Cap-and-Trade Regulations


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
