On December 19, 2020, the Government of Canada’s Department of the Environment published a proposed rule titled Clean Fuel Regulations. The proposed rule addresses Canada’s concerns in achieving its net-zero emissions by 2050 under the Paris Agreement. In an effort to reduce the largest sources of greenhouse gases (GHG), the Clean Fuel Regulations would require liquid fossil fuel primary suppliers to reduce the carbon intensity (CI) of the liquid fossil fuels they produce in and import into Canada from 2016 CI levels by 2.4 g of CO₂/megajoule (MJ) in 2022, increasing to 12 g of CO₂/MJ in 2030. The proposed rule would also establish a credit market whereby the annual CI reduction requirement could be met via three main categories of credit-creating actions:

• Actions that reduce the CI of the fossil fuel throughout its life cycle;

• Supplying low-carbon fuels; and

• Specified end-use fuel switching in transportation.

The Clean Fuels Regulations would also retain the minimum volumetric requirements of at least five percent low CI fuel content in gasoline and two percent low CI fuel content in diesel fuel and light fuel oil that are currently set out in the federal Renewable Fuels Regulation (RFR). The RFR would be repealed, and parties that are not primary fossil fuel suppliers would be able to participate in the credit market as voluntary credit creators by completing certain actions.
