Atmospheric carbon dioxide is not a pollutant. It is plant food.Carbon dioxide is the green gas.
Oh ferchrisake google CO2 pollution.
I've shown you proof of that fact.
BS
From skeptical science:
Is CO2 a pollutant?

What the science says...

Although it has some very important and beneficial effects, CO2 meets the legal and encyclopedic definitions of a "pollutant", and human CO2 emissions pose a threat to public health and welfare.

CO2 is not a pollutant
'To suddenly label CO2 as a "pollutant" is a disservice to a gas that has played an enormous role in the development and sustainability of all life on this wonderful Earth. Mother Earth has clearly ruled that CO2 is not a pollutant.' (Robert Balling, as quoted by Popular Technology)
Before assessing whether or not CO2 is a pollutant, we must first define the term.
What is an Air Pollutant?
The US Clean Air Act was incorporated into the United States Code of Federal Regulations, Title 42, Chapter 85. Its Title III, Section 7602(g) defines an air pollutant:
The term “air pollutant” means any air pollution agent or combination of such agents, including any physical, chemical, biological, radioactive (includingsource material, special nuclear material, and byproduct material) substance or matter which is emitted into or otherwise enters the ambient air.
Clearly this is a very broad definition. More importantly, its Title 42, Section 7408 states that the US Environmental Protection Agency (EPA) Administrator must publish a list of certain air pollutants:
"emissions of which, in his judgment, cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare"
In Massachusetts v. Environmental Protection Agency (in 2007), the US Supreme Court held that the Clean Air Act gives the EPA the authority to regulate tailpipe emissions ofgreenhouse gases. Two years after the Supreme Court ruling, in 2009 the EPA issued anendangerment finding concluding that
"greenhouse gases in the atmosphere may reasonably be anticipated both to endanger public health and to endanger public welfare....The major assessments by the U.S. Global Climate Research Program (USGCRP), the Intergovernmental Panel on Climate Change (IPCC), and the National Research Council (NRC) serve as the primary scientific basis supporting the Administrator’s endangerment finding."Greenhouse gases including CO2 unquestionably fit the Clean Air Act's broad definition of "air pollutants," and must be listed and regulated by the EPA if it can be determined that they endanger public heath and/or welfare.
Alternatively, the definition of "pollution" from Encyclopedia Brittanica is:
"the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form."
Thus legally in the USA, CO2 is an air pollutant which must be regulated if it may endanger publich health or welfare. And according to the encyclopedic definition, CO2 is a pollutant unless our emissions can be stored "harmlessly."
Is Increasing CO2 Dangerous or Harmless?
Humans are Increasing Atmospheric CO2 Concentrations
Humans have increased the amount of CO2 in the atmosphere by 40% over the past 150 years, primarily through the combustion of fossil fuels.
