This year marks a decade since nations successfully negotiated the Paris Agreement, a landmark treaty that has been the guiding force for international climate politics ever since.
Yet, with another round of negotiations looming at COP30 in November, there has been growing discontent with the UN climate process.
Critics say the talks are not doing enough to accelerate emissions cuts, tackle fossil fuels or raise climate funds for developing countries, among other concerns.
Influential figures in climate politics and civil society groups say COPs are in need of an “urgent overhaul” and have launched various manifestos for change.
This has been recognised by the Brazilian COP30 presidency, which has acknowledged the “growing calls for change” and asked parties to “reflect on the future of the process itself”.
All of this comes amid concerns about a “crisis” of multilateralism, widespread conflict and escalating climate hazards.
Carbon Brief asked 16 leading experts about how they think the UN climate talks could be reformed, including Christiana Figueres, Todd Stern, Prof Navroz K Dubash, Bernice Lee, Paul Watkinson, Dr Joanna Depledge, Dr Jennifer Allan, Sandrine Dixson-Declève and Li Shuo.
The contributors’ answers are presented via the thematic sections below.
- Has the Paris Agreement been a success?
- How could the negotiations themselves be improved?
- Can UN climate talks drive faster emissions cuts?
- How could COPs ensure broader accountability?
- Do UN climate talks need majority voting?
- What should the role of the COP presidency be?
- Do fossil-fuel companies have too much influence?
- Are COPs too big?
- How could COP participation be improved?
- How can COPs drive change outside the UN process?
Has the Paris Agreement been a success?
Todd Stern, former US special envoy for climate change: Paris has performed well in some respects, including strengthening both its temperature and emission goals in light of evolving science. It also led to a first global stocktake that called for tripling renewable energy and doubling energy efficiency by 2030 – and transitioning away from fossil fuels – in order to achieve net-zero emissions by 2050.
Bernice Lee, distinguished fellow and senior advisor at Chatham House: It can be hard to remember that the process remains one of the most successful multilateral endeavours in recent history. It has delivered what few thought possible: agreement among nearly 200 countries on a global issue that cuts to the core of national sovereignty, economic models and domestic politics. That the COP process delivered the Paris Agreement – and more recently, an agreement to transition away from fossil fuels – is no small feat. It is also easy to forget that, prior to Paris, the world was on track for a catastrophic 4-5C of warming. Today’s pledges, while still inadequate, have bent that curve closer to 2.5-3C – still unsafe, but a meaningful shift…Rather than dwelling on the system’s imperfections, the question is whether it can evolve, realistically and politically. Dismantling the current system is unlikely to yield a stronger or more equitable one with the authority to override national decisions. The current process, after all, emerged from the ruins of earlier failures.
Kaveh Guilanpour, vice president for international strategies at the Centre for Climate and Energy Solutions: In the aftermath of every COP, there are calls to reform the UNFCCC. But we should be aiming for an evolution, not a revolution, for three reasons. Firstly, a revolution would almost certainly not result in something stronger than we already have. It is hard to imagine that it would be possible to adopt the Paris Agreement in the current geopolitical and economic context. Secondly, the Paris Agreement is working, albeit not fast enough. Thirdly, and most importantly, the biggest barriers to the effective functioning of the UNFCCC and delivering on the Paris Agreement are deficiencies in the underlying politics. No amount of tweaking of the UNFCCC process can make up for that.
How could the negotiations themselves be improved?
Dr Monserrat Madariaga Gomez de Cuenca, environmental lawyer at Legal Response International: It is time to fully acknowledge that there is a crisis of trust in the UN climate process and take appropriate measures to limit it. Parties mistrust each other and stakeholders mistrust the limited results emerging from 30 years of climate talks.
Paul Watkinson, former EU climate negotiator: Whilst the negotiating process can be frustrating, it remains essential. I would focus on making the workload more manageable, for example by grouping items on agendas and organising work on a multiannual basis. The aim should be to give enough time to every item – rather than addressing everything together each time – and develop the understanding that not every item needs a negotiated outcome at each meeting.
Kaveh Guilanpour: [We should] embrace the role of multilateral negotiations at the core – and recognise that this is what attracts world leaders and non-parties to COPs – but work towards contextualising the negotiations in a wider ecosystem of climate action, to which they are clearly linked. Do not place all expectations only on the negotiated outcomes.
