What can be done to prevent ozone depletion?

The most common association with man-made gases from the 20th century that prevented ozone (O3) from being created is that of CFCs, which were primarily used in aerosol spray cans and as refrigerants in freezers, refrigerators, and air conditioning units.

To prevent ozone depletion, it is essential to reduce the emission of ozone-depleting substances (ODS) such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, and methyl bromide. This can be achieved through the implementation of international agreements like the Montreal Protocol, which regulates the production and consumption of ODS. Additionally, transitioning to ozone-friendly alternatives in industries, such as using hydrofluorocarbons (HFCs) instead of CFCs and HCFCs, can help mitigate ozone depletion. Public awareness campaigns and education on the importance of protecting the ozone layer can also encourage individuals to make environmentally conscious choices and reduce their use of ODS-containing products.
