This page provides information about the Technology Innovation and Emissions Reduction (TIER) system specific to the conventional oil and gas industry.

The Government of Canada applied a federal fuel charge in Alberta on January 1, 2020 under the Greenhouse Gas Pollution Pricing Act (GGPPA). The fuel charge applies to fossil fuels used in the province.

On January 1, 2020, the Government of Alberta introduced the TIER Regulation – the province’s improved approach to reducing greenhouse gas emissions from large industrial facilities which replaced the Carbon Competitiveness Incentive Regulation.

The GGPPA includes provisions to exempt facilities regulated under provincial policies that meet federal criteria. TIER meets federal requirements and protects regulated facilities from the GGPPA, while achieving emissions reductions using an approach that is cost-efficient and tailored to Alberta’s industries and priorities.

The TIER regulation automatically applies to facilities that emitted 100,000 tonnes CO2e or more per year of greenhouse gases (GHGs) in 2016, or a subsequent year.

To protect industry from the costs of the federal fuel charge, the Government of Alberta is also allowing eligible conventional oil and gas facilities with less than 100,000 tonnes CO2e per year to voluntarily enter into the TIER system. Additional information about eligibility and the application process is available on this page.

A facility regulated under TIER may apply for an exemption from the federal GGPPA requirements and would only be subject to the compliance requirements of the provincial TIER system.

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.


Application forms

Aggregation application

The owner of two 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 facility aggregate.

An aggregate facility is a combination of conventional oil and gas facilities that are treated as a single facility. The aggregate facility treatment streamlines the reporting and compliance process and simplifies the administrative requirements of the TIER system.

Federal fuel charge exemption application

As a person responsible for a facility regulated under TIER, you can register as an emitter with the Canada Revenue Agency (CRA). Registering as an emitter with the CRA will allow you to obtain an exemption certificate, which you can provide to your fuel supplier(s). This will allow deliveries of fuel to be made to you without the application of the federal fuel charge at the time of delivery if the fuel is for use at your facility, or any of the individual facilities of your aggregate facility, subject to certain conditions.

Additional information on how to register as an emitter with the CRA:

Updates to existing aggregates

The following form should be used to request additions or removals of conventional oil and gas facilities and/or individual Petrinex facilities from existing aggregates.

Removals take effect for the following calendar year. Additions will be reviewed and approved as received.

Application for a facility-specific benchmark

For benchmarking purposes, the person responsible for an aggregate facility may choose two or three reference years within the three consecutive year period beginning with the year prior to the first year of being registered under TIER. For aggregates that entered TIER in 2021, the reference year for 2021 compliance will be 2020 where that data is obtainable.

The following forms may be used by an aggregate facility to submit a facility specific benchmark application or request a benchmark unit. As well, a benchmark unit option 2 support workbook provides additional guidance to those aggregate facilities that are selecting option 2 for their benchmark unit approach.

General information about benchmarks for aggregate facilities can be found in the Standard for Developing Benchmarks.

The following instructional video provides an overview for filling out the above forms.

Compliance reporting documents

All facilities are required to submit verified annual compliance reports yearly by June 30 of the following year. Reference materials will be available on this page.

The following instructional video provides an overview for filling out the 2020 benchmark version of the compliance form.

Verification documents

Applications for facility specific benchmarks and compliance reports require third party verification.

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.

If you are a designated signing authority, lead verifier or peer reviewer and have not taken the training in one of the live sessions please review the training below and submit a quiz to [email protected].

Quantification methodologies

Quantification methodologies for aggregate facilities are provided in the Alberta Greenhouse Gas Quantification Methodologies (AQM).

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 an aggregate or a conventional oil and gas facility that is part of an aggregate, if a conventional oil and gas facility has emissions greater than 100,000 tonnes of carbon dioxide equivalent or if a conventional oil and gas facility is decommissioned.

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 for person responsible.
