As the final gavel came down at 5.30am on Sunday morning, the COP29 UN climate change conference in Baku closed with many unsettled grievances and some ruffled feathers.
From the controversial new climate finance goal, to the adoption of rules for a global carbon market and stalled efforts on cutting planet-heating emissions, the summit’s outcomes were contested and widely seen as inadequate to tackle the urgency of the climate crisis.
The finance deal was hailed as “the start of a new era on climate finance” by the EU’s climate commissioner, but condemned as a “joke” by Nigeria – and India rejected it fiercely as being “too little, too late”.
Climate Home News unpacks COP29’s successes and failures, most of which require further work next year on the path to COP30 in Brazil.
New climate finance goal
Tagged the “Finance COP”, all eyes in Baku were on negotiations towards a new collective quantified goal (NCQG) for climate finance to kick in from 2026. The final deal for wealthy governments to channel at least $300 billion a year by 2035 to developing countries replaced the previous $100-billion annual target set in 2009 for the 2020-2025 period.
From the very beginning, developed countries were strategically silent, as they avoided revealing the amount of finance – or “quantum” – they would be prepared to offer for the new target. Developing-country asks ranged from $440 billion, $600 billion and $900 billion of government finance per year. They proposed an overall target of $1.3 trillion which would include private finance mobilised by governments, but not market-rate loans, export credits or private investment in general.
As negotiations moved into the second week and towards the final days, developing countries became impatient with the lack of clarity. As whispers of a number ranging from $200bn-$300bn spread through the conference, Bolivian negotiator Diego Pacheco labelled the $200bn figure “a joke” during a press conference in the sidelines of COP29.
Reaching an agreement at #COP29 was essential to keep the 1.5°C global warming limit alive.
I had hoped for a more ambitious outcome – on both finance & mitigation – to meet the scale of the great challenge we face, but the agreement reached provides a base on which to build.…

On Friday, the last official day of the conference, a number was finally put on the table by the COP29 presidency, suggesting $250bn a year – to the disappointment of developing countries. The African Group’s lead negotiator Ali Mohamed said this was “totally unacceptable”.
The talks took a further dramatic turn on Saturday when governments received a draft text containing a slightly higher offer of $300bn a year for the core government-led finance goal. This and other issues infuriated the Least Developed Countries (LDCs) and Small Island Developing States (SIDS), who stormed out of the negotiations in protest just hours before the closing plenary.

After LDCs and SIDs won some concessions – but not on the size of the goal – the presidency gavelled through the deal pledging at least $300 billion a year by 2035, with developed countries “taking the lead” on providing it. The text says the money will come “from a wide variety of sources, public and private, bilateral and multilateral, including alternative sources”.
The existing $100bn goal includes direct government finance, a proportion of the public funding that flows through multilateral development banks (MDBs) and private finance “mobilised” by government money and export credits. It is unclear if the $300bn covers the same elements or more, experts said.
Under the $100bn goal, only 70% of MDB climate finance is counted, which excludes the share contributed by large emerging economies like China, India and Brazil.
But to the anger of some developing countries – especially India – the new goal recognises “the voluntary intention” of governments “to count all climate-related outflows from and climate-related finance mobilized by multilateral development banks towards achievement of the goal”.

SIDS finance negotiator Michai Robertson told Climate Home that how MDB finance is counted and which private sources would be included in the $300bn will only be decided by the UNFCCC’s Standing Committe on Finance when countries report the first post-2025 figures, which will not be until 2028.

A larger target of $1.3 trillion a year by 2035 was also set in Baku to scale up all sources of spending to combat climate change, including private investments in the Global South that are not linked to governments. How this broader target will be reached is uncertain, and will be discussed in the coming year under a “Baku to Belem Roadmap to 1.3T”.
The roadmap will look into “grants, concessional and non debt-creating instruments, and measures to create fiscal space” and produce a report by COP30 next year in Belem. It was first announced at a press conference in Baku by ministers from Colombia, Kenya, Barbados, Honduras and Panama. Barbados’ minister said it would consider measures such as redirecting fossil fuel subsidies in rich countries to climate action in the Global South.
SIDS negotiator Robertson criticised the roadmap as “a lot of smoke and mirrors”, adding that it was unclear how it would work.
Meanwhile the new finance goal also “encourages” developing countries to make contributions to climate finance “on a voluntary basis”, which they were not requested to do for the existing $100bn goal. While no countries are specified, the rich donor governments that pushed for this have said they want wealthier developing countries like China, Saudi Arabia and other Gulf states to chip in.
Cutting greenhouse gas emissions
Last year at COP28 in the UAE, countries completed the first global review of climate policies under the 2015 Paris Agreement – a process known as the global stocktake (GST). Among other things, last year’s deal saw countries commit to triple renewable energy capacity by 2030 and “transition away” from fossil fuels in energy systems in a fair manner to achieve the goals of the Paris pact, including limiting global warming to “well below” 2C and ideally to 1.5C.
In Baku, countries were meant to launch the “UAE Dialogue” to work out how to implement the recommendations from the GST and inform the upcoming round of new and stronger national climate plans – known as nationally determined contributions (NDCs) – due in 2025.
However, at COP29 countries did not reach consensus on advancing the UAE Dialogue, after Saudi Arabia blocked any references to fossil fuels in the text, in what observers described as “destructive” opposition.
Governments were also split on whether the UAE Dialogue should address issues beyond financing the commitments made at COP28, which Saudi negotiators claimed was the main scope of the dialogue. They used this as an excuse to avoid discussions on the energy transition.

