Carbon pricing: regulatory framework for the output-based pricing system


Carbon pricing is a central component of the Pan-Canadian Framework on Clean Growth and Climate Change (PCF). Carbon pricing is an efficient way to reduce greenhouse gas (GHG) emissions at the lowest cost to businesses and consumers, while stimulating innovation and clean growth.

In October 2016, the Government of Canada published the Pan-Canadian Approach to Pricing Carbon Pollution (the benchmark) to ensure that carbon pricing applies to a broad set of emission sources throughout Canada in 2018 with increasing stringency over time. Under the benchmark, provinces and territories can implement the type of carbon pricing system that makes sense for their circumstances--either an explicit price-based system (such as a carbon tax or carbon charge and performance-based emissions system) or cap-and-trade.  As part of the benchmark, the federal government also committed to implement a federal carbon pricing backstop that will apply in any province or territory that requests it or that does not have a carbon pricing system in place in 2018 that meets the benchmark (referred to as “backstop jurisdictions”). In early 2018, the Government of Canada will release a draft legislative proposal for the federal backstop for comment.

The Government of Canada has requested that provinces and territories that choose the federal backstop, in whole or in part, confirm this by March 30, 2018. Those opting to establish or maintain a provincial or territorial pricing system that meets the benchmark need to outline how they are doing so by September 1, 2018.  After reviewing each system, the Government of Canada intends to implement the federal backstop in whole or in part on January 1, 2019 in any province and territory that does not have a carbon pricing system that meets the benchmark. To minimize uncertainty for residents, businesses and investors, once in effect, the backstop will remain in effect until at least 2022.

From 2019 onwards, there will be an annual verification process to ensure carbon pricing systems continue to meet the benchmark. We will also monitor major changes to provincial and territorial systems on an ongoing basis.

In May 2017, the federal government released a Technical Paper on the Federal Carbon Pricing BackstopFootnote 1  outlining the federal carbon pricing backstop with two elements:

The aim of the OBPS is to minimize competitiveness risks for emissions-intensive, trade-exposed industrial facilities, while retaining the carbon price signal and incentive to reduce GHG emissions. The charge is not intended to apply to fuel used at a facility that is part of the OBPS. Each OBPS facilityFootnote 4  will instead be subject to the carbon price on the portion of emissions that exceed an annual output-based emissions limit. In jurisdictions where the backstop applies, the OBPS will apply to industrial facilities that emit 50 kilotonnes (kt) CO2e or more and for which an output-based standard is specified, or that emit between 10 and 50 kt CO2e per year and whose application for voluntary participation is approved.

This paper provides additional information on the proposed design of the OBPS, and seeks further input from the public and stakeholders on key technical issues to inform its development.

Design principles of the Output-Based Pricing System

The OBPS is based on the following principles, subject to practical considerations:

  1. Deliver incremental GHG emissions reductions
    The OBPS will create incentives for incremental GHG emission reductions (meaning fewer emissions than would have occurred without the OBPS in place).
  2. Minimize carbon leakage and competitiveness risks
    The OBPS will be designed to minimize carbon leakage by limiting impacts on competiveness from carbon pricing for large industrial facilities.
  3. Treat OBPS participants in a consistent manner
    The design of output-based standards will be consistent within and across sectors and products.
  4. Provide transparency
    The OBPS will be implemented in a transparent manner.
  5. Commitment to review
    The OBPS will be reviewed by 2022, in conjunction with the review of the overall pan-Canadian approach to carbon pricing, committed to as part of the Pan-Canadian Framework on Clean Growth and Climate Change.

Overview of the Output-Based Pricing System

Industrial facilities that are registered under the OBPS will be able to purchase charge-free fuel from the time the charge starts to apply. OBPS facilities will instead be subject to the carbon price on the portion of their emissions that exceed an annual output-based emissions limit.

An OBPS facility’s annual GHG emissions limit, expressed in tonnes of CO2e, will be based on the prescribed output-based standards (OBS) for the production activities that the facility undertakes. The limit for a single product facility will be determined by multiplying the applicable output-based standard and the facility’s total annual production. For a facility to which more than one output-based standard applies, the annual facility emissions limit will be based on the sum of the limits for each product, expressed as follows:  

Annual Facility Emissions Limit (tonnes CO2e) = i=1 n [OBSi ( tonnes CO2e units i ) × Productioni (units i) ]

The compliance obligation of a facility will be calculated as follows:

Compliance obligation (tonnes CO2e) = Total annual facility emissions - Annual facility emissions limit

The Government of Canada will issue surplus credits to facilities whose emissions are below their annual facility emissions limit. Each surplus credit will represent one tonne of CO2e.

A facility whose emissions are above its limit will have three options to meet its obligation:

Regulated facilities

The OBPS will apply to facilities:

Consideration is being given to which year(s) will be included when assessing a facility’s emissions against the threshold of 50 kt CO2e.

The OBPS will not apply to buildings (including municipal, hospitals, universities, schools, and commercial), or landfills not associated with an OBPS facility, municipal wastewater treatment facilities or to natural gas distribution pipelines.

Facilities that meet the 50 kt CO2e threshold will be required to register with Environment and Climate Change Canada.

Voluntary participation in the Output-Based Pricing System (opt-in)

Facilities in backstop jurisdictions with annual emissions between 10 kt CO2e and 50 kt CO2e and that carry out an activity for which an output-based standard has been prescribed will be able to opt-in to the OBPS starting with the January 1 to December 31, 2020 compliance period (i.e., they will purchase charge-in fuel during 2019). Once a facility opts-in, it will be subject to the same obligations as all other OBPS facilities and will be able to purchase charge-free fuel.

