Portugal Colonial - Public money 'must be at core' of new climate pact: UN's Stiell

The developing world needs trillions of dollars to help fund clean energy and prepare for climate change, but the world cannot agree how to raise the money.

It is hoped nations can resolve this at next month's UN COP29 climate summit despite rifts over how much is needed, what is covered, who pays for it, and how.

Wealthy nations most responsible for global warming to date, like the United States and European Union, are obligated to pay and face pressure to raise their existing commitment of $100 billion a year.

But they say they cannot foot the bill alone, and want others to help meet whatever 'climate finance' goal is inked when nearly 200 nations gather for COP29 in Azerbaijan.

"It's not my job to prejudge what the new goal will look like," said Simon Stiell, executive secretary of the UN Framework Convention on Climate Change (UNFCCC), which convenes the COP negotiations but does not influence its decisions.

"But it's clear public finance must be at the core. As much of this finance as possible needs to be grant or concessional, and must be made more accessible to those who need it most."

Developing countries -- most of the world in UNFCCC terms, from powerful emerging markets like China to low-lying island states -- say historic polluters are morally obligated to dig deep into their pockets.

They are also legally bound under the Paris climate agreement of 2015 to take the lead in providing and mobilising such money.

But some donors are under financial and political constraint, and have baulked at demands they commit huge sums of new money from their budgets.

They want private investment to play a much bigger role and for China, the oil-rich Gulf states, and other wealthy emerging markets to also help fill the pot.

Stiell said who pays and how much could be ironed out at COP29 "but we are not -- we are not -- going there to renegotiate the Paris Agreement".

Azerbaijan on Monday said developing countries needed trillions of dollars in climate finance but a goal of hundreds of billions in public money would be more "realistic".

The hosts expect more than 100 heads of state and government to attend the two-week summit in its capital Baku, which gets underway on November 11.
