Greenhouse Gas Emissions by Province and Territory

Greenhouse gas (GHG) emissions for Ontario and Quebec were lower in 2013 than in 1990 by a total of about 18 megatonnes (Mt) of carbon dioxide equivalent (CO2 eq) (11 Mt for Ontario and 7 Mt for Quebec). Emissions in Saskatchewan, Alberta and British Colombia were higher in 2013 than in 1990 by 30 Mt, 93 Mt and 11 Mt respectively. The top five emitters (Alberta, Ontario, Quebec, Saskatchewan and British Columbia) together released almost 91% of Canada's national total GHG emissions of 726 Mt of CO2 eq in 2013.

Ontario's GHG emissions were higher than those from the other provinces in 1990 because of its large manufacturing industry. Alberta's emissions subsequently surpassed Ontario's, increasing 53% since 1990, primarily because of the increase in production of petroleum products for export markets. Ontario's emissions decreased between 1990 and 2013 primarily because of the closure of coal-fired electricity generation plants. In 2013, the combined emissions from Alberta and Ontario represented 60.3% (36.8% and 23.5%, respectively) of the national total of 726 Mt of CO2 eq.

The provinces of Quebec and British Columbia, which rely on abundant hydroelectric resources for their electricity production, show more stable emission patterns across the time series and a decreasing pattern since 2005. Quebec exhibits an 8.4% (7.6 Mt) decrease from its 2005 emissions level; while British Columbia shows a decline of 2.6% (1.6 Mt). In contrast to these decreases, emissions in Saskatchewan increased by 7.6% (5.3 Mt) between 2005 and 2013, primarily due to increases from the transportation sector.
