Over two weeks in November, more than 55,000 government negotiators, business representatives, activists and journalists gathered in Azerbaijan’s capital Baku for the annual conference of parties (COP) to the UN’s climate change convention (UNFCCC).

They were joined on the opening days of COP29 by about 105 heads of state and government who made back-to-back speeches. Most, like UNFCCC Executive Secretary Simon Stiell, emphasised the urgency of addressing the climate crisis. But the host, Azerbaijan’s President Ilham Aliyev, went the other way with a speech praising fossil fuels as a “gift of the god” and calling on leaders to be “realistic”.

Negotiators and ministers then got to work hammering out a new goal to finance climate action in developing countries after the current one runs out next year. Those talks inched forward for two weeks, with rich nations refusing to put a concrete offer on the table.

At the last minute, as the pavilions of the international trade show that accompanies COPs were packed away on the official closing day, the negotiations exploded. On that Friday, a number for the core finance goal was finally put on the table, sparking anger among developing nations which dismissed it as too low. On Saturday evening, negotiators from small islands and the world’s poorest countries stormed out – and a target of $300bn a year by 2035 was pushed through in controversial circumstances in the early hours of Sunday.

Climate Home had a reporting team in Baku throughout, producing a bulletin and newsletter each day. As well as our explainer on what was agreed at COP29, below we bring you our five most dramatic moments from the Baku talks.

1.UN’s climate head gets personal

At the start of every COP, the head of the UN’s climate body gives what amounts to a motivational speech, calling on governments to do more to tackle the climate crisis.

This year, instead of reeling off statistics or listing climate-driven disasters, Simon Stiell got personal. He became emotional as he put up on a big screen a photograph of him hugging his neighbour Florence in front of her hurricane-destroyed house on their native Caribbean island of Carriacou (part of Grenada).

“At 85, Florence has become one of the millions of victims of climate change this year alone,” he said. In perhaps a coded reference to Donald Trump’s recent election as US president, he said Florence was “knocked down and getting back up again” – and government officials in the audience should too.

2. Host-nation leader calls fossil fuels “gift of the god”

On COP29’s second day, after a long cultural ceremony of music and dancing, Azerbaijan’s President Ilham Aliyev kicked off a series of speeches by the UN secretary-general and world leaders – and used it to double down on his past public backing of fossil fuels.

After attacking American”fake news media” and “so-called independent NGOs”, Aliyev repeated his claim that fossil fuels are “a gift of the god” and called out the European Union for criticising fossil fuels while doing a multi-year deal to buy gas from Azerbaijan.

He later used a summit of small island developing states to accuse France and the Netherlands of ongoing “colonial rule”, sparking a diplomatic spat with those countries and the European Union, which sprang to their defence. As a result, France’s environment minister decided to boycott COP29.

3. Finance goal: “Is it a joke?”

Nine days into COP29, developed countries had yet to put forward a proposal for how much they were willing to contribute to the post-2025 climate finance goal.

The most anyone had to go on was a Politico report that the European Union was considering $200bn-300bn a year – so the $200bn figure was raised by a journalist at a press conference of Bolivia’s chief negotiator Diego Pacheco, Uganda’s Adonia Ayebare and Kenya’s Ali Mohamed.

“Is it a joke?” asked Pacheco with a smile, to applause from climate campaigners in the room.

Ayebare laughed and repeated his words, before Mohamed added more sternly: “We don’t know where you’re getting the 200 but, joke or otherwise, the quantum we are putting forward is nothing near to what you have just suggested.”

This off-the-cuff remark led to the word “joke” being used repeatedly by campaigners and negotiators about the finance goal for the rest of the summit. The next day, the COP29 presidency published a $250-billion-a-year proposal, which increased to $300 billion in the final agreement.

4. Vulnerable nations storm out

On the last night of the negotiations, all government delegations were summoned to a meeting room where Azeri diplomats showed them a copy of the latest draft text.

According to Michai Robertson, finance negotiator for the Alliance of Small Island States (AOSIS), developed countries and big developing nations like China, India and Brazil had been consulted by the presidency the night before, with those conversations informing the new text.

But, he said, AOSIS and the Least Developed Countries (LDCs) had not been asked for their views. So after reading it, the chair of the LDC group Evans Njewa told the room: “We are not ready to associate with this paper and our sitting here means nothing to us.”

“If you want to continue discussing on this paper, then you can do so – this will allow us to leave this room – when you are done, maybe you call us back,” he added.

He called for the meeting’s suspension, stood up, picked up his bag and walked out. So did the rest of the negotiators for his group and those of AOSIS.

Robertson was among them. He told Climate Home the walk-out was unplanned and spontaneous.

Robertson said the presidency then gathered representatives of the LDCs, small island developing states (SIDS) and developed countries upstairs, where the LDCs and SIDs won compromises like a commitment to triple the amount of finance that goes through multilateral UN climate funds like the Green Climate Fund.

On their way to that meeting, rich-country negotiators were mobbed by climate campaigners and journalists who had gathered in the hall outside the meeting rooms. Germany’s climate envoy Jennifer Morgan rushed out, leaving journalists running after her as she refused to answer questions on her way to the presidency’s private office.

US climate envoy John Podesta, meanwhile, walked off more slowly and was surrounded by security and TV cameras as a campaigner shouted “shame” and “you’re selling us out”. He told reporters that he hoped this was the “storm before the calm”.
