A federal fuel charge of $20/tonne of carbon emissions came into effect on April 1, 2019, as a means to reduce Greenhouse Gas (GHG) Emissions. The fuel charge assigns a value to each tonne of GHG emissions, measured in carbon dioxide equivalent (tCO2e), beginning at $20/tCO2e in 2019 and increasing by $10 annually to $50/tCO2e in 2022.
