2010 NPRI Reviewed Facility Data Release


SmokestacksOn March 27, 2012, Environment Canada published reviewed 2010 data collected from facilities through the National Pollutant Release Inventory (NPRI), following the completion of the Department’s annual NPRI data quality control process. Preliminary data were published in October 2011.

There are a number of important factors to consider when using and interpreting NPRI data. For more information, please review the Considerations when using NPRI data page.

The reviewed data are available in multiple formats, including an online data search application, map layers for use with Google EarthTM, and downloadable datasets.

NPRI 2010 Facility Data Highlights:

  • For the 2010 reporting year, 346 substances or substance groups were listed on the NPRI, and 8096 facilities submitted reports on the substances that they released, disposed of, or sent to other facilities for recycling.
  • Total releases of pollutants to air, water and land[1] reported to the NPRI fell 19% between 2006-2010, driven by reductions from primary metal smelters and other manufacturing facilities, and fossil fuel electricity-generating stations.
  • Overall decreases were partially offset by increases reported by facilities in some sectors, such as oil sands operations related to increased production, and wastewater treatment facilities from increases in wastewater flow related to population growth.