Christiana Figueres, former executive secretary of the UNFCCC: We could…streamline repetitive and overloaded agendas – and elevate the accountability of COP presidents through a public oath of office, potentially administered by the UNFCCC bureau, that reminds the COP presidency of its role.
Dr Joanna Depledge, research fellow at the University of Cambridge and former UNFCCC secretariat staff member: Overall, the negotiations have proved resistant to anything but very limited reform. Why so? The fact is that many of the perceived inefficiencies are not flaws as such, but inherent to a global process where all nations are sovereign and equal – and all want a say. They are also inherent to the very issue of climate change, which, because it is so multifaceted…inevitably spawns an ever-expanding agenda, while attracting ever more government and civil society participants. And process is politics: moves to restructure the negotiations inevitably come up against powerful forces who know how to maximise their influence in the existing system and far prefer the status quo.
Dr Monserrat Madariaga Gomez de Cuenca: [COPs should] avoid rushed, closed-door negotiations without party consultations, which make implementation impossible. When draft text appears in the eleventh hour and is forwarded to the closing plenary without proper discussion, the possibilities of parties gaslighting each other on the actual “meaning” and “intention” of the text multiply. Language such as “transitioning away from fossil fuels” or the path towards the “Baku to Belém Roadmap to $1.3tn” – where the wording is not clear – allows parties to cherry-pick the most favourable interpretation, undermining the implementation of decisions that were already difficult to achieve.
Dr Joanna Depledge: Streamlining agendas and limiting government delegation size are worth fighting for, but imposing criteria for selecting COP hosts and excluding private companies involved in high-carbon activities are non-starters. If the real problem is that the COP is not taking decisions in line with the science, then the answer is not tinkering around the edges of procedure and process. What is needed is a major strategic rethink and more fundamental reforms – notably to decision-making practices and voting – as I argue elsewhere.
Harjeet Singh, founding director at the Satat Sampada Climate Foundation: The process must change: streamline negotiations, review consensus rules and ban fossil-fuel lobbyists from influencing texts. Centre the voices of Indigenous peoples, frontline communities and civil society. And scale up public climate finance to enable a just transition and real support for adaptation and addressing loss and damage – by making polluters pay. The recent International Court of Justice advisory opinion has reinforced the demand for climate reparations. COP30 must open a new era of accountability and justice.
Can UN climate talks drive faster emissions cuts?
Dr Jennifer Allan, senior lecturer in international relations, Cardiff University: The UNFCCC is only as effective as parties allow it to be. The Paris Agreement is working precisely how some feared and how some major emitting countries hoped. It is premised on the promise of transparency: that national reports and the global stocktake, coupled with principles of progression, will – somehow – inspire climate ambition. But transparency is not the same as accountability.
Todd Stern: The Paris regime itself has an important role to play. For starters, the regime needs to develop much more of a broad partnership in the spirit of the 2015 High Ambition Coalition. Part of such a shift will depend on considering whether country emission targets are adequate. Of course, Paris was built on the principle of “nationally determined contributions” and that principle cannot be thrown overboard. But Paris was also built on the promise that it would strive to prevent dangerous climate change, that new emission targets every five years would reflect countries’ highest possible ambition and that global stocktakes would, in fact, take stock.
Claudio Angelo, head of international policy at the Climate Observatory: The “nationally determined” nature of nationally determined contributions (NDCs), and the fact that no assessment of progress is formally done outside the five-year period of the global stocktake, mean that the ambition gap will become more difficult to close the more urgent it becomes to close it. The irony of it is that the Paris architecture was tailor-made to accommodate the idiosyncrasies of the US, which has pulled out of the agreement anyway.
Prof Navroz K Dubash, professor of public and international affairs at Princeton School of Public and International Affairs: A bumper sticker for reform of the UN climate talks might read: “Less talk of ambition; more action on implementation”. An “ambition-first” approach rests on extracting national statements of emissions reduction intent, leveraging these up through country “naming and shaming” and strengthening compliance through enhanced accountability. But the conditions are not favourable for this approach. National politics rarely privilege emissions reductions over other objectives and global politics is increasingly non-responsive to climate shame. By contrast, the conditions for a “learning-by-doing” approach based on on-the-ground implementation appear brighter. Many countries are experimenting with pragmatic efforts to turn their economies in low-carbon directions.
Todd Stern: There is nothing about the nationally determined character of country pledges that says countries cannot be questioned, prodded and critiqued. Protecting thin skin is not as important as protecting a liveable world.
