The CEC's map layer for Google Earth lets users explore pollution data from about 30,000 industrial facilities in North America.
With information obtained from pollutant release and transfer registers (PRTRs), the CEC has created the first seamless, North America-wide map layer connecting citizens with point-specific industrial pollutant data in Canada, Mexico and the United States.
Readers are reminded that each country has specific reporting requirements for sectors, facilities and pollutants that affect the North American picture of industrial pollution. Using and Understanding Taking Stock.
This map shows the locations of all of the facilities that reported to the North American PRTRs in 2011. The number of facilities excludes Canadian facilities that reported only releases of criteria air contaminants (CAC) to NPRI, and Mexican facilities that reported only greenhouse gases (GHG) to RETC. These two groups of pollutants are not subject to reporting under the US TRI and therefore have been excluded from the Taking Stock analysis.
Using the Google Earth mapping service’s innovative and free computer program that allows users to explore geographic data projected over satellite images and aerial photography, the CEC's map layer plots approximately 30,000 North American industrial facilities that reported to the North American PRTRs in 2011, the most recent data available from all three countries.
This Google Earth layer allows anyone in our three countries – whether in Manitoba, Mississippi, or Michoacán – to find industrial facilities located near their homes, their workplaces, or their schools. They can learn about the pollution profile of each facility, including which pollutants are generated and how the facility handles them. Users can also compare the performance of facilities in their community to similar facilities locally, nationally, and, now, across North America. The data can also be viewed in the North American Environmental Atlas in conjunction with other maps layers for North America.