A watered-down draft text proposed to “reaffirm” last year’s pledge without calling out fossil fuels by name, and also emphasised the role of “transitional fuels” – which could be interpreted to mean fossil gas.
Latin American countries, developed countries and small islands opposed this text, meaning that the talks on the dialogue had to be pushed to June 2025, aiming for a new outcome at COP30 next November.
Without a deal in Baku, countries missed the chance to adopt two new targets viewed as key for the energy transition: one aiming to increase energy storage capacity to 1,500 gigawatts by 2030 and another pledging to add 25 million kilometres of power grids by 2030.
In a different strand of the talks – a “non-prescriptive” effort to enhance emissions reductions known as the Mitigation Work Programme (MWP) – countries approved a weak text after Saudi negotiators almost managed to collapse talks on it earlier in the summit, causing the COP29 presidency to step in and revive them.
All mentions of fossil fuels were removed from the MWP, as well as any mention of COP28’s pledges to reverse deforestation by 2030, phase out fossil fuel subsidies and triple renewables by 2030.
The outcome frustrated developed countries which said the text failed to send strong signals for ambitious NDCs next year. Germany’s climate envoy Jennifer Morgan called the MWP decision a “big step back”.
Just transition
Countries also failed to reach an agreement on the just transition work programme (JTWP) at COP29 – a deal meant to support workers and communities affected by the transition away from fossil fuels towards cleaner energy.
Governments were divided on issues of human and labour rights, measures seen as restricting free trade, adaptation and emissions reductions. A major bone of contention was whether to designate finance to support plans for a just transition.
Fatuma Hussein, Africa’s lead negotiator on just transition, told Climate Home that developed countries wanted to keep discussions focused on “national dimensions” rather than what needs to be done internationally to enable just transition on a global scale. She added that the lack of finance was “the biggest departure point” causing developing countries to reject the draft text.
Negotiations on this issue fell down the COP29 presidency’s list of priorities as the finance talks became heated. It set up a last-minute contact group and presented a final draft to save the JTWP, but no agreement was reached. Talks will continue in June next year, with international trade unions expressing their concern over the lack of a decision on next steps in Baku.

Global goal on adaptation
Work on the global goal on adaptation (GGA) – which is enshrined in the Paris Agreement but has yet to be implemented – made little progress during most of COP29, due to a lack of consensus on the means of implementation, generally understood to mean finance. In the end, a procedure to move the goal forward was agreed, called the Baku Adaptation Road Map.
Unwillingness from developed countries to put money on the table, as well as the difficulty of selecting indicators to measure progress, held back the talks at COP29, experts told Climate Home.
The GGA was adopted in 2015 with a view to enhancing resilience to climate change impacts, but countries defined a set of guidelines for it only last year, known as the UAE Framework. In Baku, countries were meant to advance on identifying indicators to measure progress, under a process known as the UAE-Belém Work Programme, which is due to be finalised next year at COP30.
However, in addition to the contention around finance, the role of transformational adaptation – meaning deep, long-term societal changes that influence sustainable development – was another obstacle to progress, as some developing countries like Senegal kicked back against it, saying it could throw up new barriers in accessing finance.
In the second week of COP29, countries agreed to defer a review of the GGA framework until after the second global stocktake in 2028. But the Baku Adaptation Road Map was launched to enable talks to continue in 2025.
Richard Klein, a senior researcher on adaptation at the Stockholm Environment Institute, told Climate Home that the GGA did not take substantive steps forward at COP29, further delaying implementation. Meanwhile, he said, “the gap between the adaptation action needed and what is being implemented continues to widen.”

