Environment Canada's National Pollutant Release Inventory (NPRI)
 NPRI Home

Welcome to Canada's
National Pollutant Release Inventory (NPRI)

We're improving our Website,

The NPRI website is being redeveloped to serve you better and to implement the updated Government of Canada Common Look and Feel Standards for the Internet. The new website will be available shortly. If you have any questions, please contact the NPRI.

The NPRI is Canada's legislated, publicly-accessible inventory of pollutants released, disposed of and sent for recycling by facilities across the country. Industrial, institutional and commercial facilities which meet NPRI reporting requirements are required to report under the Canadian Environmental Protection Act, 1999 (CEPA 1999).

Information collected by the NPRI is included in the national inventory of Criteria Air Contaminant (CAC) emissions. This inventory also includes emission estimates for facilities that are not required to report to the NPRI, and non-facility emission sources such as forest fires and motor vehicles.
