Government of Yukon amends Air Emissions Regulation to reduce air pollutants and support a cleaner future

Jun 06, 2025

Protecting air quality and human health is a key priority of the Government of Yukon’s commitment to shaping a healthier, cleaner future for Yukoners. As part of its Our Clean Future climate strategy, the Government of Yukon is amending the Air Emissions Regulation to help minimize the release of harmful air pollutants from large-scale biomass burning systems, such as those found in schools, offices or large commercial buildings.

Under the amended Regulation, biomass burning units equal to or greater than 150 kilowatts of heat output, of which there are currently four in the Yukon, will require an air emissions permit.

The changes to the Regulation will come into effect on July 1, 2025. Any future systems will require an air emissions permit prior to initial startup and owners and operators of existing systems will require an air emissions permit by December 31, 2025.

The six-month transition period provides existing operators additional time to work with the Department of Environment to ensure their systems are in compliance with the amended Regulation.

Clean air matters – to our health, our communities and our environment. By regulating emissions from large-scale biomass systems, we are delivering on our Our Clean Future commitments and taking real steps to reduce air pollution. As more commercial and institutional buildings explore biomass as a cleaner energy option, we are helping ensure it is done responsibly.

The Regulation covers permitting, monitoring and enforcement of emissions from manufacturing of asphalt, production of natural gas, quarrying, processing and handling of coal, operation of incinerators for solid and special waste, operation of electricity generating facilities, storage of solid, liquid or gaseous substances and now biomass burning units equal or greater to 150 kilowatts.
