The Technology Innovation and Emissions Reduction (TIER) Regulation is Alberta’s industrial greenhouse gas emissions pricing regulation and emissions trading system. Facilities regulated under TIER must reduce emissions to meet facility benchmarks.

TIER applies to about 60% of Alberta’s emissions. Facilities that reduce emissions beyond their benchmark can generate emissions performance credits. Facilities that do not directly meet their benchmark can comply in one of three ways:

  • submit Alberta Emission Offsets generated from qualifying emissions reductions outside of regulated facilities
  • submit emissions performance credits
  • obtain fund credits by paying the prescribed price (PDF, 84 KB) into the TIER fund

TIER replaced the Carbon Competitiveness Incentive Regulation (CCIR) on January 1, 2020.

TIER facilities are exempt from paying the federal fuel charge. The TIER regulation applies to facilities that emitted 100,000 tonnes of carbon dioxide equivalent CO2e or more per year of greenhouse gases in 2016, or a subsequent year.

A facility with less than 100,000 tonnes CO2e per year may be eligible to opt-in to the TIER if it competes against a facility regulated under the TIER regulation, or emits 10,000 tonnes CO2e or more per year and belongs to a sector with high emissions intensity and trade exposure.

The owner of two more conventional oil and gas facilities may apply to have those facilities regulated under the TIER regulation by applying to form a conventional oil and gas aggregate. More information for conventional oil and gas facilities is available on the TIER Conventional Oil and Gas sector TIER website.

Facility owners may also be eligible to receive economic relief under the Compliance Cost Containment Program.

The Alberta Emission Offset System enables the generation of Alberta Emission Offsets as a method of compliance under TIER.

The TIER regulation was amended in July 2020 to allow additional sectors to voluntarily opt-in to the regulation and reduce administrative burden for regulated conventional oil and gas facilities. The amendments can be reviewed in Order in Council (233/2020) (PDF, 230 KB).


Opt-in application

Facilities that satisfy the criteria under the regulation may apply to opt-in to the regulation.

By opting in, facilities may apply to become exempt from the application of the Greenhouse Gas Pollution Pricing Act (GGPPA) for fuels whose emissions are included in their site reporting.


The owner of 2 or more conventional oil and gas facilities may apply to have those facilities regulated under the TIER regulation by applying to form a conventional oil and gas aggregate facility.

Additional information is available on the TIER Conventional Oil and Gas sector website.

Benchmark setting

The TIER regulation makes use of both facility specific and high performance benchmarks. Details of the benchmark setting process are available here:

Large emitters and opted-in facilities can apply for benchmarks using the following forms. These apply to facilities with one product or facilities with multiple products including facilities with self-generation of electricity:

The following instructional videos provide a step-by-step overview for filling out the forms:

Compliance reporting

All facilities are required to submit verified annual compliance reports yearly by June 30 of the following year. Supporting documents for the compliance reporting process will be published on this page.

The following instructional video provides an overview for filling out the compliance form.

Forecasting report

Forecasting reports are required under the regulation for facilities that have had emissions of one million tonnes CO2e or more per year.

Verification documents

Compliance reporting and benchmark applications require third party assurance.

Verification training requirement

Lead verifiers, peer reviewers, and designated signing authorities completing verifications for 2020 compliance reports submitted by June 30, 2021 and benchmark applications submitted by September 1, 2021 are required to complete the TIER-specific verification training. Training is encouraged but is not mandatory for verification of emission offset project reports submitted in 2021.

The following verification training materials are provided for 2021:

Verification training materials for third party assurance providers completing verifications in 2022 and subsequent years is in development.

Quantification methodologies

Alberta Greenhouse Gas Quantification Methodologies (AQM) for emissions, production and other reported data are prescribed for facilities that are subject to the Technology Innovation and Emissions Reduction Regulation and the Specified Gas Reporting Regulation.

The finalized AQM includes the following chapters:

  • Chapter 1: Stationary Fuel Combustion
  • Chapter 2: Flaring
  • Chapter 4: Venting
  • Chapter 5: On-Site Transportation
  • Chapter 8: Industrial Processes
  • Chapter 12: Imports
  • Chapter 13: Production
  • Chapter 14: Carbon Dioxide Emissions from Combustion of Biomass
  • Chapter 15: Aggregate Facilities
  • Chapter 16: Cogeneration Benchmark Calculations
  • Chapter 17: Measurements, Sampling, Analysis and Data Management
  • Appendix A: References
  • Appendix B: Fuel Properties
  • Appendix C: General Calculation Instructions
  • Appendix D: Conversion Factors
  • Appendix E: Additional Information for the Alberta Gas Processing Index

Responses to comments and questions on draft of Chapter 2: Flaring

The following table summarizing comments and questions received and AEP responses.

Deviation Request form

If a facility is unable to meet any mandatory quantification methodologies, the facility may submit a deviation request to the director for review and approval. If accepted, the director may approve a deviation for a period of up to 12 months. Refer to the AQM and Standard for Completing Greenhouse Gas Compliance and Forecasting Reports for details to deviation requests.

The following form may be completed and submitted to the director at [email protected].

Notification of changes

All facilities are required to submit a notification of certain changes to the facility as set out in section 25 of the regulation. These include changes to the person responsible for a large emitter or opt-in facility.

The following form should be used for this purpose:

The form may also be voluntarily used to notify of a change in the certifying official or reporter.

Compliance Cost Containment Program

If TIER regulation compliance costs exceed 3% of sales or 10% of profit at a facility, the owner of that facility may be eligible to receive relief under the Compliance Cost Containment Program. Additional information is available in the Standard for Developing Benchmarks.
