Taking Stock Online: North American industrial pollution

A Pollutant Release and Transfer Register (PRTR) provides annual data on the amounts of pollutants released from a facility to the air, water and land and injected underground, as well as transferred off-site for recycling, treatment or disposal. The CEC’s North American PRTR (NAPRTR) project promotes public access to PRTR data to improve understanding of the sources and management of pollutants of common concern. The NAPRTR project compiles and disseminates data reported by facilities to the three national PRTRs. The data used in Taking Stock are obtained from Canada’s National Pollutant Release Inventory (NPRI) Mexico's Registro de Emisiones y Transferencia de Contaminantes (RETC), and the UnitedStates' Toxics Release Inventory (TRI). Efforts are focused on adding value to the data through their integration, analysis and dissemination. Taking Stock Online is a portal for users to explore North American PRTR data through several interactive tools, or through comprehensive reports.

TAKING STOCK REPORT

In our last report, Taking Stock, Vol. 13 (published in April 2011), we analyzed data for 2006, the most recent available data from the three countries at the time of writing. The report features an analysis on pollutant releases to surface waters. Since then, the North American PRTR programs have achieved comparable data publication schedules and the CEC has thus integrated four additional years of data, through 2010.

Click here to access a brief summary of 2009 data, along with some observations about changes in reporting since 2006. Additional data up to and including 2010 and analyses of reporting changes over time will be provided in the full Taking Stock report to be published later this year.
