DURBAN, South Africa - A U.N. climate conference reached a hard-fought agreement Sunday on a complex and far-reaching program meant to set a new course for the global fight against climate change for the coming decades.
The 194-party conference agreed to start negotiations on a new accord that would put all countries under the same legal regime enforcing commitments to control greenhouse gases. It would take effect by 2020 at the latest.
The deal also set up the bodies that will collect, govern and distribute tens of billions of dollars a year for poor countries. Other documents in the package lay out rules for monitoring and verifying emissions reductions, protecting forests, transferring clean technologies to developing countries and scores of technical issues.
Currently, only industrial countries have legally binding emissions targets under the 1997 Kyoto Protocol. Those commitments expire next year, but they will be extended for another five years under the accord adopted Sunday a key demand by developing countries seeking to preserve the only existing treaty regulating carbon emissions.
The proposed Durban Platform offered answers to problems that have bedeviled global warming negotiations for years about sharing the responsibility for controlling carbon emissions and helping the world's poorest and most climate-vulnerable nations cope with changing forces of nature.
The United States was a reluctant supporter, concerned about agreeing to join an international climate system that likely would find much opposition in the U.S. Congress.
"This is a very significant package. None of us likes everything in it. Believe me, there is plenty the United States is not thrilled about," said U.S. climate envoy Todd Stern. But the package captured important advances that would be undone if it is rejected, he told the delegates.
The deal's language left some analysts warning that the wording left huge loopholes for countries to avoid tying their emissions to legal constraints, and noted that there was no mention of penalties. "They haven't reached a real deal," said Samantha Smith, of WWF International. "They watered things down so everyone could get on board."
Environmentalists criticized the package as did many developing countries in the debate for failing to address what they called the most urgent issue, to move faster and deeper in cutting carbon emissions.
"The good news is we avoided a train wreck," said Alden Meyer, recalling predictions a few days ago of a likely failure. "The bad news is that we did very little here to affect the emissions curve."
Scientists say that unless those emissions chiefly carbon dioxide from power generation and industry level out and reverse within a few years, the Earth will be set on a possibly irreversible path of rising temperatures that lead to ever greater climate catastrophes.
Sunday's breakthrough capped 13 days of hectic negotiations that ran a day and a half over schedule, including two round-the-clock days that left negotiators bleary-eyed and stumbling with words. Delegates were seen nodding off in the final plenary session, despite the high drama, barely constrained emotions and uncertainty whether the talks would end in triumph or total collapse.
The nearly fatal issue involved the legal nature of the accord that will govern carbon emissions by the turn of the next decade.
A plan put forward by the European Union sought strong language that would bind all countries equally to carry out their emissions commitments.
India led the objectors, saying it wanted a less rigorous option. Environment Minister Jayanthi Natarajan argued that the EU proposal undermined the 20-year-old principle that developing countries have less responsibility than industrial nations that caused the global warming problem through 200 years of pollution.
"The equity of burden-sharing cannot be shifted," she said in angry tones.
Chinese negotiator Xie Zhenhua gave heated support for the Indians, saying the industrial nations have not lived up to their promises while China and other developing countries had launched ambitious green programs.
"We are doing whatever we should do. We are doing things you are not doing. What qualifies you to say things like this," he said, raising his voice and waving his arm.
The debate ran past midnight and grew increasingly tense as speakers lined up almost evenly on one side or the other. Conference president Maite Nkoana-Mashabane, who is South Africa's foreign minister, called a recess and told the EU and Indian delegates to put their heads together and come up with a compromise formula.
Coming after weeks of unsuccessful effort to resolve the issue, Nkoana-Mashabane gave Natarajan and European Commissioner Connie Hedegaard 10 minutes to find a solution, with hundreds of delegates milling around them.
They needed 50 minutes.
The package gave new life to the 1997 Kyoto Protocol, whose carbon emissions targets expire next year and apply only to industrial countries. A separate document obliges major developing nations like China and India, excluded under Kyoto, to accept legally binding emissions targets in the future.
Together, the two documents overhaul a system designed 20 years ago that divide the world into a handful of wealthy countries facing legal obligations to reduce emissions, and the rest of the world which could undertake voluntary efforts to control carbon.
The European Union, the primary bloc falling under the Kyoto Protocol's reduction commitments, said an extension of its targets was conditional on major developing countries also accepting limits with the same legal accountability. The 20th century division of the globe into two unequal parts was invalid in today's world, the EU said.
The difficult clause in the documents called on countries to complete negotiations within three years on "a protocol, another legal instrument, or a legal outcome" that would succeed the Kyoto Protocol. It would need about five years for ratification.
But the EU objected to the late addition of the phrase "legal outcome," which it said would allow countries to wriggle out of commitments. The final compromise, reached at 3:30 a.m., changed the final option to "an agreed outcome with legal force."