Prof Navroz K Dubash: How might global talks enable learning by doing, rather than doubling down on ambition-first approaches? NDCs could be liberated to be templates for experimentation rather than rigid bases for accountability alone. Detailed sectoral low-carbon development pathways would highlight country commonalities, reveal productive scope for international cooperation and incentivise finance…A renewed international process should be focused on the hard, detailed work of enabling low-carbon, resilient development transitions and less on extracting statements of intent.
Kaveh Guilanpour: [We should] move to an approach where progress is measured predominantly by the impact of implemented national level policies, not NDCs on paper. Focus as much on enhancing international cooperation to deliver implementation as on increasing formal ambition on paper through NDC target-setting.
How could COPs ensure broader accountability?
Paul Watkinson: The biggest opportunity to support implementation is outside the formal process, putting order and structure into the “action agenda”. It has grown enormously in recent years and there have been many valuable initiatives…But there has been insufficient continuity and not enough follow-up and tracking to ensure that what is announced and promised is delivered. That is why I welcome the proposal of the incoming Brazilian COP30 presidency to structure the action agenda around six broad themes, drawn from the outcomes of the global stocktake, including a cross-cutting theme around enablers including the vital role of finance. They have the power, in close coordination with the high-level champions, to relaunch the action agenda on stronger foundations that could serve for years to come.
Dr Jennifer Allan: Within the negotiations, there is a glaring need to track the many commitments made outside of the regular negotiation process, either in presidency-led declarations or cover decisions. A central, publicly available hub needs to collate these promises and track progress. Presidencies may broker these commitments, but have few incentives to follow up on them.
Bernice Lee: What can – and must – change is how the system functions. Every decade or so, the climate regime has adapted – from Kyoto’s top-down legalism to Paris’s nationally determined flexibility. These shifts were not just philosophical, they also enabled new capacities. The collapse in Copenhagen helped catalyse renewable energy investment plans, while Paris introduced NDCs. The next phase must embed delivery and equity more deeply into the process including, for example, mechanisms aligning corporate transition plans with country transition, national policies and sectoral pathways. The outcomes of any reform process should mean fewer theatrics, earlier decisions and sharper accountability. All of this would enhance not only country but also public engagement, as well as the credibility of the global climate process.
Harjeet Singh: Rather than catalysing ambition, the Paris Agreement has been used by developed countries to shirk their historical responsibilities…It is not the Paris Agreement or the UNFCCC that failed – it is rich countries that undermined the system to protect polluters and preserve an unsustainable growth model. True reform begins with accountability. Wealthy nations must be held responsible for their historical emissions and must pay for the loss and damage they have caused.
Sandrine Dixson-Declève, honorary president at the Club of Rome and executive chair of Earth4All: Strengthen climate target enforcement through scientific oversight, peer review and robust reporting – ensuring governments, COP presidencies and corporations are held accountable. [There should be] a permanent scientific advisory body within the COP. Science must be central to negotiations, with all delegations regularly briefed on the latest data around risks, equity, solutions and scenarios.
Prof Navroz K Dubash: Ambition and implementation can be complementary, but they are not necessarily so. The former is driven by a relentless focus on emissions, comparability in emission pledges and building accountability. The latter is enabled by linking climate to other objectives, seeking country-specific formulations that buy political support and flexible experimentation that allows for learning from failure. Being more, not less, in the sectoral weeds might reveal opportunities not apparent from the stratospheric heights of climate negotiations. Well-developed, home-grown visions of sustainable futures are the most robust basis for developing countries’ legitimate claims for finance and other support.
Do UN climate talks need majority voting?
Erika Lennon, senior climate attorney at the Centre for International Environmental Law: Voting is the elephant in the room. The parties to the UNFCCC have never been able to adopt the “rules of procedure” because they cannot agree on the provision related to voting in the absence of consensus. Instead, they proceed meeting after meeting using them as “draft rules of procedure”. This has created a race to the bottom whereby countries that want to stall progress can do so. For 29 years, other parties have had to agree to the lowest common denominator in the name of consensus.
Claudio Angelo: The decision made in 2023 to “transition away from fossil fuels” needs both fleshing out and monitoring, but it is nowhere to be seen in the formal negotiations towards Belém. Such omissions reflect one fundamental problem of the UNFCCC and one fundamental flaw of the Paris Agreement: the consensus rule. Some countries are now shamelessly backtracking on their previous commitment and saying that any mention of cutting back on fossil fuels anywhere is a red line for them…A handful of countries are holding the future of humanity hostage because they can block whatever they want [due to the consensus rule]. Even COP presidencies that do want to move the agenda forward are afraid to be bold, lest “the process should collapse”. But a process that is unfit for purpose might as well collapse.
