Black = Annex I Parties who have agreed to reduce their GHG emissions below their individual base year levels (see definition in this article)
Grey = Annex I Parties who have agreed to cap their GHG emissions at their base year levels
Pale grey = Non-Annex I Parties who are not obligated by caps or Annex I Parties with an emissions cap that allows their emissions to expand above their base year levels or countries that have not ratified the Kyoto Protocol

For specific emission reduction commitments of Annex I Parties, see the section of the article on 2012 emission targets and "flexible mechanisms".

The European Union as a whole has in accordance with the Kyoto Protocol committed itself to an 8% reduction. However, many member states (such as Greece, Spain, Ireland and Sweden) have not committed themselves to any reduction while France has committed itself not to expand its emissions (0% reduction).]]
