Maruf Mallick, bdnews24.com's environment correspondent in Copenhagen, reported that Yvo de Boer, the executive secretary of the U.N. Framework Convention on Climate Change, expressed confidence that the Kyoto Protocol will endure 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 as well as a new treaty under the convention being established. He stated that it took eight years from when countries began signing the Kyoto Protocol in 1997 to when it was enforced in 2005. While some countries prefer a single treaty, most countries involved in the process are in favor of a two-track outcome, wanting additional measures alongside the Kyoto Protocol. De Boer noted that the Kyoto Protocol already includes functioning market-based mechanisms, but there are currently no provisions for additional mechanisms under the Convention. If someone is interested in proposing a new treaty, there is a gap that many people are unwilling to overlook. The Kyoto Protocol is the sole legally binding document related to climate change, and there is no valid reason to discard it, according to him. De Boer mentioned that substantial advancements have been achieved on key components that will form an agreement. "It is crucial now to concentrate on the broader perspective." Bangladesh previously called for a more robust climate agreement by extending the Kyoto Protocol, which ends in 2012. It also suggested a new stage with fresh targets for the Kyoto Protocol. The Alliance of Small Island States (AOSIS) is advocating for a new agreement, the 'Copenhagen Protocol', which would be modeled after the Kyoto Protocol, a legally-binding document.
