Environmental groups say they will prevent the Mexican government from making good on its intention to release local industries from having to measure eight of the greenhouse gases they emit. “We are protecting society from this move, which runs against transparency and the health of the population,” Tania Mijares, of the Mexican Center for Environmental Law, one of the eight groups that denounced the government plans, told Tierramérica.

In September, the Environment Secretariat requested that the planned Registry of Emissions and Transference of Pollutants exclude carbon dioxide, nitrogen dioxide, sulfur hexafluoride, hydrobromofluorocarbons, hydrofluorocarbons, methane, nitrous oxide and perfluorocarbons.

The registry, which has been in the works for more than a decade and could begin operating in 2007, will be part of the reports that Mexican industries present about their emissions.
