The pollutants I was referring to are the type of toxic air pollutants that are regulated by the EPA under the Clean Air Act and its predecessors.

Hazardous air pollutants, also known as toxic air pollutants or air toxics, are those pollutants that cause or may cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental and ecological effects. EPA is required to control 187 hazardous air pollutants. Examples of toxic air pollutants include benzene, which is found in gasoline; perchlorethlyene, which is emitted from some dry cleaning facilities; and methylene chloride, which is used as a solvent and paint stripper by a number of industries. Through appropriate rulemaking, the Clean Air Act list can be modified.

My key point is that carbon dioxide is not in that list and really doesn’t meet the criteria for being a toxic pollutant. Plants breathe it. It occurs naturally. It was not on the list of pollutants to be regulated under the Clean Air Act. Toxic pollutants are poisonous and even small concentrations can cause birth defects, cancer, and death. There is widespread support for the regulation of toxic pollutants. Those regulations do not apply to CO2. If they did, you would become illegal as a pollution emitter. What do you think it is you breathe out?
