The deal also lays the groundwork for next year’s climate summit, to be held in the Amazon rainforest of Brazil, where countries are meant to map out the next decade of climate action.

The summit cut to the heart of the debate over financial responsibility of industrialised countries - whose historic use of fossil fuels has caused the bulk of greenhouse gas emissions - to compensate others for worsening damage from climate change.

It also laid bare divisions between wealthy governments constrained by tight domestic budgets and developing nations reeling from costs of storms, floods and droughts.

Negotiations had been due to finish on Friday, but ran into overtime as representatives from nearly 200 countries struggled to reach consensus. Talks were interrupted Saturday as some developing countries and island nations walked away in frustration.

“We are leaving with a small portion of the funding climate-vulnerable countries urgently need. It isn’t nearly enough, but it’s a start,” said Tina Stege, Marshall Islands climate envoy.

Nations have been seeking financing to deliver on the Paris Agreement goal of limiting global temperature rise to 1.5 degrees above pre-industrial levels - beyond which catastrophic climate impacts could occur.

The world is currently on track for as much as 3.1C of warming by the end of this century, according to the 2024 UN Emissions Gap report, with global greenhouse gas emissions and fossil fuels use continuing to rise.

Sunday’s deal failed to set out detailed steps for how countries will act on last year’s UN climate summit pledge to transition away from fossil fuels and triple renewable energy capacity this decade. Some negotiators said Saudi Arabia had attempted to block such a plan during the talks.

A Saudi official did not immediately provide comment.

What counts as a developed nation?

The roster of countries required to contribute - about two dozen industrialised countries, including the US, European nations and Canada - dates back to a list decided during UN climate talks in 1992.

European governments have demanded others join them in paying in, including China, the world’s second-biggest economy, and oil-rich Gulf states. The deal encourages developing countries to make contributions, but does not require them.

The agreement also includes a broader goal of raising $2 trillion in climate finance annually by 2035 - which would include funding from all public and private sources and which economists say matches the sum needed to address global warming.

Securing the deal was a challenge from the start.

Donald Trump’s US presidential election victory this month has raised doubts among some negotiators that the world’s largest economy would pay into any climate finance goal agreed in Baku. Trump has called climate change a hoax and promised to again remove the US from international climate cooperation.

Western governments have seen global warming slip down the list of national priorities amid surging geopolitical tensions, including Russia’s war in Ukraine, conflict in the Middle East, and rising inflation.
