The Kyoto Protocol is a protocol of the United Nations Framework Convention on Climate Change, and an international agreement that seeks to reduce the emissions of six greenhouse gases that generate global warming. The gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFC), perfluorocarbons (PFC) and sulfur hexafluoride (SF6).

The protocol agreed to a reduction of at least 5% of the emissions of these gases in 2008-2012 compared to 1990 emissions. This agreement does not imply that each country committed to reduce its emissions of regulated gases in a 5% as a minimum, but this is a percentage corresponding to a global commitment and each country subscribing to the protocol had its own commitments to reduce emissions.
