Exports represented nearly half of the industrial emissions of greenhouse gases in Canada in 2002, the largest single share of emissions from a demand perspective, according to a new Statistics Canada study.
Typically, emissions are reported from a supply perspective, showing how much pollutant is produced and by whom. While this supply perspective is important, it is also useful to look at emissions from a demand perspective. This shows how the consumption of goods and services for different purposes (household use, for example) drives the industrial production of greenhouse gas emissions.
The study found that between 1990 and 2002, total greenhouse gas emissions from industrial sources increased 18.4 percent to 573,843 kilotonnes. Exports accounted for the vast majority of this increase.
During this period, greenhouse gas emissions from the production of goods and services sent to international markets surged 49.9 percent to 264,358 kilotonnes.
