Pricing carbon pollution from industry - Canada.ca

Pricing Carbon Pollution in CanadaWhy Canada Needs An Output-Based Pricing SystemProceeds from Pricing Carbon PollutionConsultation ProcessNext StepsUnder the Greenhouse Gas Pollution Pricing Act, which came into force on June 21, 2018, the federal carbon pollution pricing system (also known as the federal backstop) has two parts: 1. a pollution price on fuel, known as the fuel charge; 2. a pollution price for industry, known as the Output-Based Pricing System (OBPS). In order to ensure that carbon pollution pricing applies throughout Canada, the federal government is putting this system in place in any province or territory that requests it or that does not implement its own system that meets the federal benchmark requirements: 1. The federal fuel charge took effect in April 2019 in Ontario, New Brunswick, Manitoba, and Saskatchewan, and will apply in Alberta on January 1, 2020. 2.
