National Pollutant Release Inventory (NPRI)

Preparation and Reporting

The National Pollutant Release Inventory (NPRI) is Canada's inventory of pollutant releases to air, water and soil.

Currently, over 300 substances are listed on the NPRI. Since the inventory was established in 1993, Environment Canada has implemented a number of data quality measures to ensure a high standard of accuracy and consistency.