Christiana Figueres: In the context of the formal negotiations, we could reconsider our tradition of having to adopt all decisions unanimously. UNFCCC procedures require consensus for the adoption of decisions, not necessarily unanimity. The difference is important and admittedly challenging to manage, but worth examining.
Erika Lennon: The fix would be to adopt the rules of procedure, including the paragraphs on voting. The UNFCCC would then join many other multilateral environmental agreements – and its own financial instruments – that sometimes use majority voting.
Bernice Lee: In recent months, many well-meaning critics have called the UN multilateral climate process broken, arguing it should be dismantled and replaced, but with no viable alternatives waiting in the wings. Reforming core procedures – such as introducing majority voting or amending the convention – would require agreement from three-quarters of countries, followed by domestic ratification. Even without today’s fractured geopolitics, this would be a tall order.
What should the role of the COP presidency be?
Dr Monserrat Madariaga Gomez de Cuenca: [COPs should] avoid adding more pressure by clarifying duties and processes for the COP president. Rules of procedure simply give the COP president the power to formally conduct the negotiations, which should be done in a neutral manner. Increasingly, we see COP presidents setting exceedingly ambitious plans for their respective COPs. Ideas of “success” and “legacy” permeate what should be a facilitative role towards the collective progress of UN climate talks. COPs finish with statements and reports of achievements that do not reflect the actual progress. Reviewing the conduct of negotiations and the role and expectations of COP presidencies could help in restoring some of the damaged trust in the process.
Prof Thomas Hale, professor in public policy at the University of Oxford: The “action agenda” needs to escape the “boom-bust” cycle that shifting presidencies and high-level champions have imposed on it, in which new announcements trump delivery. The COP30 presidency has laid out a positive approach here, but the acid test lies in making it real.
Sandrine Dixson-Declève: Only countries with high climate ambition should be eligible to host COPs.
Li Shuo, director of the China Climate Hub at the Asia Society Policy Institute: Instead of – or alongside – three more paragraphs specifying how the world will “transition away from fossil fuels” or “triple renewable energy”, how about three renewable projects in the COP host country, to be announced in conjunction with the climate summit?…Efforts to advance the implementation agenda through additional multilateral rulemaking and COP decisions risk missing the point. The COP presidency…could showcase a handful of large‑scale renewable energy projects in their own countries, backed by concrete financing. Such a “trade fair” function of the COP would help bridge the widening gap between what is agreed at COPs and what is happening on the ground.
Do fossil-fuel companies have too much influence?
Erika Lennon: The fossil fuel industry’s survival depends on the UNFCCC’s failure, as meeting the goals of the UNFCCC and Paris Agreement undeniably means phasing out fossil fuels. It is therefore no wonder that, since the beginning, fossil-fuel industry lobbyists have been present at COPs and working to undermine ambition.
Dr Jennifer Allan: Presidencies have much to answer for and can be key to raising accountability. COP is becoming the new Davos: a place for billionaires to meet, without scrutiny of their activities or announcements. This must end. Presidencies should revoke invitations to [Amazon chief executive] Jeff Bezos and others who have been offered high-level platforms.
Erika Lennon: Parties could adopt a conflict-of-interest policy to, at the very least, make [fossil-fuel lobbyists’] influence transparent and subsequently exclude those who aim to unduly influence the process. Parties, including the presidency team, could refuse to give them badges…In addition, they could end greenwashing at COPs in the form of corporate sponsorships and pavilions.
Are COPs too big?
Prof Thomas Hale: COP is both too big and too small for an era of implementation. Its cost and complexity eat up scarce resources. Meanwhile, it creates a gravity well that warps the climate community’s work into an annual rush to the end of the year…At the same time, even the biggest COPs are puny compared to the problem. Climate change demands action from all of society…In this complex system, the UNFCCC process plays the critical function of setting agendas and goals. No other body has the multilateral legitimacy to serve as a lighthouse.
Dr Jennifer Allan: Climate summits could shift from a talkshop to a demonstration of leadership if invitations are only extended to countries that have submitted and maintained more progressive NDCs and are implementing them.