Gender work programme
This year, the main focus of the gender negotiations at the UN climate summit was the renewal of the Lima Work Programme (LWP), under which a Gender Action Plan is produced every five years – both of which establish guidelines for gender-responsive climate policies.
Some conservative countries, including the Vatican, Saudi Arabia and Egypt, successfully lobbied to remove some human rights-related language from the decision text on issues including diversity and intersectionality that had been being championed mainly by Latin American nations and the EU.
In the end, an agreement was reached, renewing the Lima Work Programme for another 10 years, with a review scheduled in five years, and a new gender action plan due to be drawn up in 2025.
Another topic of discussion was whether to house the LWP under the Paris Agreement or the UN climate convention. Some parties wanted it to be addressed in talks on both, but others argued that that would double the work. Countries decided to keep it just under the convention.
They also agreed to work on data that will be broken down by gender and age, gender-responsive implementation of just transitions, creating quality jobs for women that are aligned with national climate plans, and simplifying access to finance for grassroots women’s groups and Indigenous women.

Carbon markets
At COP29, talks on setting up a new global carbon market made a significant breakthrough after nearly a decade of discussions, as countries agreed on a package of rules under the Paris Agreement’s “Article 6”.
On the first day of the Baku summit, the COP29 presidency scored an early win as countries approved guidelines laying the foundations for a regime to develop and trade carbon credits. This agreement was hailed by COP29 President Mukhtar Babayev as a “breakthrough” that “achieves full operationalisation of Article 6” – but experts criticised the procedure that was followed.
After failing to secure agreement in previous years, the rules were eventually crafted by a technical committee and then presented to governments at COP29.
With approval of the rules on Article 6.2, which regulates bilateral emissions trading between countries, and 6.4, which sets up an international carbon market, countries will now finalise technical details and could kick off the new markets from 2025.
But campaigners expressed concerns over the quality of the credits and how to deal with any problems. According to Carbon Market Watch, the rules agreed for Article 6.2 may not be strong enough to ensure real emissions reductions, as trades require less immediate transparency. Key technical information is not required to be disclosed until after trades have already happened, which could take years, the NGO warned.
The first batch of credits to be traded under the new Paris market is likely to consist of old offsets originally developed under the Kyoto Protocol-era’s Clean Development Mechanism (CDM), many of which were regarded as delivering little concrete benefit for the climate.

Efforts to green lithium extraction face scrutiny over water use
Mining companies are showcasing new technologies which they say could extract more lithium – a key ingredient for electric vehicle (EV) batteries – from South America’s vast, dry salt flats with lower environmental impacts.
But environmentalists question whether the expensive technology is ready to be rolled out at scale, while scientists warn it could worsen the depletion of scarce freshwater resources in the region and say more research is needed.
The “lithium triangle” – an area spanning Argentina, Bolivia and Chile – holds more than half of the world’s known lithium reserves. Here, lithium is found in salty brine beneath the region’s salt flats, which are among some of the driest places on Earth.
Lithium mining in the region has soared, driven by booming demand to manufacture batteries for EVs and large-scale energy storage.
Mining companies drill into the flats and pump the mineral-rich brine to the surface, where it is left under the sun in giant evaporation pools for 18 months until the lithium is concentrated enough to be extracted.
The technique is relatively cheap but requires vast amounts of land and water. More than 90% of the brine’s original water content is lost to evaporation and freshwater is needed at different stages of the process.
One study suggested that the Atacama Salt Flat in Chile is sinking by up to 2 centimetres a year because lithium-rich brine is being pumped at a faster rate than aquifers are being recharged.
Lithium extraction in the region has led to repeated conflicts with local communities, who fear the impact of the industry on local water supplies and the region’s fragile ecosystem.
The lithium industry’s answer is direct lithium extraction (DLE), a group of technologies that selectively extracts the silvery metal from brine without the need for vast open-air evaporation ponds. DLE, it argues, can reduce both land and water use.
Direct lithium extraction investment is growing
The technology is gaining considerable attention from mining companies, investors and governments as a way to reduce the industry’s environmental impacts while recovering more lithium from brine.
DLE investment is expected to grow at twice the pace of the lithium market at large, according to research firm IDTechX.
There are around a dozen DLE projects at different stages of development across South America. The Chilean government has made it a central pillar of its latest National Lithium Strategy, mandating its use in new mining projects.
Last year, French company Eramet opened Centenario Ratones in northern Argentina, the first plant in the world to attempt to extract lithium solely using DLE.
Eramet’s lithium extraction plant is widely seen as a major test of the technology. “Everyone is on the edge of their seats to see how this progresses,” said Federico Gay, a lithium analyst at Benchmark Mineral Intelligence. “If they prove to be successful, I’m sure more capital will venture into the DLE space,” he said.
More than 70 different technologies are classified as DLE. Brine is still extracted from the salt flats but is separated from the lithium using chemical compounds or sieve-like membranes before being reinjected underground.
DLE techniques have been used commercially since 1996, but only as part of a hybrid model still involving evaporation pools. Of the four plants in production making partial use of DLE, one is in Argentina and three are in China.
Reduced environmental footprint
New-generation DLE technologies have been hailed as “potentially game-changing” for addressing some of the issues of traditional brine extraction.
“DLE could potentially have a transformative impact on lithium production,” the International Lithium Association found in a recent report on the technology.
Firstly, there is no need for evaporation pools – some of which cover an area equivalent to the size of 3,000 football pitches.
“The land impact is minimal, compared to evaporation where it’s huge,” said Gay.


