The global climate change conference in Bali went into extra time on Friday as negotiators are yet to decide on the emission cut binding.
The 12-day conference of parties to the UN Framework Convention on Climate Change was scheduled to conclude on Friday.
The Indian delegation to the conference is led by the science and technology minister Kapil Sibal.
The conference reached a point of deadlock on the issue of how ambitious the goal should be in the future cuts in emission of gases responsible for global warming.
The exemption of fast-growing economies like India and China from mandatory emission cuts under the Kyoto Protocol invited complaint from the US. The European Union suggested a goal for reducing emissions by between 25% and 40% below 1990 levels by the year 2020. The US differed with the EU proposal.
However, UN climate chief Yvo de Boer said ?I hope the matter would be resolved by night.? The talks, which opened here on December 3, were designed to set a framework for moving ahead once the Kyoto Protocol?s obligations expire in 2012.
The conference has, however, agreed to tackle greenhouse gas emissions from deforestation. It has been hailed as a sign of developing nations? commitment to fighting global warming. This might eventually allow poor but forested nations to turn conservation into a tradable commodity, with the potential to earn billions of dollars selling carbon credits.
