LE BOURGET, France — High-stakes climate talks outside Paris will not end Friday as planned but will continue at least one more day as diplomats try to overcome disagreements over how — or even whether — to share the costs of fighting climate change and shift to clean energy on a global scale.
Negotiators from more than 190 countries are trying to do something that's never been done: reach a deal for all countries to reduce man-made carbon emissions and cooperate to adapt to rising seas and increasingly extreme weather caused by human activity. Secretary of State John Kerry zipped in and out of negotiation rooms as delegates broke into smaller groups overnight to iron out their differences.
After all-night talks wrapped up at nearly 6 a.m. local time (midnight ET), French Foreign Minister Laurent Fabius said he is aiming for a final draft Saturday.
The two-week talks, the culmination of years of U.N.-led efforts for a long-term climate deal, had been scheduled to wrap up Friday. The U.N. talks often run past deadline, given the complexity and sensitivity of each word in an international agreement.
"I will not present the text Friday evening, as I had thought, but Saturday morning," Fabius said on BFM television. "There is still work to do ... Things are going in the right direction."
Fabius said he wanted to consult with various negotiating blocs so that "this is really a text ... that comes from everyone."
He added: "This represents all of the countries in the world and it's completely normal to take a bit of time, so we will shift it."
Negotiators from China, the U.S. and other nations are haggling over how to share the burden of fighting climate change and paying for a trillion-dollar transition to clean energy.
Earlier, some delegates said a new draft presented late Thursday by Fabius allowed rich nations to shift the responsibility of fighting global warming to the developing world.
"We are going backwards," said Gurdial Singh Nijar of Malaysia, the head of a bloc of hardline countries that also includes India, China and Saudi Arabia.
They have put up the fiercest resistance against attempts by the U.S., the European Union and other wealthy nations to make emerging economies pitch in to reduce global greenhouse gas emissions and help the poorest countries cope with climate change.
Nijar said it was unreasonable to expect countries like Malaysia to rapidly shift from fossil fuels — the biggest source of man-made greenhouse gas emissions — to cleaner sources of energy.
"We cannot just switch overnight ... and go to renewables," he said, on a coffee break between meetings.
This accord is the first time all countries are expected to pitch in — the previous emissions treaty, the 1997 Kyoto Protocol, only included rich countries.
