWh). It should be noted that Ontario reports trued emission factors for the period three years previous, and an estimate for the period two years previous. Waterloo extrapolates the estimate (in this case for 2019) onto its annual reporting for the previous year and adjusts as necessary in future years.

A brief description of how the institution accounted for its Scope 3 emissions:
Business travel: Waterloo includes mileage claims paid out for University employees within its emissions calculations. These are calculated using the data collected through Waterloo’s expense claim system and dividing by the designated mileage claim of $0.45 per kilometer. The total annual kilometer rate is then multiplied by emissions factors provided by Sustainable Waterloo Region for an unknown vehicle type (0.21378kgCO2-e per km). Sufficient data to calculate emissions from university-paid airfare is not currently available.
Transmission and Distribution Emissions: Waterloo calculates emissions from transmission and distribution losses by taking the difference between consumption and generation emission factors and multiplying it by total annual energy consumption. As with electricity emissions, Ontario provides an estimate for two years previous, which Waterloo extrapolates onto its performance year (0.00 kgCO2-e per kWh effective 2020)
Waste: Waterloo collects annual tonnage of waste sent to landfill from its waste haulers, and multiplies the total by waste emission factors calculated by the Region of Waterloo based on a previous study of the local landfill. (0.19 kgCO2-e per kilogram of waste)
Commuting: Waterloo collects information on employee and student commuting as part of a biennial travel survey facilitated through the Region of Waterloo TravelWise program. The surveys data, including modeshare, distances to campus, vehicle information, and frequency of travel to campus, is then used to extrapolate a calculation for commuting emissions by various sources – single occupancy vehicle, carpooling, and transit, for example.
