The Technology Innovation and Emissions Reduction (TIER) Regulation system is undergoing a legislated review. TIER is Alberta’s third generation of an industrial carbon pricing and emissions trading system, building on regulations and systems that first came into effect in 2007.

Alberta is making great progress on lowering greenhouse gas emissions through our real-world, common sense approach, but we recognize there is opportunity for constant improvement. That’s why we’re gathering input from industry, Indigenous communities and Albertans on ways to continue to make the TIER system better. We will consider feedback received as the TIER review is complete in 2022.
