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

Established in 1992, the NPRI currently collects information on the release, disposal and transfer of more than 320 substances.

Releases are direct discharges of pollutants into the environment (air, water, land).

Disposals manage substances and limit their release. Disposals include landfill, land application and underground injection and can be done at the facility (on-site) or elsewhere (off-site).

Transfers send substances elsewhere for recycling, energy recovery or for treatment before final disposal.

There are important factors that should be considered prior to the use and interpretation of NPRI data. Additional information is available on the NPRI web site.
