Main points of the $300 billion climate deal

Here are the main points of the agreement reached at COP29 in Baku:

- $300 billion -

Under a framework established by the UN in 1992, 23 developed countries -- and the European Union -- historically responsible for most planet-heating emissions are obliged to contribute to climate finance.

The Baku accord raises the amount of money that developed countries must provide to at least $300 billion per year by 2035.

It is higher than the $100 billion that is currently required under a previous agreement that runs until next year.

But it falls well short of the $500 billion that some developing countries had demanded at the fraught negotiations in Baku.

The deal states that the money will come directly from a "wide variety of sources" including government budgets, private sector investment, and other financing.

It also cites "alternative sources" -- a reference to potential global taxes under discussion on the aviation and maritime industries, and the rich.

The hope is that the money from developed countries will help boost private investment to reach an ambitious goal -- written into the deal -- of delivering at least $1.3 trillion per year by the next decade.

That is the amount that experts commissioned by the United Nations said was needed by 2035.

"With these funds and with this structure, we are confident we will reach the 1.3 trillion objective," EU climate commissioner Wopke Hoekstra told fellow COP29 delegates.

- China role -

The United States and EU had pushed to broaden the donor base to include countries that are still listed as developing but have now become wealthy, such as China and Saudi Arabia.

But China, the world's second-biggest economy and top emitter of greenhouse gases, has steadfastly refused to change its status while recalling that it already provides bilateral aid.

The deal states that developed nations would be "taking the lead" in providing the $300 billion -- implying that others could join.

The text "encourages" developing countries to "make contributions" that would remain "voluntary".

There was one novelty: the climate finance that developing countries such as China provide via multilateral development banks will count towards the $300 billion goal.

"It is also a matter of fairness and of importance to us that all those with the ability to do so should contribute," Hoekstra said.

"Therefore it is good, given the size of the problem, that we enlarge the contributor base on a voluntary basis."

- Share of money -

The negotiations were also the scene of disagreements within the developing world.

The Least Developed Countries bloc had asked that it receive $220 billion per year, while the Alliance of Small Island States wanted $39 billion -- demands that were opposed by other developing nations.

The figures did not appear in the final deal.

Instead, it calls for tripling other public funds they receive by 2030.

The next COP, in Brazil in 2025, is expected to issue a report on how to boost climate finance for these countries.

- Fossil fallout -

Activists are worried that the promise to "transition away" from fossil fuels -- the main achievement of COP28 in Dubai -- disappeared from the final deal in Baku.

A text that was supposed to reinforce implementation of the landmark agreement was ultimately not adopted at the close of COP29, after a long battle that had already largely emptied it of its substance.

All that remained in the final documents was an implicit reference to the existence of the deal adopted last year.

This reflected a "devil's bargain" with producer countries, according to one European negotiator.

One of the European Union's priorities, opposed by Saudi Arabia, was to agree to annual monitoring of efforts to move away from oil, gas and coal. That did not reach the final agreement.
