Air Pollutant Emission Inventory - Online Data Search
Welcome to the Air Pollutant Emission Inventory (APEI) data search. Use this query tool to obtain information on national, provincial and territorial air emission summaries for key air pollutants, heavy metals and persistent organic pollutants from anthropogenic emission sources. Air emissions of these pollutants are available nationally, provincially and territorially from 1990 to present.
In addition, we recommend accessing APEI data tables through the Government of Canada’s open data website.
To search detailed information on pollutant releases (to air, water and land), disposals and transfers for recycling reported by facilities to the National Pollutant Release Inventory (NPRI), visit the related site: National Pollutant Release Inventory Online Data Search - Facility-reported Data.
To search Canada’s legislated, publicly accessible inventory of facility-reported greenhouse gas data and information, visit the related site: Greenhouse Gas Emissions Reporting Program Data - Facility Data Search.
Data available on this website are current as of November 4, 2016. Ongoing improvements or future corrections may result in updates. As part of the quality control process, we conduct a number of data checks to ensure the data is of the highest possible quality.
