![]() Hydrochlorofluorocarbons are considered interim replacements for CFCs. Although more ozone-friendly than CFCs, they still destroy some ozone. Hydrofluorocarbons and fluorocarbons are ozone-safe, but some have high global warming potential. In some cases, ammonia (NH3), butane (C4H10), or pentane (C5H12) can be suitable substitutes for CFCs. Photo: Courtesy of GSFC/NASA. Although there has
been much progress, replacements for CFCs that are neutral in their effects on the
environment are still needed.
