The Kyoto Protocol specifically relates to which one among the following issues?

The Kyoto Protocol, adopted in Kyoto, Japan, in 1997 and entered into force in 2005, is an international treaty that specifically commits its parties (developed countries) to reduce greenhouse gas (GHG) emissions. It operationalizes the United Nations Framework Convention on Climate Change (UNFCCC) by setting binding emission reduction targets for industrialized countries. Ozone layer depletion is addressed by the Montreal Protocol, biodiversity management by the Convention on Biological Diversity, and chlorofluorocarbons are regulated under the Montreal Protocol. Hence, the Kyoto Protocol specifically relates to emission reduction.
