The 'Kyoto Protocol' is an international treaty that commits State parties to reduction in

The correct answer is B, greenhouse gases emission. The Kyoto Protocol, adopted at Kyoto, Japan on 11 December 1997 under the UN Framework Convention on Climate Change, was the first treaty to set binding targets for cutting emissions. It came into force on 16 February 2005 and asked industrialised countries to cut their greenhouse gas emissions by an average of about 5 per cent below 1990 levels during 2008 to 2012. It covered six gases, including carbon dioxide, methane and nitrous oxide, and created market tools such as the Clean Development Mechanism, which let projects in countries like India earn carbon credits. India ratified it in 2002 but, as a developing country, had no binding target. A is wrong, because cutting poverty is the aim of goals such as the UN Sustainable Development Goals, not Kyoto. C is wrong, because nuclear arms are dealt with by treaties like the Non-Proliferation Treaty of 1968. D is wrong, because farm subsidies fall under the WTO's Agreement on Agriculture. Exam tip: Kyoto 1997, in force 2005, binding cuts for rich nations; Paris 2015, pledges from all nations.
