"The new regulations are meant to cut the “carbon intensity” of automotive fuels sold on the Canadian market — how much they generate in emissions for a given amount of energy. Unlike the current rules, the new ones cover the entire life cycle of fuels, from production and transport to consumption.

The goal is to push companies that produce or import fuel to gradually reduce the emissions intensity of that process by setting a ceiling and dropping it each year. By 2030, the rules will require a 15 per cent cut in emissions intensity compared to 2016 levels."
