By which year are chlorofluorocarbons (CFCs) to be completely replaced by hydrochlorofluorocarbons (HCFCs)?

Chlorofluorocarbons are to be fully replaced by hydrochlorofluorocarbons by the year 2030.

HCFCs served as a lower-ozone-harm transitional replacement for CFCs.

The year 2025 is too early for the completion of this transitional replacement.

The year 2035 is later than the set target for this phase-out step.

The year 2040 is later still and does not mark this milestone.

HCFCs are themselves being phased out later in favour of HFCs and natural refrigerants.
