Database – all data for all years

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 database contains the full NPRI dataset from 1993 to the current reporting year. To help you navigate, a Microsoft Word file provides information on the database’s structure and schema.

The database is available in Microsoft Access format (accdb). The data are in normalized or “list” format and are optimized for pivot table analyses.
