Carbon dioxide emissions in Canada 1960-2021

Canada’s carbon dioxide emissions from fossil fuel combustion and industrial processes totaled 545.6 million metric tons in 2021. This was an increase of around two percent in comparison to the previous year, when CO₂ emissions saw a major reduction due to the COVID-19 outbreak and its subsequent impacts.

Energy related emissions

A large percentage of global greenhouse gas emissions are derived from the production and consumption of energy. In Canada, energy-related emissions account for an even higher share of total emissions due to extreme temperatures, large land area, and dispersed populations. The energy sector's greenhouse gas emissions in Canada amount to roughly 600 million metric tons of CO₂ equivalent each year. Oil and gas sector emissions in Canada were nearly 180 million metric tons in 2020.

Which Canadian province is the largest GHG emitter?

Alberta is the largest emitter of greenhouse gas emissions in Canada. Oil production in Alberta contributes to the province’s high emission levels, especially under periods of increased oil sands production. However, technological and efficiency improvements have helped reduce the oil sands emissions per barrel.
