Data Sources and Methods for the Air Pollutant Emissions Indicators

Introduction

The 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 air pollutant emissions indicators track the emissions of key air pollutants that contribute to smog and acid rain in Canada, and that can adversely affect the health of Canadians and the environment. These indicators inform Canadians on the levels of air pollutants that are emitted in Canada. The air pollutant emissions indicators also help the government to identify priorities, track progress, and develop strategies and policies for reducing or controlling air pollution.
