Reporting emissions

  • Companies must use the standard reporting form to submit greenhouse gas emissions reports and any additional information listed in the regulations and standards to Nova Scotia Environment.
  • Reporting via SWIM is preferred. Follow the instructions (PDF) to register on SWIM. You must register before you can use it. Otherwise, reports can be submitted to GHGreporting@novascotia.ca.
  • Greenhouse gas emissions reports must be verified by an accredited third-party organization. Lists of eligible verification bodies are available at:
  • An attestation form must accompany greenhouse gas emissions reports for fuels sold to a facility that is participating in Nova Scotia’s cap-and-trade program.
  • This attestation form may also be used to document fuels that are exported outside of Nova Scotia or used exclusively in aviation or marine applications. Other documentation deemed acceptable by the verification body may also be used.

Registering in the program

Registration for the cap-and-trade program is now open. Participating companies must register using the Compliance Instrument Tracking System Service (CITSS)

Registration requirements are outlined in Section 5 of the Cap-and-Trade Program Regulations. Forms and documents required for each part of the registration process are below, along with guidance on how to complete the registration:

Part 1 – user registration

Part 2 – account application

Please send any questions about the registration process to capandtradehelp@novascotia.ca

Participating in auctions

60 days before an auction, the province will provide notice with details about participating in the event. Mandatory participants registered in the program may take part in an auction of emission allowances. Each auction participant must register as a bidder no later than 30 days before the auction and submit a financial guarantee to the province no later than 12 days before the auction.

Auctions will be administered through CITSS and Auction Platform. Each auction will have a single round of bidding using sealed bids. The emission allowances will be auctioned in lots of 1,000 emission allowances. The minimum price per allowance will increase annually by 5% plus inflation.

For auctions held in 2023, the minimum price will be $25.72.
