International Comparison of Air Pollutant Emissions

Access PDF (743 KB)

Canada's air pollutant emissionsFootnote [1] are compared with those of member countriesFootnote [2] of the Organisation for Economic Co-operation and Development (OECD) for 2003 and 2013, with a focus on the top 10 emitting countries for each air pollutant examined. The air pollutant emissions and ratio of emissions to gross domestic product (GDP)Footnote [3] are provided for sulphur oxides (SOX), nitrogen oxides (NOX), volatile organic compounds (VOCs), carbon monoxide (CO) and fine particulate matter (PM2.5).

Sulphur oxides

Although Canada's SOX emissions declined by 47% in 2013 from 2003 levels, Canada ranked fourth in SOX emissions among OECD member countries in 2013 behind the United States, Turkey and Australia and also had the fourth largest ratio of emissions to GDP among the top 10 emitting OECD member countries.

Bar Chart

Long description

The two bar charts compare Canada's 2003 and 2013 sulphur oxide emissions in kilotonnes (left chart), and emissions intensity in tonnes per million U.S. dollars of gross domestic product (right chart) with those of nine top emitting countries members of the Organisation for Economic Co-operation and Development with available data for both reported years. For sulphur oxide emissions and ratio of emissions to gross domestic product, these nine countries are: United States, Turkey, Australia, Poland, Japan, Germany, United Kingdom, Spain and France.

Fine particulate matter

In 2013, Canada's PM2.5 emissions were 28% higher than 2003 emissions. Canada ranked second for total PM2.5 emissions among the OECD member countries behind the United States. However, in terms of the ratio of emissions to GDP, Canada ranked highest for PM2.5 among these countries. It is important to note that the United States and Canada are including open sourcesFootnote [4] such as dust from roads, agriculture and construction. These sources are not always reported by the other OECD member countries.
