Platts proposes to launch Alberta TIER Emission Performance Credit and Offset Credit assessments

Platts, part of S&P Global Commodity Insights, is proposing to launch daily price assessments for Alberta Technology Innovation and Emissions Reduction (TIER) compliance instruments — including both Emission Performance Credits (EPC) and Alberta Emission Offset (AEO) credits — effective July 1, 2025.

These instruments are used by regulated entities in Alberta to comply with provincial carbon pricing obligations under the TIER program. EPCs are generated by facilities that outperform their emissions benchmarks, while AEO credits are issued for verified emission reductions from eligible projects outside the industrial regulated sector. Both credit types represent one metric ton of carbon dioxide equivalent (CO 2e) and are fungible within the TIER system for compliance use.

The proposed daily spot assessments aim to enhance market transparency and support risk management and trading activity in Alberta's growing carbon credit markets.

The assessments would reflect prevailing market prices for spot transactions involving eligible TIER EPCs and Offset Credits.

The proposed assessments would each have the following specifications:

Platts would consider all bids, offers, trades and indications received in both the over-the-counter (OTC) and exchange markets for assessment purposes.

The proposed EPCs and Offset Credits would be published in C$/mtCO2e and converted to $/mtCO2e using a proposed foreign exchange conversion rate with a 16:00 CST timestamp.

Details regarding the methodology for Platts Carbon assessments can be found here(opens in a new tab).
