The targets for the first commitment period of the Kyoto Protocol cover emissions of the six main greenhouse gases, namely: Carbon dioxide (CO₂), Methane (CH₄), Nitrous oxide (N₂O), Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), and Sulphur hexafluoride (SF₆)।

The Protocol to the United Nations Framework Convention on Climate Change (the 'Kyoto Protocol') was adopted at the third session of the Conference of the Parties (COP 3) in Kyoto, Japan, on 11 December 1997. In accordance with Article 24, it was open for signature from 16 March 1998 to 15 March 1999 at United Nations Headquarters, New York. By that date, the Kyoto Protocol had received 84 signatures.

The Kyoto Protocol entered into force on 16 February 2005 in accordance with Article 23, that is on the ninetieth day after the date on which not less than 55 Parties to the Convention, incorporating Parties included in Annex I of the Convention which accounted in total for at least 55 % of the total carbon dioxide emissions for 1990 of the Parties included in Annex I, had deposited their instruments of ratification, acceptance, approval or accession.
Currently, there are 192 Parties (191 States and 1 regional economic integration organization) to the Kyoto Protocol to the UNFCCC.

The United Nations is encouraging governments to ratify as soon as they can the amendments relating to the second commitment period of the Kyoto Protocol, the international emissions reduction treaty. Ratification of the Doha Amendment to the Kyoto Protocol is a valuable part of the momentum for global climate action for the years leading up to 2020. As of 10 December 2019, 135 Parties have deposited their instrument of acceptance. Source: unfccc.int/process/the-kyoto-protocol/the-doha-amendment

At the 18th Conference of the Parties (COP18), held in Doha, Qatar, in 2012, delegates agreed to extend the Kyoto Protocol until 2020. They also reaffirmed their pledge from COP17, which had been held in Durban, South Africa, in 2011, to create a new, comprehensive, legally binding climate treaty by 2015 that would require greenhouse-gas-producing countries—including major carbon emitters not abiding by the Kyoto Protocol (such as China, India, and the United States)—to limit and reduce their emissions of carbon dioxide and other greenhouse gases. The new treaty, planned for implementation in 2020, would fully replace the Kyoto Protocol. Source: britannica.com

Kyoto Protocol, in full Kyoto Protocol to the United Nations Framework Convention on Climate Change, international treaty, named for the Japanese city in which it was adopted in December 1997, that aimed to reduce the emission of gases that contribute to global warming. In force since 2005, the protocol called for reducing the emission of six greenhouse gases in 41 countries plus the European Union to 5.2 percent below 1990 levels during the “commitment period” 2008–12.
