SCOTUS cited CAA as clearly defining what a pollutant is and determined that CO2 was therefor a pollutant removing that argument.
It was the Supreme Court, not the EPA, that decided in 2007 that carbon dioxide meets the definition of pollutant under the Clean Air Act—a law enacted by a democratically elected Congress and signed by a democratically elected President, George H.W. Bush.
In 1989, coal companies and the Edison Electric Institute hired Temple Barker and Sloane, a pro-industry research organization, to conduct an economic analysis of the effects of a cap & trade system on sulphur dioxide (SO2), the main pollutant that causes acid rain.
When we burn fossil fuel, excess carbon dioxide (CO2), the chief global warming pollutant, is released to the atmosphere.
The main pollutant was suspended particulate matter, which is usually attributed to coal burning and automotive exhaust.
The display of the empirical evidence on the local pollutant is intended to enable and change typical lay-expert communication patterns, by raising the standards of evidence, or at least changing who produces this evidence.
