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 ÉTS GHG emissions inventory was completed for the 2018-2019 fiscal year. It was produced and published in 2020. The methodology used is the Greenhouse Gas Protocol: GHG Protocol Corporate Standard Revised.


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:

The GHG emissions inventory was conducted by a research associate and was supervised and verified by Annie Levasseur, a professor in the Department of Construction Engineering and holder of the Canada Research Chair on Measuring the Impact of Human Activities on Climate Change. Professor Levasseur is a world expert in measuring the impact of climate change. It was reviewed internally by the Sustainable Development Team and in part by the Real Estate Asset Management Department.

Documentation to support the GHG inventory verification process:

Gross Scope 1 GHG emissions, performance year:
Weight in MTCO2e
Stationary combustion 54 Metric Tons of CO2 Equivalent
Other sources (mobile combustion, process emissions, fugitive emissions) 289 Metric Tons of CO2 Equivalent

Total gross Scope 1 GHG emissions, performance year:
343 Metric Tons of CO2 Equivalent

Gross Scope 2 GHG emissions, performance year (market-based):
Weight in MTCO2e
Imported electricity 56 Metric Tons of CO2 Equivalent
Imported thermal energy 1,600 Metric Tons of CO2 Equivalent

Total gross Scope 2 GHG emissions, performance year:
1,656 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 No ---
Commuting Yes 5,566 Metric Tons of CO2 Equivalent
Purchased goods and services No ---
Capital goods No ---
Fuel- and energy-related activities not included in Scope 1 or Scope 2 No ---
Waste generated in operations No ---
Other sources No ---

Total Scope 3 GHG emissions, performance year:
5,566 Metric Tons of CO2 Equivalent

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

A master's student in environmental engineering, supervised by Professor Annie Levasseur, conducted a large project to calculate emissions from commuting. The project estimated the greenhouse gas emissions generated by the commuting habits of members of the ÉTS community through a survey to determine their habits (distance travelled, mode(s) of transportation, frequency). The emission factors used are those chosen by the Fonds d'action québécois pour le développement durable and by the Société de transport de Montréal.

The ÉTS is currently developing a strategy to measure, reduce and offset Scope 3 emissions in a near future.

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

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

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:

Gross Scope 2 GHG emissions from purchased electricity (location-based):

Gross Scope 2 GHG emissions from imported thermal energy (location-based) :

Additional documentation to support the submission:

The published 2018-2019 GHG inventory does not report scope 1 emissions related to fugitive emissions and transportation because actual data was not available when the inventory was conducted. However, they have been estimated, upwards to be conservative, at 289 tons of CO2 eq. This is why the inventory shows a total of 1710 tons, but ÉTS has neutralized its GHG emissions for the years 2021 and 2022 up to 2000 tons annually via the purchase of Gold Standard carbon credits.

Scope 3 GHG emissions from commuting are not included in the GHG inventory, but are instead available in a separate report, a summary of which is attached here. The calculation of these emissions and the related report were produced after the 2018-2019 inventory.
