The outcome of Brazil’s COP30 climate summit was left hanging in the balance, with the European Union refusing to accept a draft deal it said would fail to advance global efforts to curb greenhouse gas emissions driving climate change.

The two-week conference being held in the Amazon city of Belem had been scheduled to end Friday evening, but blew past that deadline as negotiations continued late into the night.

Brazil has cast the summit as a make-or-break moment for global climate cooperation, urging nations to bridge divides on issues including the future of fossil fuels and to send a message that concerted global action is the best way forward.

“This cannot be an agenda that divides us,” COP30 President André Corrêa do Lago told delegates in a public plenary session before releasing them for further negotiations.

“We must reach an agreement between us.”

Some emerging economies hit back at the EU’s position, demanding the bloc commit more finance to help poorer nations cope with climate change.

“We can’t just work with one pathway. If there is a pathway for fossil fuel, there has to be a pathway for climate finance as well,” said a negotiator for a developing country, who was granted anonymity to discuss the closed-door negotiations.

The rifts over fossil fuels, cutting CO2 emissions faster and finance highlighted the difficulty of reaching a consensus at the annual conference, a perennial test of global resolve to avert the worst impacts of global warming.

A draft text for a deal, released by Brazil before dawn on Friday, contained no reference to fossil fuels, dropping a range of options on the subject that had been included in an earlier version.

Scores of countries, including major oil and gas producer nations, had opposed the options.

Earlier in the summit, some 80 governments had demanded COP30 deliver a plan to shift away from fossil fuels. But by Friday night, many of those nations had indicated in closed-door talks they would accept the deal without it, negotiators said.

Burning fossil fuels emits greenhouse gases that are by far the largest contributors to global warming.
