Greenhouse gases are gases that contribute to global warming.
Annex A to the Kyoto Protocol lists certain greenhouse gases and emissions sources. Annex I Parties to the Kyoto Protocol are required to ensure that their emissions of the listed greenhouse gases from the listed sources do not exceed their assigned amount, calculated pursuant to their quantified emission limitation and reduction commitments under the Protocol:
The Parties included in Annex I shall, individually or jointly, ensure that their aggregate anthropogenic carbon dioxide equivalent emissions of the greenhouse gases listed in Annex A do not exceed their assigned amounts, calculated pursuant to their quantified emission limitation and reduction commitments inscribed in Annex B and in accordance with the provisions of this Article, with a view to reducing their overall emissions of such gases by at least 5 per cent below 1990 levels in the commitment period 2008 to 2012 (Kyoto Protocol, Article 3(1)).
Not all greenhouse gases are listed in the Kyoto Protocol; some are already covered by the provisions of the Montreal Protocol.
