The ozone hole can be reduced by the following measures:

• Buy air-conditioning and refrigeration equipment that do not use HCFCs as a refrigerant.
• Buy aerosol products that do not use HCFCs or CFCs as propellants.
• Conduct regular inspection and maintenance of air-conditioning and refrigeration appliances to prevent and minimize refrigerant leakage.
• When motor vehicle air-conditioners need servicing, make sure that the refrigerants are properly recovered and recycled instead of being vented to the atmosphere.
• Dispose of pre-1995 refrigerators, freezers, and air conditioning units properly. These devices use chlorofluorocarbons to function, so leaks release the chemical into the atmosphere.
