Federal framework
The Clean Fuel Regulations require primary suppliers of gasoline and diesel to reduce lifecycle carbon intensity. Compliance credits can be created through several categories, including the supply of lower-carbon-intensity fuels such as ethanol.
Credit value and ethanol commodity value are related commercial variables, but they are not interchangeable.
Provincial layers
Provinces can set renewable-content or carbon-intensity requirements. The obligated party, eligible fuel, carbon-intensity method and reporting rules differ, so a national summary should never substitute for the current provincial regulation.
Lifecycle boundaries matter
Feedstock production, processing energy, transportation and other pathway details affect carbon-intensity calculations. A broad label such as renewable does not determine the compliance value of a specific pathway.