The process is also significantly quicker and increases lithium recovery. Roughly half of the lithium is lost during evaporation, whereas DLE can recover more than 90% of the metal in the brine.
In addition, the brine can be reinjected into the salt flats, although this is a complicated process that needs to be carefully handled to avoid damaging their hydrological balance.
However, Gay said the commissioning of a DLE plant is currently several times more expensive than a traditional lithium brine extraction plant.
“In theory it works, but in practice we only have a few examples,” Gay said. “Most of these companies are promising to break the cost curve and ramp up indefinitely. I think in the next two years it’s time to actually fulfill some of those promises.”
Freshwater concerns
However, concerns over the use of freshwater persist.
Although DLE doesn’t require the evaporation of brine water, it often needs more freshwater to clean or cool equipment.
A 2023 study published in the journal Nature reviewed 57 articles on DLE that analysed freshwater consumption. A quarter of the articles reported significantly higher use of freshwater than conventional lithium brine mining – more than 10 times higher in some cases.
“These volumes of freshwater are not available in the vicinity of [salt flats] and would even pose problems around less-arid geothermal resources,” the study found.
The company tracking energy transition minerals back to the mines
Dan Corkran, a hydrologist at the University of Massachusetts, recently published research showing that the pumping of freshwater from the salt flats had a much higher impact on local wetland ecosystems than the pumping of salty brine. “The two cannot be considered equivalent in a water footprint calculation,” he said, explaining that doing so would “obscure the true impact” of lithium extraction.
Newer DLE processes are “claiming to require little-to-no freshwater”, he added, but the impact of these technologies is yet to be thoroughly analysed.
Dried-up rivers
Last week, Indigenous communities from across South America held a summit to discuss their concerns over ongoing lithium extraction.
The meeting, organised by the Andean Wetlands Alliance, coincided with the 14th International Lithium Seminar, which brought together industry players and politicians from Argentina and beyond.
Indigenous representatives visited the nearby Hombre Muerto Salt Flat, which has borne the brunt of nearly three decades of lithium extraction. Today, a lithium plant there uses a hybrid approach including DLE and evaporation pools.
Local people say the river “dried up” in the years after the mine opened. Corkran’s study linked a 90% reduction in wetland vegetation to the lithium’s plant freshwater extraction.
Pia Marchegiani, of Argentine environmental NGO FARN, said that while DLE is being promoted by companies as a “better” technique for extraction, freshwater use remained unclear. “There are many open questions,” she said.

Stronger regulations
Analysts speaking to Climate Home News have also questioned the commercial readiness of the technology.
Eramet was forced to downgrade its production projections at its DLE plant earlier this year, blaming the late commissioning of a crucial component.
Climate Home News asked Eramet for the water footprint of its DLE plant and whether its calculations excluded brine, but it did not respond.
For Eduardo Gigante, an Argentina-based lithium consultant, DLE is a “very promising technology”. But beyond the hype, it is not yet ready for large-scale deployment, he said.
Strong regulations are needed to ensure that the environmental impact of the lithium rush is taken seriously, Gigante added.
In Argentina alone, there are currently 38 proposals for new lithium mines. At least two-thirds are expected to use DLE. “If you extract a lot of water without control, this is a problem,” said Gigante. “You need strong regulations, a strong government in order to control this.”

Maryland’s Conowingo Dam Settlement Reasserts State’s Clean Water Act Authority but Revives Dredging Debate
The new agreement commits $340 million in environmental investments tied to the Conowingo Dam’s long-term operation, setting an example of successful citizen advocacy.
Maryland this month finalized a $340 million deal with Constellation Energy to relicense the Conowingo Dam in Cecil County, ending years of litigation and regulatory uncertainty. The agreement restores the state’s authority to enforce water quality standards under the Clean Water Act and sets a possible precedent for dozens of hydroelectric relicensing cases nationwide expected in coming years.
