Every year, the Commission for Environmental Cooperation (CEC) compares releases and transfers from facilities in Canada and the US. The analysis is based on data provided to governments from facilities.
For the first time this year, the report includes data from facilities in Mexico. It’s the first year that facilities in Mexico reported their pollution to the government.

There’s some good news in the report. Releases by facilities in Canada and the US decreased by 15 per cent between 1998 and 2004.

But, not all facilities were responsible for this decline. In fact, the report found that medium and small facilities, as a group, actually increased their releases over that time period. At the same time, very large facilities, as a group, decreased their releases. Facilities were divided into size categories based on the amount of releases and transfers they reported in 1998.
