Alberta Emission Offset System

Overview

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.

• For more overview information, see the TIER Alberta Emission Offset Fact Sheet.
