Canada's latest clean fuel regulations, in force since 2022, require gasoline and diesel primary suppliers (i.e. producers and importers) to reduce the carbon intensity (CI) of the gasoline and diesel they produce in, and import into, Canada from 2016 CI levels by 3.5 grams of carbon dioxide equivalent per megajoule (gCO2e/MJ) in 2023, increasing to 14 gCO2e/MJ in 2030. The regulations will also establish a credit market whereby the annual CI reduction requirement could be met via three main categories of credit-creating actions: (1) actions that reduce the CI of the fossil fuel throughout its lifecycle, (2) supplying low-carbon fuels, and (3) supplying fuel and energy in advanced vehicle technologies.
