National Pollutant Release Inventory
The National Pollutant Release Inventory (NPRI), established in 1992, is the national Pollutant Release and Transfer Register of Canada. The publicly-accessible inventory is used to track and catalogue the release of pollutants, their disposal, or their transfer to recycling and other facilities across the country. All pollutants released to air, water, or land are tracked.
Facilities which meet reporting requirements are required to report to the NPRI under the Canadian Environmental Protection Act, 1999 (CEPA 1999). Over 300 substances are listed on the NPRI, and over 8,000 facilities annually report information on their pollutant releases and transfers to Environment Canada.
NPRI data is available through an on-line Query search, downloadable Microsoft Access (mdb) format datasets, and downloadable map layers for use with Google Earth (which were the first Google Earth map layers to be published by the Government of Canada).
