Emission offsets are generated by projects that have voluntarily reduced their greenhouse gas emissions. Emission offsets are quantified using Alberta-approved methodologies called quantification protocols, and are verified by a third party in accordance with the Standard for Validation, Verification and Audit.

Emission offset projects must meet the requirements in the Technology Innovation and Emissions Reduction (TIER) regulation, the Standard for Greenhouse Gas Emission Offset Project Developers, and a relevant Alberta-approved quantification protocol.

Emission offsets are registered and listed on the Alberta Emissions Offset Registry operated by CSA Group.
