Greenhouse gas emissions in Canada 1990-2022, by province
Alberta was Canada’s most polluting province by far in 2022, having emitted over *** million metric tons of carbon dioxide equivalent (MtCOâ‚‚e). This was an increase of ** percent compared to 1990 levels. Ontario – Canada's most populous province – was responsible for the second-largest volume of GHG emissions in 2022, at *** MtCOâ‚‚e. Unlike Alberta, Ontario’s emissions have fallen since 2005.Â
Canada’s oil sands emissions
Alberta’s large oil and gas industry is the main contributor to the province’s high emissions. Alberta is home to vast oil sands where some of the most carbon polluting sites in Canada are located – such as the Syncrude project on the Athabasca Oil Sands Deposit. The Syncrude Project is a joint venture between Suncor Energy, Imperial Oil, Sinopec, and CNOOC.
Canada's national emissionsÂ
Canada's national GHG emissions increased by *** percent in 2022, to *** MtCOâ‚‚e. The North American country has set the target of cutting its national GHG emissions by at least ** percent by 2030, relative to 2005 levels. However, as of 2022, Canada's emissions were just percent lower than they were in 2005.
