Alberta Emission Offset System

The Emission Offset System enables compliance flexibility for facilities regulated under TIER.


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.

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

Approved protocols

Flagged protocols

The following protocols are flagged, which means that a project developer cannot initiate or implement an emission offset project without written authorization from the director.

For more information on applying to the director to use a flagged protocol, please see the Standard for Greenhouse Gas Emission Offset Project Developers.

Withdrawn protocols

The following protocols are withdrawn, which means that no new projects can be initiated using these protocols. For information on withdrawn protocols, see the Standard for Greenhouse Gas Emission Offset Project Developers.

Documents for comment

Alberta's protocol development process is outlined in the Technical Guidance for Offset Protocol Development and Revision. As part of the development and revision process, draft protocols are posted for a 30-day public comment period.
