The National Pollutant Release Inventory (NPRI) is Canada's legislated, publicly-accessible inventory of pollutants released, disposed of and recycled by industrial, institutional and commercial facilities across the country.

It is used for identifying and monitoring sources of pollution and developing indicators for air, land, and water quality.

Under this legislation, the University provides Environment Canada with an annual report of contaminants released to air (carbon monoxide, oxide of nitrogen, and particulate matter) by UBC Utilities.

For further contaminant details as reported by UBC under the NPRI see the table, Contaminants Released to Air by UBC in 2010.

For more information on criteria air contaminants, see also Criteria Air Contaminants and Related Pollutants (Environment Canada).