Prof Thomas Hale: We need COPs to be everything, everywhere, all at once. Alongside a single, two-week meeting in one place, we need lots of smaller, focused meetings in many places. Instead of an intergovernmental process that talks about action, we need to fully shift the “action agenda” into the heart of the UNFCCC. The good news is that the elements of this shift are already well in motion, with more and more cities hosting “climate weeks”…Regional meetings with more flexible formats reach more people, in a more targeted way, much more cheaply and efficiently than a COP.
Dr Jennifer Allan: I’ve been researching the role of side events, pavilion activities and Global Climate Action Hub panels in the “expo” that now dominates COP space and participation opportunities. There has been a decided shift, from a smaller number of events focused on negotiation and implementation to a huge array of panels showcasing new initiatives or national actions. It is about what is new, not following up on what has been agreed. Side events and Global Climate Action Hub events could shift focus under the secretariat and the high-level champions. Pavilion spaces could be reserved for those who can demonstrate that their presence will advance climate action.
Sandrine Dixson-Declève: COPs must evolve from negotiation-heavy forums to more frequent, smaller, solution-focused meetings centred on progress and implementation, with broad stakeholder participation.
How could COP participation be improved?
Erika Lennon: Civil society, youth, Indigenous peoples, women, local communities and people with disabilities, among others, have increasingly faced shrinking civic space in the UNFCCC process. They have to fight to have their voices heard, to be present in the rooms where decisions happen, for access to information and open decision-making, and to assemble peacefully.
Shreeshan Venkatesh, global policy lead at Climate Action Network International: Structural barriers…undermine inclusivity and equitable participation in UNFCCC meetings, from the high cost of accommodation at COPs to discriminatory visa practices and shrinking civil society quotas. These barriers must be dismantled to ensure all parties and stakeholders can participate fully and on equal terms.
Erika Lennon: Parties should incorporate and support participation not only at COPs, but also in climate action and decisions on the ground. They can do this by creating space across all agenda items to hear from rightsholders and ensuring human rights and civic space are guaranteed during all negotiations.
Shreeshan Venkatesh: Civic space and freedoms are under threat, even at COPs. Host agreements must guarantee freedom of speech, assembly and accessibility, backed by an independent body to address violations.
How can COPs drive change outside the UN process?
Sandrine Dixson-Declève: COP must transform from a forum of negotiation to a platform of delivery, inclusion and accountability, anchoring climate action in the lived realities of people and the demands of science.
Kaveh Guilanpour: There should be a thorough and honest analysis of the value add of the UNFCCC process and what is best left to other fora.
Christiana Figueres: While some negotiations remain necessary, the most urgent action has shifted to implementation in the context of market forces and climate economics. There is no doubt that civil society, businesses, cities and communities are moving faster than governments. These actors, traditionally considered and labelled as mere “observers” in the formal UNFCCC space, have become the true engines of transformation. One could consider the pros and cons of creating a semi-detached “real world” space alongside COP – one that amplifies their progress, showcases innovation and feeds actionable insights back into the formal process.
Todd Stern: The Paris regime has a role to play in encouraging and tracking strong action outside its purview. This includes the public and private sectors working together on rapid decarbonisation and on unlocking the kind of large-scale investment needed for countries in the global south to build sustainable and resilient economies.
Shreeshan Venkatesh: The UNFCCC, and other multilateral fora that have become central to the formulation and implementation of climate policy and international cooperation, must align with international law. This includes the recent advisory opinions from the ICJ and the Inter-American Court of Justice, and the obligations they clearly lay out.
Claudio Angelo: [There is] a final, bigger problem, which no UNFCCC reform can solve: the climate regime is a child of the democratic world order and the lynchpin of that world order has become a rogue state. The rise of the far-right and the erosion of democracy are rendering multilateralism itself useless – a world that is unable to stop genocides in Gaza and Sudan can’t solve the climate crisis.

Israel’s bombardment of Gaza during the conflict that broke out in October 2023 has wrecked progress towards adapting the enclave to climate change and left two million Gazans vulnerable to heatwaves, drought and disease, the Palestinian Authority (PA) said in a new climate plan submitted to the United Nations.
Palestine’s third nationally determined contribution (NDC), uploaded to the UN climate body’s website this week, says that while “the aggression on the Gaza Strip did not make the climate worse”, “it removed the housing, water and sanitation systems, health facilities, energy networks, roads and livelihoods through which people absorb a climate they were already struggling with.”
