Report greenhouse gas (GHG) emissions

The rules for reporting greenhouse gas emissions.

The law

By law, you must report greenhouse gas emissions, if:

  • your facility releases 25,000+ tonnes of greenhouse gases (GHGs) in a year, and
  • GHGs come from a particular source identified under provincial regulations

Emissions data is collected to:

  • provide a baseline for companies
  • be used as a tool to guide the reporting process
  • help to understand, manage and cut emissions

Source law

A full set of provincial rules related to reporting are set out in:

What to report

You must report greenhouse gas emissions that come from the list of 26 sources (e.g., steel manufacturing) outlined in the regulation.

See: list of sources

When to report

You must submit a GHG emissions report every year by June 1, for the previous year's reporting period.

Example: June 1, 2013 for the reporting year 2012.

See: past GHG emissions report

Submit a report

You must submit a GHG emissions report using Environment Canada's Single Window System.

This system allows you to submit, view and update your information using Environment Canada applications.

Verify reports

Before you submit a GHG emissions report:

  • an accredited third party must confirm that the report is accurate
  • a member of the International Accreditation Forum must verify that the report meets international standards (ISO 14065)

See: ISO 14065

Third party evaluation

The third party will evaluate your report to determine if:

  • any errors due to measurements or calculations are fewer than 5%
  • the report was prepared according to the rules and guidelines under the law

This could include:

  • reviewing your documentation
  • reviewing your data controls and information management systems
  • visiting your facility
  • developing a verification report

Who can verify

You can find a list of eligible organizations that can verify emissions reports at:

Submit proof of verification

Once your emissions report has been verified, you must submit the verification statement you get from the third party organization.

You submit this statement through Environment Canada's Single Window System.

Deadline for verification statements

By September 1, for the previous year reporting period.

Example: September 1, 2013 for the reporting year 2012.

Timelines

The verification process usually takes 2 - 4 months. It is considered complete once you have written approval from the Ministry of the Environment and Climate Change.

Third party verification rules

As the accredited organization verifying an emissions report, you must:

  • submit an assessment form the Compromised Impartiality Assessment form for every facility you review
  • include a mitigation plan, for a particular facility, if you determine that there may be a conflict of interest
  • provide the facility with a verification statement to confirm that you have reviewed their GHG emissions report

Submit an assessment form

To submit an assessment form:

  1. download a Compromised Impartiality Assessment form
  2. complete and save the form
  3. submit the form to:

Mail:
