Read the following passage and answer the questions by choosing the correct option (81-83). The Kyoto Protocol, which came into force on 16 February 2005, was one of the first initiatives for following the course of eco-friendly development on a global scale. Under the protocol, thirty-seven industrialized nations (called Annexure I countries) committed themselves to a reduction of the four greenhouse gases- Carbon dioxide, Methane, Sulphur hexafluorides and Nitrous oxide-and the two groups-Hydrofluorocarbons and Perfluorocarbons-produced. All the other member nations (including India) were to give a general commitment, though not as rigorous as the one given by the industrialized nations. The Annexure I countries agreed to reduce their collective emissions by 5.2 percent from the 1990 level. The Kyoto Protocol was signed by 187 countries on November 2009. India is a member of the treaty while the United States has a status of 'signed but not intending to ratify' the treaty.
