Our Work on Tracking Pollutant Releases and Transfers in North America

Along with the energy, materials and items they produce, North American industries generate pollutants that must be managed to protect human health and the environment. Each year, facilities report the amounts of substances they release to air, water, or land, send to disposal, or transfer for recycling or other management. We integrate and analyze data reported to the Canadian, Mexican and US PRTRs and make them available to the public through Taking Stock Online and the Taking Stock report series.
