Greenhouse gas emission reporting

New regulations are now in effect for reporting greenhouse gas (GHG) emissions.

Collecting and publicly reporting GHG emissions supports the implementation of our cap and trade program which will help continue reducing emissions in Nova Scotia. Thresholds set in these regulations will ensure that most of the GHG emissions in the province are captured in the cap and trade program.

The regulations took effect February 15, 2018. They apply to GHG emissions released from specified GHG activities that are carried out on or after January 1, 2017.

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

Companies required to report and get reports verified  

The following types of companies must report their GHG emissions and get them verified by a third party:

  • Facilities that generate 50,000 tonnes of GHG emissions or more per year from one or more of the following GHG activities:
    • Cement production
    • Coal storage
    • Electricity generation
    • General stationary combustion
    • Industrial wastewater
    • Operation of equipment for a transmission system or a distribution system (electricity)
    • Operation of equipment related to the transmission, storage and transportation of natural gas
    • Petroleum and natural gas production and natural gas processing
    • Pulp and paper production
    • Underground coal mining
    • Distributing natural gas
    • Supplying petroleum products
  • Petroleum product suppliers that first place or produce 200 litres of fuel or more per year for consumption in the Nova Scotia market.
  • Natural gas distributers that deliver natural gas for consumption in Nova Scotia that, when combusted, produces 10,000 tonnes of GHG emissions or more per year

Preparing and submitting GHG reports

Companies that engage in activities outlined above and meet or exceed any applicable reporting thresholds must report these GHG emissions to Nova Scotia Environment.

Companies may use the GHG reporting template (389 KB XLSX). It will help them organize and prepare a GHG report.

Companies must submit GHG report and any additional information to Nova Scotia Environment at .

Deadline for GHG reports

In the first year, companies must report by May 15, 2018. In subsequent years, companies will report by June 1. Reporting is for the previous calendar year:

  • May 15, 2018 – report for 2017
  • June 1, 2019 – report for 2018

Additional Guidance- May 2, 2018

Based on the feedback received from emitters regarding challenges in collecting and reporting certain data during this first reporting period, NSE is providing this additional guidance document for 2018 GHG reports. Additional guidance provided in March 2018 is included and updated here.

Verifying GHG reports

GHG emissions reports must be verified by accredited third-party organizations.

Verification is an independent quality assurance process. It provides confidence that the data reported is accurate enough to meet the requirements in the reporting regulations and adheres to a specific set of criteria such as ISO 14064-3.

The third-party verifier will evaluate reports to determine if:

  • Any errors in emissions due to measurements or calculations are fewer than 5%
  • Any errors in production data are fewer than 0.1%
  • The report was prepared according to the regulations and standard

This could include:

  • Reviewing the company’s documentation
  • Reviewing the company’s data controls and information management systems
  • Visiting the company’s facility, headquarters or other locations
  • Developing a verification report

Third-party verification bodies

The Standards Council of Canada and the American National Standard Institute are accrediting bodies that are recognized throughout North America. Both are members of the International Accreditation Forum under ISO 17011 and are authorized to accredit validation and verification bodies in compliance with ISO 14065.

Lists of eligible organizations that can verify emissions reports are available at:

Submitting verification reports

Companies must submit a verification statement and a verification report from the third-party verification body to Nova Scotia Environment at .

Deadline for verification reports

Companies must provide verification statements and verification reports by September 1 for the previous calendar year:

  • September 1, 2018 – verification of report for 2017
  • September 1, 2019 – verification of report for 2018
