Environmental Indicators
Canadian Environmental Sustainability Indicators (CESI) measure the progress of the Federal Sustainable Development Strategy, report to Canadians on the state of the environment, and describe Canada’s progress on key environmental sustainability issues. The indicators, built on rigorous methodology, are added and updated as new, high quality data become available.
