What is the EPA's current position regarding the use of CFCs?

The correct response highlights the Environmental Protection Agency's commitment to phasing out chlorofluorocarbons (CFCs) due to their significant impact on ozone depletion. CFCs are known to release chlorine atoms in the stratosphere, which leads to the breakdown of ozone molecules that protect the Earth from harmful ultraviolet (UV) radiation. Recognizing this environmental threat, international agreements such as the Montreal Protocol have been established to phase out the production and consumption of ozone-depleting substances, including CFCs.

As a result, CFCs are not only restricted but are being systematically eliminated from use in refrigeration, air conditioning, and aerosol propellants. This aligns with the global effort to mitigate environmental damage and protect the ozone layer, making the phase-out of CFCs a priority in environmental policy.
