The correct answer is Option (3) → Montreal Protocol – a ban on CFC compounds and other ozone depleting chemicals
The Montreal Protocol deals with ozone depletion. The Kyoto conference deals with global warming.
Option (1) Montreal Protocol – reductions in emissions of greenhouse gases by industrialised nations — Incorrect. Cutting greenhouse gas emissions by industrialised nations was the aim of the Kyoto agreement.
Option (2) UN Conference on Climate Change at Kyoto (1997) – a ban on chlorofluorocarbon (CFC) compounds — Incorrect. The ban on CFCs came from the Montreal Protocol.
Option (3) Montreal Protocol – a ban on CFC compounds and other ozone depleting chemicals — Correct. Worry over falling ozone led to the Montreal Protocol, which banned CFCs and other ozone depleting chemicals.

NCERT (2026-27): “Box 7.2: Ozone Depletion … Since the ozone layer prevents most harmful wavelengths of ultraviolet light from passing through the Earth’s atmosphere, observed and projected decreases in ozone have generated worldwide concern. This led to the adoption of the Montreal Protocol banning the use of chlorofluorocarbon (CFC) compounds, as well as other ozone depleting chemicals such as carbon tetrachloride, trichloroethane (also known as methyl chloroform), and bromine compounds known as halons.” “Box 7.1: Global Warming … A UN Conference on Climate Change, held in Kyoto, Japan, in 1997, resulted in an international agreement to fight global warming which called for reductions in emissions of greenhouse gases by industrialised nations.” “7.4 Sustainable Development … In 2015, the UN formulated 17 Sustainable Development Goals (SDGs) intended to be achieved by the year 2030. …” |
