The Greenhouse Gas Pollution Pricing Act implements a revenue-neutral carbon tax. In 2019, it started at $20/t, and was to increase $10/t a year to reach $50/t by 2022. Considering some states have carbon pricing systems (Alberta TIER 2007, British Columbia's carbon tax 2008, Quebec CaT 2013, Alberta's carbon tax 2017), the law will apply to states where no such policy is implemented. The policy also encompasses the Federal Fuel Charge.
