2007 National Pollutant Release Inventory (NPRI) Reviewed Facility Data Release

Smoke Stacks As per the established process for the release of data reported by facilities to the NPRI, Environment Canada published preliminary 2007 NPRI facility data in the NPRI Online Data Search on June 21, 2008. Departmental staff then reviewed reported data for suspected inaccuracies and reporting errors, and contacted facilities, as necessary, to verify their reports, ultimately to produce a reviewed 2007 NPRI dataset.

Reviewed NPRI facility data for 2007 is now available. NPRI 2007 Highlights, a 2007 Facility Data Summary, resources for accessing NPRI facility data in various formats, and frequently asked questions about the NPRI are available below:

NPRI 2007 Highlights

Over 8,500 industrial, commercial and other facilities reported to the NPRI for 2007. Two thirds were located in Alberta and Ontario.
The NPRI program continues to evolve to provide more comprehensive information on pollution in Canada:
- Nine substances were added to the NPRI list for 2007, bringing the total of uniquely-listed substances or substance groups to 347, compared with 178 when the NPRI program was established.
- The reporting exemption for emissions of particulate matter from on-site vehicle travel on unpaved roads (a significant contributor to local air quality challenges in certain areas) was removed for 2007. Reporting exemptions for oil & gas extraction, mining, and pits & quarries were also removed over the past five years, providing expanded tracking of pollution in Canada.
Total pollutant releases reported to the NPRI decreased 4% in the five year period between 2003 and 2007, due primarily to decreases from facilities in the electricity generation and primary metal industries. However, reported pollutant releases from certain facilities across the country have increased, such as many in the oil & gas sector due to increased production.
