Energy use and greenhouse gas emissions
A wide variety of factors have an influence on the level of GHG emissions in Canada. Globally, about 78% of GHG emissions from human activity are from the production and consumption of energy. This includes activities such as using gasoline for transportation, non-renewable electricity production, oil and gas production, and heating and cooling of buildings.
In Canada, over 81% of emissions come from energy. Canadians use more energy due to our extreme temperatures, vast landscape and dispersed population.
