Chlorofluorocarbons (CFCs) : A group of inert chemical used in many industrial and everyday processes such as our refrigerators that are not broken down at lower atmospheric levels and rise to the upper levels, destroying ozone. They are water vapor, carbon dioxide, methane, nitrous oxide, ozone, CFCs, and hydrofluorocarbons.
The category of “volatile chemicals” includes a number of different chemicals that cause ozone pollution. There is also precedent for combining multiple pollutants that have similar effects into a single category. It will need a reasoned explanation for why to split them up.
