Yvo de Boer, the executive secretary of the U.N. Framework Convention on Climate Change, stated that the Kyoto Protocol is essential and will continue to exist following the climate conference in Copenhagen. De Boer emphasized the importance of the Kyoto Protocol surviving for various reasons and discussed the possibility of a second period under Kyoto and a new treaty under the convention. He mentioned that the new treaty would come into effect once a sufficient number of countries have ratified it. He stated that it took eight years for the Kyoto Protocol to come into effect, starting in 1997 when countries began signing it and finally being enforced in 2005. While some countries prefer a single treaty, the majority involved in the process are seeking a two-track outcome and want to see something in addition to the Kyoto Protocol. De Boer noted that the Kyoto Protocol already has functioning market-based mechanisms, but there are currently no provisions under the Convention for these mechanisms. If someone is interested in promoting a new treaty, there is another obstacle that individuals are not willing to recognize. According to him, the Kyoto Protocol is the sole enforceable document regarding climate change, and there is no valid rationale for discontinuing it. De Boer mentioned that considerable advancements have been achieved in certain key components that will form an agreement. It is now the opportune moment to concentrate on the broader perspective. Bangladesh previously advocated for a more robust climate agreement by extending the Kyoto Protocol that concludes in 2012. It also suggested implementing a new phase with fresh objectives for the Kyoto protocol. The Alliance of Small Island States (AOSIS) has also urged for a new agreement, known as the 'Copenhagen Protocol', to be developed using the legally-binding principles of the Kyoto Protocol.
