Ozone is produced naturally in the stratosphere. But  "good" ozone is  referred to as ozone-depleting substances (ODS), including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, and methyl chloroform. These were are sometimes still used in coolants, foaming agents, fire extinguishers, solvents, pesticides, and aerosol propellants.
