- Kyoto Protocol
- under the Climate Change Convention (UNFCCC),
adopted at COP-3 on 11 December 1997).
The Kyoto Protocol commits Annex I Parties to
individual, legally binding targets to limit or reduce their greenhouse
gas emissions, adding up a total cut of at least 5% from 1990 levels in
the period 2008-2012.
The Protocol also establishes three innovative 'mechanisms', known as
joint implementation, emissions trading and the clean development
mechanism, which are designed to help Annex I Parties reduce the costs of
meeting their emissions targets.
The Kyoto Protocol was open for signature between 16 March 1998 and 15
March 1999. During that period, 84 countries signed the Protocol,
including all but two Annex I Parties. In order to enter into force, the
Protocol must be ratified (or adopted, approved, or acceded to) by 50
Parties to the Convention. As of 29 July 2004, 124
ratified or acceded to the Kyoto Protocol; Belgium has signed the
Protocol on 29 April 1998 and has ratified it on 31 May 2002.
