Who are the members of Kyoto protocol?

The Kyoto Protocol is an international treaty that commits its parties to reduce greenhouse gas emissions, based on the premise that global warming exists and human-made CO2 emissions have caused it. The original members include 37 industrialized countries and the European Union, which are required to reduce their emissions under the treaty. Notable signatories include the United States (which later withdrew), Canada, Japan, and many European nations. Developing countries, such as China and India, were not bound by the same emission reduction targets but were encouraged to participate in future climate agreements.
