What year does the Montreal Protocol phase out HCFCs?

The Montreal Protocol, which is an international treaty designed to phase out substances that deplete the ozone layer, includes specific timelines for phasing out hydrochlorofluorocarbons (HCFCs). According to the terms of the amendment made to the protocol, developed countries are required to completely phase out HCFCs by the year 2020, while developing countries were given a longer timeline, with a requirement to phase out HCFCs by 2030. This agreement reflects the commitment of countries to reduce the environmental impact of substances that harm the ozone layer and contribute to climate change. Therefore, the correct answer is associated with the timeline set for developing nations, marking 2030 as the pivotal year for phasing out HCFCs in those jurisdictions.
