Amendments to the Environment Act allow government to create the cap-and-trade program and regulations to support it.
Cap-and-trade program regulations
The Cap-and-Trade Program Regulations and framework document outline how the program works. They include greenhouse gas emission caps, rules for distributing, buying and selling greenhouse gas allowances, and other details.
Reporting emissions and participating in cap and trade
The following types of companies must report their greenhouse gas emissions, get them verified by a third party, and participate in the cap-and-trade program:
- Facilities that generate 50,000 tonnes of greenhouse gas emissions or more per year from one or more specified activities
- 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 greenhouse gas emissions or more per year
- Electricity importers with 10,000 tonnes of greenhouse gas emissions or more per year from imported electricity consumed in Nova Scotia
The rules for reporting greenhouse gas emissions are outlined in:
- Quantification, Reporting, and Verification of Greenhouse Gas Emissions Regulations
- Standards for Quantification, Reporting, and Verification of Greenhouse Gas Emissions
Petroleum product pricing regulations
Amendments to the Petroleum Product Pricing Regulations allow the Utility and Review Board to apply the carbon price to gas and diesel.

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 2022, the minimum price will be $22.92