The 91-page document lists the types of infrastructure it says Israel has destroyed and notes how the destruction will worsen the impacts of climate change. It says the bombing of hospitals and rising hunger have make it harder for Gazans to cope with the health impacts of climate-driven heatwaves and waterborne diseases.
The destruction of water tanks, boreholes and desalination plants, meanwhile, have left Gazans struggling with the effects of water shortages and drought, while mass unemployment reduces people’s ability to afford climate-driven price rises. The erasure of most of the Strip’s homes makes it more difficult for people to avoid the sun’s increasing heat, the NDC said.
Many Gazans are now living in the ruins of collapsed buildings or in makeshift shelters and tents that offer little or no protection from high temperatures.
Palestine’s previous goals to cut emissions and adapt to climate change in Gaza, expressed in its last NDC five years ago, were based on a pre-war baseline that “no longer describes anything that exists”, the NDC says. Progress made since 2021 has now been destroyed, it adds.
Green reconstruction of Gaza
Instead of continuing to aim for these adaptation and emissions-reduction goals, the PA is now calling for the green reconstruction of Gaza. It says buildings should be constructed again in an energy-efficient manner with solar panels and served with modern water, waste and transport systems.
While the PA, controlled by the Fatah political party, continues to claim legitimate control of Gaza, the strip was effectively governed by Fatah’s rival Hamas between 2007 and the recent war. Control is now split between Israel and the political wing of Islamist militant group Hamas, after a US-backed ceasefire took effect in October 2025, although a UN-backed committee plans to take over.

More support needed to power Africa’s food systems with renewables, experts say
Renewable energy could help African food businesses boost productivity and competitiveness, but the upfront cost, fragmented markets and limited financing stand in the way
The United Nations, European Union and World Bank have jointly estimated that Gaza needs $71.4 billion of investment in the next two years to recover and build back. This process should be Palestinian-led, they said in April.
But US President Donald Trump has said the US should “take over” and “own” Gaza and redevelop it as the “Riviera of the Middle East”. Israel’s right-wing prime minister Benjamin Netanyahu has said that Israel should control the territory with civil administration managed by Palestinians favourable to Israel.
With occupation, targets conditional
In the other part of Palestine, the West Bank, the Palestinian Authority carries out some government functions, but ultimate control rests with Israel, which has occupied the West Bank since 1967.
Because Israel controls planning in most of the West Bank, the NDC argues that the PA cannot pursue all the climate projects it wants. In addition, Israel restricts the movement of PA officials, making data collection difficult, and controls the West Bank’s electricity supply meaning that the PA cannot control whether it comes from dirty or clean sources of energy.
Given this situation, the NDC says that all of Palestine’s new climate targets are conditional but it will aim to reduce emissions 12.8% below a business-as-usual baseline by 2035 and 17.1% by 2040. If the Israeli occupation ends and Palestine regains full sovereignty over its land and resources, it will aim for reductions of 15.1% and 19.1% by 2035 and 2040 respectively under an “independence pathway”.
That could allow, for example, for greater electrification and reducing emissions per unit of growth, the document said.
To achieve the 2035 emissions-reduction target and adapt to the impacts of climate change, the PA says it needs $8.6 billion in total. This funding would be spent on measures like encouraging solar farms and rooftop solar and scaling up solar water heating to cover four-fifths of households. To complement the planned increase in solar power, the authority wants to modernise the electricity grid and install battery storage.
In the transport sector, it aims to promote the uptake of electric vehicles, develop bus rapid transit corridors and scrap old polluting trucks and buses. In Gaza in particular, it wants to deploy 66 electric buses when the conflict ends.
To adapt to climate-driven drought, the NDC includes initiatives to reuse wastewater through treatment plants, build desalination plants in Gaza to remove salt from seawater, and promote irrigation for farmers.
The new climate plan was prepared by Palestine’s Environment Quality Authority, with support from the United Nations Development Programme and the governments of Britain and Spain.
The United Nations recognised Palestine’s statehood in 2012 and it joined the UN’s climate convention and signed the Paris climate agreement – which requires countries to submit more ambitious NDCs every five years – in 2016.
The Israeli foreign ministry did not respond to a request for comment. But in late 2024, then Israeli climate envoy Gideon Behar told Climate Home News that the war and the resulting environmental destruction in Gaza was the fault of Hamas.

Palestine: Israel’s bombing has left Gaza vulnerable to climate change
Solar power generation in the UK reached a new record over the summer of 2026, as temperatures across the nation soared, according to new analysis by Carbon Brief.
