Data Sources and Methods for the International Air Pollutant Emissions Indicators

The international air pollutant emissions indicators are part of the Canadian Environmental Sustainability Indicators (CESI) program, which provides data and information to track Canada’s performance on key environmental sustainability issues.

The international air pollutant emissions indicators track criteria air contaminant (CAC) emissions from Canada and 9 other countries. These indicators help to inform Canadians about how Canada’s emissions compare to those from other countries. The indicators report on key air pollutants that contribute to smog and acid rain and help the government to identify priorities and track/develop progress on strategies and policies put in place to reduce or control air pollution. The emissions data used for these indicators are also used to fulfill Canada’s international and domestic commitment on reporting obligations.
