Does the institution have policies and/or guidelines in place to improve outdoor air quality and minimize air pollutant emissions from mobile sources on campus?:

A brief description of the policies and/or guidelines to improve outdoor air quality and minimize air pollutant emissions from mobile sources:


On July 11, 2014 the University of Alberta updated its Vehicle Management and Driver Safety policy to include a section that prohibits idling when using one of the institution's fleet vehicles. While there is no formal penalty for idling, the presence of an anti-idling section in the policy enhances the internalization of the values behind idling reduction within the campus community.

For Health and Safety reasons pertaining to indoor air quality, idling is prohibited near identified fresh air intakes of campus buildings, but a policy prohibiting idling by commuter vehicles has not been adopted to date.


UAlberta also has permanent "Care for Our Air" signage installed across campus reminding drivers to limit their vehicle idling. There are also Care for Our Air reminder stickers in each of the fleet vehicles.


UAlberta Transportation Services is trying out some new technology to help with idling reduction. The GPS vehicle locator system that was deployed in 79 fleet vehicles in 2016 was updated in 2020. The system assists the university in reducing travel time and idling. All vehicles used on campus are maintained for optimal efficiency, and multiple van and truck trips on campus have been eliminated by providing a shuttle van for trades groups to move around campus.


The trades group made a further improvement by creating two satellite shops in parts of North Campus where trades work is often required; the creation of these satellite shops allowed them to downsize by three fleet vehicles. In addition, the trades group has replaced some vehicles with smaller gas-powered gators, which consume less fuel than a van or truck would for the same vehicle usage.

Has the institution completed an inventory of significant air emissions from stationary campus sources or else verified that no such emissions are produced?:

Weight of the following categories of air emissions from stationary sources::
Weight of Emissions
Nitrogen oxides (NOx) 258.30 Metric tons
Sulfur oxides (SOx) 1.37 Metric tons
Carbon monoxide (CO) 193.40 Metric tons
Particulate matter (PM) 0.55 Metric tons
Ozone (O3) ---
Lead (Pb) ---
Hazardous air pollutants (HAPs) ---
Ozone-depleting compounds (ODCs) 0.80 Metric tons
Other standard categories of air emissions identified in permits and/or regulations 12.50 Metric tons

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


The university has completed an inventory of its significant air emissions produced by the district energy system for calendar year 2019 (which includes natural gas electricity generation). These emissions include Heating Plant boiler emissions and do not include the emissions from diesel generators and fork lift truck (these sources represent 0.2% of the total Heating Plant emissions, and are considered immaterial).

Emissions were determined using the 2019 Natural Gas Combustion Emissions Calculator, which is used to facilitate the calculation of air emissions from natural gas combustion for the natural gas industry and their customers to use in reporting to the Alberta Environment 2019 Alberta Emissions Inventory Report (AEIR). The Calculator is an updated version of the 2018 Calculator, by the Canadian Energy Partnership for Environmental Innovation (CEPEI). It is an equipment-based Excel® spreadsheet accompanied by two guidance documents (a User's Manual that assists in filling-out the information required and a Methodologies Manual that describes the calculations and emissions factors used).

The NOx emissions are actual measured emissions from the DES' continuous emission monitoring system (CEMS), rather than the estimate from the calculator.

The HCFC-22 emissions number provided is the estimated fugitive emissions from refrigerant loss, from the university's greenhouse gas inventory.


An air emissions estimate was completed based on building area for all other campuses and sites within the STARS boundary. These estimates have been added to the North Campus figures above. North Campus accounts for approximately 85% of the university based on floor area.


The university does not have data for:
- Ozone (not measured/not produced)
- Lead (not measured/not produced)