Collectively over June, July and August, solar farms and rooftops generated 8.8 terawatt-hours (TWh) of electricity in the UK*, as shown in the chart below.
Speaking to Carbon Brief, Chris Hewett, chief executive of trade association Solar Energy UK welcomed the new record, adding that it was driven by “clear skies and continued growth in deployment”.
This surge in generation took place amid the hottest summer on record in the UK, with five heatwaves between May and August.
Summer 2026 was the sixth sunniest on record, with more than 620 hours of sunshine, according to the Met Office. England and Wales – which experienced the most extreme heat – saw their second-sunniest summers on record.
June 2026 was the hottest June in England since records began in 1884, according to Met Office data, while Wales and the UK as a whole experienced their second-warmest June.
It was the driest July for England and Wales since records began in 1836, with some parts of London seeing no rain at all in the month, while Wisley in Surrey had no rain for 62 days.
In England, temperatures peaked at 38.1C at Kew Gardens in London on 13 August.
According to the Met Office, this summer’s record mean temperature was made 130 times more likely by climate change.
Amid these hot and sunny months, solar power generation increased 23% from the same period in 2025. This is double the level of solar generation over the summer of 2021, according to Carbon Brief analysis.
While solar panels can be affected by periods of extreme heat, the longer hours of daylight and higher levels of irradiation over the summer more than offset any efficiency losses.
June, July and August all saw solar set new monthly records for solar generation – July saw the highest solar generation in a calendar month ever, with 3.3TWh meeting 15% of overall electricity demand for the month.
As of the end of August, the total UK solar generation in 2026 stood at 17TWh – 13% higher than the same point in 2025.
The number of solar farms and rooftop installations has grown substantially in recent years, helping to boost generation. Domestic rooftop solar accounts for around 29% of total capacity.
In 2025, the UK’s solar capacity reached 21 gigawatts (GW) by the third quarter of the year, according to UK government figures. This is a jump of 3GW, or 18%, year-on-year, as Carbon Brief reported in January.
(Capacity is the maximum output possible from an electricity generation, whereas generation is what was produced over a certain time period, such as a day, month or year.)
According to the University of Sheffield, the installed solar capacity is now nearly 24GW.
This includes nearly 172,000 solar installations that have been fitted across the UK since the start of 2026, according to recent government figures. In July alone, more than 19,800 rooftop solar panels were installed – the equivalent of one installation every two minutes.
In total, nearly 1.7m households in the UK now have solar panels installed.
Over 26 heatwave days this summer – periods of at least three days when temperatures exceed the Met Office’s county-level heatwave temperature threshold – UK households with rooftop solar panels avoided an estimated £86.7m in electricity costs, according to analysis by Utility Bidder.
Talking about the surge in solar generation this summer, Hewett says:
“[It] not only kept bills down for people with solar and batteries in their homes, but helped keep overall power prices much lower than they would have been if Britain had been relying on more gas generation during the day”.
Despite the record generation, no new half-hourly solar power output record was set in the summer of 2026. This still stands at 15.2 megawatts (MW) on 23 April 2026.
* This article refers to the UK throughout, but strictly relates to the island of Great Britain, made up of England, Scotland and Wales. Northern Ireland is part of the separate, all-Ireland electricity system.

Farmers around Europe are dealing with the aftermath of a summer of extreme heat, drought and wildfires that were exacerbated by climate change.
Human-caused climate change is increasing the severity and likelihood of many extreme weather events around the world, which is increasing volatility for food producers.
This summer resulted in, for example, shrunken potatoes in the Netherlands, reduced carrot harvests in France, dried-up rice fields in Italy and scorched olive groves in parts of the Mediterranean region.
Global food prices are currently at their highest level since early 2023 due to “heatwaves and energy price dynamics”, according to the UN Food and Agriculture Organization.
Other factors such as blocked fertiliser supplies in the Strait of Hormuz and high fuel costs have also played a role in this year’s agricultural outputs.
In the six charts below, Carbon Brief provides a snapshot of the impact this summer’s extremes are considered to have had on crop production and yields across Europe.

1. Most EU countries expect to see declines in cereal production this year
France, in particular, will see heavy losses in the amount of cereals – such as wheat, barley and oats – it produces this year, according to European Commission data.
French cereal production is expected to drop by almost 8 megatonnes (Mt) in 2026, compared to 2025.
