UN climate talks in Doha adopted Saturday a package of drafts of low-ambitious second period of Kyoto Protocol and weak commitment on climate finance after overnight negotiations on differences between developed and developing countries.

The closure of the two-week meeting in the Qatari capital was delayed for almost a whole day as diplomats from more than 190 countries press for any small progress that can be reached.

Conference President Abdullah bin Hamad al-Atiiyah said the agreement on the Kyoto Protocol would apply from 2013 till 2020. Its first commitment period expires at the end of the year.

But Russian delegate Oleg Shamanov said that Russia, along with Belarus and Ukraine, opposed the decision to extend the Kyoto Protocol beyond 2012 and noted it retained the right to appeal the president's action.

The Kyoto Protocol, the only UN plan that obliges developed nations to cut carbon emissions, is a vital step towards a new global deal to be agreed in 2015 and to enter into force from 2020.

The European Union (EU)-led group, including Australia, have pledged to join the second period of the Kyoto Protocol, while the United States, Japan, Canada and Russia, among others, insist on keeping away from the treaty despite international criticism.

However, no tougher emission reduction goals were announced by the developed countries in Doha, although they are urged to cut greenhouse gas emissions by at least 25 to 40 percent below 1990 levels by 2020.

The EU sticks to its target of 20-percent reduction, reiterating that a further step to 30 percent would require other developed countries' commitment to comparable emission reductions. Its bargaining position was weakened, as it has reportedly met its targets of 20 percent eight years ahead of time and has no plans to put more ambitious cuts on the table.

More disappointingly, the United States said it could only cut its greenhouse gas emissions by 17 percent by 2020 from 2005 levels, which corresponds to a cut of three to four percent below 1990 levels. Meanwhile, Australia proposed a 0.5-percent emission cut from 1990.

The meeting requests developed countries to submit the information by 2014 about their progress towards achieving quantified emission limitation and the potential for increasing ambition.

The EU, Australia, Japan, Liechtenstein, Monaco, Norway and Switzerland made their respective political declarations that they would not purchase the assigned amount units (AAUs) carried over from the first commitment period.

Greenhouse gas emissions are set to rise 2.6 percent this year, and are more than 50 percent higher than in 1990.

On the issue of how the developed world help developing countries respond to climate change, European nations including Britain, Germany, France, Sweden, the Netherlands and Denmark have announced to provide financial assistance worth several billion euros, although the amount is far from enough.

The developing countries complain that large promises of money from rich donors have not materialized. Developed countries have pledged a total of 30 billion U.S. dollars called "Fast Start" fund from 2010 to 2012, and a scale-up of the aid to 100 billion dollars per year by 2020.

But no agreement or timetable is turned up at the Doha talks on how to bridge the funding gap from next year, with the United States, Europe and other developed nations citing economic slowdown as the excuse for refusal to provide more.

The agreement merely "extends the work program of long-term finance for one year to the end of 2013."

The deal urged additional countries to announce climate finance pledges "when their financial circumstances permit," and encouraged developed nations to provide resources of at least the average annual level of the "Fast Start" finance period.

It indicates only 10 billion dollars of climate fund is available every year, which is only half of the amount proposed by developing countries between 2013 and 2015.

The Group 77 and China have proposed that developed countries raise 20 billion dollars per year between 2013 and 2015 for " medium-term" climate fund as the long-term finance falls into uncertainty in the wake of global economic downturn.
