National Pollutant Release Inventory and Air Pollutant Emission Summaries and Trends Downloadable Datasets

There are a number of factors to keep in mind when using and interpreting National Pollutant Release Inventory (NPRI) data. For example, changes to the list of reported substances over time are important to understand when conducting trend analysis. Please review the Considerations when using NPRIdata.

NPRIdata are available in various downloadable formats, in addition to the online search tools:

  1. Facility Data
    Information on pollutant releases, disposals and transfers for recycling reported by facilities, and their latitude and longitude coordinates. Downloadable formats include databases, spreadsheets and map layers, with the data also available through the online search tool for facility-reported data.

  2. Air Pollutant Emission Summaries and Trends
    Summaries and trends for key air pollutantsbased on data reported by facilities combined with estimates for other emission sources such as motor vehicles, residential heating and agricultural activities. This data is downloadable in spreadsheet format, as well as being available through the online search tool for air pollutant emissions.

1. Facility Data

A) Information on pollutant releases, disposals and transfers for recycling reported to the NPRI by industrial and other facilities

This data is also available through the online search tool for facility-reported data, for those users that may have difficulty accessing the data using the downloadable database, spreadsheet and map layer files. Note that facility-reported data within these files is available in the official language of submission.

NPRI is transitioning toward more accessible formats for publication. As a result Environment Canada is planning to replace the Microsoft Access database format with a series of non-proprietary data tables (ex. CSV) starting in 2015. If you have any questions on the new formats or comments on the transition please contact NPRI.

2. Air Pollutant Emission Summaries and Trends

Summaries and trends for key air pollutants are based on data reported by facilities combined with estimates for other emission sources such as motor vehicles, residential heating and agricultural activities.

The national, provincial and territorial  data is also available through the online search tool for air pollutant emissions data.
