Single year data tables by facility – releases, transfers and disposals

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling.

This file contains the most commonly used NPRI data fields, within a simplified tabular format, including all facility-reported pollutant releases, disposals and transfers for recycling for a given year, listed by facility and substance.

There are important factors that should be considered prior to the use and interpretation of NPRI data.