The chart above shows that most European countries, aside from Bulgaria, will also see production losses this year.
Germany is due to see the second-largest losses in production, dropping by almost 4Mt compared to 2025.
Prof Til Feike, a cropping systems expert at the Julius Kühn-Institut, says many areas in Germany and Austria, as with other parts of Europe, have been “hit hard by a long-lasting dry period in combination with record-high heatwaves”.
This has resulted in dry grassland for animals and lower yields of maize, which is a “key fodder crop” for livestock. He tells Carbon Brief:
“In the long run, farming must adapt better to more extreme weather conditions, not only heat and drought, but also prolonged wet periods. So, there is no one-fits-all solution for climate change adaptation.”
2. Most countries are recording reduced crop yields
Heat and a lack of water have “substantially worsened” crop expectations this summer in western and most of central Europe, according to a recent bulletin from the EU Joint Research Centre.
Yields are expected to be “significantly reduced”, with local crop failures “likely” in areas such as France, southern Germany, northern and central Italy, and Hungary, it added.
The chart below shows that yields of cereal grains – which, here, refers to the tonnes of a grain grown per hectare of land – are expected to fall in most EU countries in 2026.
Slovakia, Austria and Hungary are expected to see the largest declines in cereal yields, reducing by more than one tonne per hectare in 2026 compared to 2025.
The recent EU bulletin noted that irrigated crops performed well in Portugal this summer – the country with the largest yield increases. Other crops relying on rainfall showed growing signs of heat stress, it added.
3. Around €2bn worth of cereal losses after June heatwave
The record heatwave that hit many parts of Europe in June contributed to an estimated €2-2.3bn in cumulative grain production losses, as shown in the chart below.
The intense June heat in western Europe would have been “virtually impossible” just 50 years ago, according to a rapid climate attribution study. It was the region’s hottest June on record.
The Energy & Climate Intelligence Unit (ECIU) thinktank analysed June and July 2026 grain forecasts from Coceral, a European grain traders association.
ECIU estimated lost supply by multiplying the change in tonnes of grains between these two months by prices for harvest delivery in 28 European countries.
Major grain producers France, Germany, Hungary and Spain accounted for 86% of the lost revenue, according to the ECIU.
Extreme heat is also expected to have a wider economic impact across the continent. Analysis from Triodos Bank found that this summer’s extreme weather could reduce the EU’s gross domestic product (GDP) by around 1% this year, or around €180bn.
4. UK yields of wheat, barley and oats are all due to drop in 2026
If current trends continue, the average yields for cereals and oilseeds will result in the UK’s worst harvest since detailed records began in 1984, according to ECIU.
Barley yields could fall by 15%, oats by 14% and wheat yields by 6% year-on-year, according to 2026 harvest surveys from the Agriculture and Horticulture Development Board, a non-departmental public body that provides agricultural data to the UK government.
ECIU said that, even if the situation improves, this year is still expected to be one of the five worst harvests on record. This means that four of the five worst harvests in the UK have occurred in the past decade.
Consumers will likely see higher prices and/or smaller vegetables in supermarkets as a result, Tim O’Malley, chairman of UK company Nationwide Produce, told BBC News in August.
Other crops, such as berries, have grown successfully in the extreme heat. But the Guardian noted fears this could dip later this year “as plants become exhausted from heavy cropping during the heatwave”.
5. Maize production in France is due to hit a four-decade low
France has been acutely affected by this summer’s extreme weather, with more than 7,300 excess deaths during heatwaves and a record number of weather stations recording temperatures of above 40C.
The country is the EU’s largest agricultural producer, but heat, drought and wildfires have affected many crops.
The chart below shows that maize production is set to drop by more than one-third (35%) year-on-year.
This could result in France’s lowest maize production since 1980, according to data from Agreste, the country’s agriculture ministry’s statistics service.
Due to the heat, “record-early” grape harvests have also been recorded in various parts of the nation since mid-July, reported Le Monde. In some cases, this means “smaller, less juicy grapes, which will yield less wine”, explained the newspaper.
6. Declines in EU grains since 2025
Overall in the EU, data and projections indicate declines in the output of cereal grains this year.
Cereal production is set to fall by 9% compared to 2025, according to the European Commission.
Just one year in the past decade – 2024 – recorded lower production levels.
Maize production is set to be particularly affected, with projections indicating a 13% drop, to 52Mt – the lowest level in the EU since 2007.
