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:
Various methodologies were employed to calculate the emissions related to various scopes.
SCOPE 1 emissions were calculated using the Government of Canada's Greenhouse Gas Quantification Methodology.

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:
An audit was conducted on our scope 1 and 2 emissions by Internat in 2016 and 2017, as required by the Ontario Provincial government.
In 2019, the University of Ottawa hired an energy analyst, separate from our energy manager, to verify finances related to utilities. The Energy Analyst uses bills from our utility providers to verify consumption rates and emissions.

A brief description of how the institution accounted for its Scope 3 emissions:
Scope 3 emissions were calculated using different methods.
Investment emissions were provided by the University of Ottawa's Pension fund manager. Index data is difficult to interpret because carbon
footprint calculations are based on index composition and
weighted by market pricing.
Commuting emissions - Commuting data is collected every three years and emissions are calculated based on the average distance travelled for each modality.
Waste management emissions - Emissions associated with waste and recycling were calculated using waste audit data to determine weights, and emissions factors were applied by category.
Business travel - Calculated using procurement data from across the campus. Costs were converted to passenger mile traveled (Carbonfund.org). Estimates remain incomplete because they do not account for all travel, they do not differentiate travel class, and they do not account for layovers.

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
We do have an inventory of all our air emission sources but do not take any readings at the sources themselves. The air and noise modelling requirements for our emission approvals are based on input from maximum operating parameters, equipment specifications and worst-case scenarios. The internal operational procedures, maintenance programs on critical equipment ensure they work as specified and therefore modelling parameters are respected and we do not exceed the maximum allowed by the regulations.
- Our Stand-By generators are inventoried and registered under the EASR system of Ontario and meet the MOECC air emission standards.
- All our other stationary sources (boilers, fumehoods, HVAC systems) are inventoried. And they are approved by the MOECC under the ECA approval system for their respective Facilities.
