The outcome of Brazil’s COP30 climate summit remained uncertain after the European Union refused to accept a draft deal it said would not advance efforts to curb greenhouse gas emissions.

The two-week conference in Belem was meant to end Friday evening, but continued late into the night.

Brazil urged nations to bridge divides on issues including fossil fuels. “We must reach an agreement,” COP30 President André Corrêa do Lago said.

Some emerging economies pushed back, demanding that the EU provide more climate finance.

“If there is a pathway for fossil fuel, there has to be a pathway for climate finance as well,” said a developing-country negotiator.

A draft text released Friday contained no reference to fossil fuels after options were removed due to opposition from many countries.

Earlier, around 80 governments had demanded a plan to shift away from fossil fuels, but many later indicated they would accept the deal without it.

“Under no circumstances are we going to accept this,” EU Commissioner Wopke Hoekstra said.

The EU said it could move on finance only if the emissions-cutting language was strengthened. Some European negotiators said the bloc was considering walking away.

A Brazilian negotiator said fossil fuel language was unlikely to return.

Options included a voluntary side deal on fossil fuels.

Three sources said the Arab Group warned that targeting its energy industries would collapse negotiations.

The draft deal also called for tripling global climate adaptation finance by 2030, but did not specify the source.

A final agreement requires consensus among nearly 200 countries. Corrêa do Lago said unity was vital, especially with the US absent, and added: “The world is watching.”