A facility wishing to opt-in will need to submit a request to Environment and Climate Change Canada in advance of the first year in which it would like to be subject to the OBPS. Environment and Climate Change Canada will review each application and will designate approved applicants. For those facilities, the OBPS will apply starting at the beginning of the next relevant compliance period.

Additional information will be provided following further consultation on the eligibility criteria and process for opting in.

Covered emission sources

Covered emission sources will include fuel combustion, industrial process, flaring, and some venting and fugitive sources. Methane venting and methane fugitive emissions from oil and gas facilities will not be subject to pricing under the OBPS.

Emissions of all seven of the United Nations Framework Convention on Climate Change (UNFCCC) greenhouse gases will be included, to the extent practicable – carbon dioxide (CO2)Footnote 6 , methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6) and nitrogen trifluoride (NF3).

Output-based standards

To the extent practicable, output-based standards will be developed using a consistent approach across sectors.

In most cases, output-based standards will be set as a percentage of the production-weighted national average of emission intensityFootnote 7 . In some cases it may be necessary to use alternate metrics that better characterize the sector.

The proposed starting percentage for all output-based standards will be 70% of the production-weighted national average of emission intensity (i.e., the output-based standard will be set 30% below the production-weighted national average of emission intensity). That percentage may be adjusted based on various considerations, such as the emissions intensity of the best-in-class performer (the facility with the lowest emissions intensity); the distribution of emissions intensities among facilities in the sector; and potential impacts on competitiveness.

The stringency of output-based standards will increase over time. Consideration is being given to different approaches, including a fixed annual percent reduction and scheduled revisions at multi-year intervals.

Output-based standards will initially be developed for the following industrial sectors: oil and gas, pulp and paper, chemicals, nitrogen-fertilizers, lime, cement, base metal smelting and refining, potash, iron ore pelletizing, mining, iron and steel, and food processing. Over time, output-based standards for additional sectors may be developed.

To address heterogeneity within some sectors, output-based standards may be developed within sub-sector categories at a product level, or in some cases, for a grouping of products, as illustrated in Table 1.

Consideration is being given to how to apply carbon pricing to offshore oil and gas production and to electricity generation.

Developing new output-based standards

Although all efforts will be made to ensure that output-based standards are developed for all types of eligible facilities, there may be facilities in a backstop jurisdiction that meet the 50 kt CO2e threshold, or facilities that have annual emissions between 10 kt and 50 kt CO2e, for which an output-based standard has not been prescribed. For example, the need for an output-based standard for a facility producing a new product line that is unique to Canada, may not be identified in advance. Options to enable these facilities to participate in the OBPS after 2020 are being considered.

Treatment of indirect emissions

Many facilities produce energy and intermediate products on-site, with the resulting emissions occurring on-site. Other facilities may purchase energy and intermediate products from third parties. The emissions associated with this energy production and these intermediate products occur off-site and are considered “indirect emissions”. Consideration is being given to how to address these emissions under the OBPS.


Compliance periods will generally be on a calendar year basis (i.e. January 1 to December 31).

Facilities will be required to submit a compliance report for each compliance period.

Compliance reports will include the information needed to assess whether the facility meets its compliance obligations. This information will include: the facility’s annual emissions limit, its total emissions, and its calculated compliance obligation. Reports will also include information such as total emissions by activity/product; quantity of fuel used by type of fuel; production, sale, and purchase of key products such as electricity, steam, and hydrogen; and information related to facility emissions that are not subject to pricing.

Facilities will be required to quantify their emissions using prescribed methodologies, and will need to arrange for their annual compliance reports to be third-party verified to a reasonable level of assurance by verification bodies that are accredited to ISO 14065 by the Standards Council of Canada or the American National Standards Institute.

Consideration is being given to setting a deadline for submission of compliance reports of June 1 the year following the compliance year (e.g., reports would be due June 1, 2020 for a compliance period ending Dec. 31, 2019).

Facilities that emit above their annual facility emissions limit will need to fulfill compliance obligations by a set date. Consideration is being given to setting that deadline as November 1 of the year following the compliance year.

Compliance units

Consideration is being given to the need for, and the design of, rules designed to enhance market liquidity (i.e., to encourage trading of surplus credits among OBPS participants). Examples include limits on the banking and holding of credits.

Further information will be provided on eligible offset credits in a forthcoming guidance paper. This will build on the recommendations of the pan-Canadian Offset Framework report of the Canadian Council of Ministers of the Environment.

Tracking systems for compliance units

A tracking and compliance assessment system to track issuance and use of OBPS surplus credits and the use of eligible offsets will be developed. Each OBPS facility will be required to open accounts in the tracking system.

Review and update

The Pan-Canadian Framework includes a commitment for a review of the overall approach to carbon pricing by early 2022 to confirm the path forward. An interim report will also be completed in 2020. The design of the OBPS may be adjusted in response to these reviews.

Next steps and engagement process

The federal government plans to introduce legislation and regulations to implement the carbon pricing backstop system, including the OBPS, in jurisdictions that request it or that do not have a system in place in 2018 that meets the pan-Canadian benchmark.

In jurisdictions where both components of the federal backstop apply (the charge and the OBPS), both components will take effect at the same time. Registered OBPS facilities will be able to access charge-free fuel from the time the charge starts to apply.

Environment and Climate Change Canada will undertake structured engagement on the OBPS in the winter/spring 2018. This will include engagement and consultation with provinces and territories, Indigenous Peoples, environmental non-governmental organizations, industry, and business. Further details will be made available in advance of the start of consultations.

In the meantime, interested parties wishing to comment on any aspect of this Framework are invited to provide written comments to Environment and Climate Change Canada at the following address, on or before April 9, 2018:
