Regional greenhouse gas (GHG) emissions by sectors of the economy for 1998 are shown here. The map also shows the regional carbon intensity measured in tonnes of CO2-equivalent to per million dollars of Real Domestic Product. The share of economic sectors in the total regional GHG emissions depends on the region's economic structure and availability of energy resources. The share of greenhouse gas emissions from power generation is considerable in provinces where electricity is generated based on coal and natural gas (such as Alberta and Saskatchewan) or fossil fuels (such as Ontario). Emissions associated with the industrial sector, which include the fossil-fuel production industries, occupy an important share of total greenhouse gas emissions in almost every province.
