The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The International comparison: air pollutant emissions in selected countries indicator provides emissions and emissions intensity for member countries of the Organisation for Economic Co-operation and Development. The emissions of 5 pollutants are reported: sulphur oxides, nitrogen oxides, carbon monoxide, volatile organic compounds and fine particulate matter. This indicator helps to inform Canadians about how Canada's emissions compare to those of other countries. The indicator reports on key air pollutants that contribute to smog and acid rain and help the government to identify priorities, track progress, and develop strategies and policies for reducing or controlling air pollution. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for the data sources and details on how the data were collected and how the indicator was calculated.
