Taking Stock
Taking Stock is an annual report that analyzes data reported to the pollutant release and transfer registers (PRTRs) of Canada, Mexico and the United States to present a North American picture of industrial pollution. The data are reported by industrial facilities to the three North American PRTRs:
- Canada's National Pollutant Release Inventory (NPRI)
- US Toxics Release Inventory (TRI)
- Mexico's Registro de Emisiones y Transferencia de Contaminantes (RETC)
Taking Stock Online, the CEC's integrated and searchable database, allows users the opportunity to compare and analyze North American releases and transfers of pollutants by location, substance, facility and type of release or transfer, and to map the results.
