This report is intended to serve as an information source for governments, industry and communities in analyzing such data from a North American perspective and for identifying opportunities for pollution reduction. The analyses are based on 1995–2002 data from the US Toxics Release Inventory (TRI) and the Canadian National Pollutant Release Inventory (NPRI).
Results from 2002, trends over the eight years from 1995 to 2002, and from 1998 to 2002 are presented here. As data become available from the Mexican (voluntary for the 2002 reporting year), they will be included in future reports. This year, for the first time, information on criteria air contaminants from Canada, Mexico and the United States is included, since NPRI has added reporting on criteria air contaminants starting with the 2002 reporting year. Taking Stock 2002 is the ninth in the CEC’s Taking Stock series on sources, releases and transfers of industrial pollutants in North America.
