Mads Christensen is the Executive Director of Greenpeace International.
In a year that marks the UN’s 80th anniversary and 30 years since the first UN climate summit, the global multilateral system tasked with preventing disaster remains incapable of delivering the speed and scale of change we need — even as the available carbon budget shrinks and tipping points loom.
At the heart of this paralysis lies the broken consensus model of the United Nations Framework Convention on Climate Change (UNFCCC). Every decision must be agreed to by all 198 Parties. In practice, this means even one country can block the rest of the world from acting — and a number often do.
We’ve seen this play out repeatedly: oil-saturated nations derailing fossil fuel phase-out language, rich nations delaying climate finance, and authoritarian regimes using geopolitics as leverage to stall negotiations. But it’s not just fossil fuel exporters or autocracies causing the deadlock.
The result is a ‘race to the bottom’ that rewards inaction, dilutes ambition, and sidelines the world’s most vulnerable. It’s time to end this cycle. It’s time for majority voting at UN climate summits and to reform what are now outdated governance structures.
System is failing vulnerable nations
The Paris Agreement, adopted in 2015, was a diplomatic breakthrough — but it lacks enforcement mechanisms. Implementation has stalled. Emissions are still rising. Fossil fuel production is expanding, and we are hurtling toward 3.1°C of warming by the end of the century.
In short: the system is not delivering and the world cannot afford another lost decade of incrementalism.
This isn’t just a technical problem — it’s a moral one. The communities most affected by the climate crisis are also those least responsible for causing it. From small island states facing existential sea level rise to millions across Africa and South Asia suffering crop failure, water stress, and energy poverty, the injustice is staggering.

Treaty to protect deep ocean reaches key threshold for entry into force
The High Seas Treaty, now signed into law by 60 countries, is seen as crucial to achieving a global goal of protecting 30% of land and sea ecosystems by 2030
These nations have consistently called for stronger action. But under consensus rules, they are routinely overruled or ignored. Instead, decisions are held hostage by the interests of the few: fossil fuel-producing states, authoritarian governments, and wealthy nations with regressive leadership, like the US under President Trump.
Consensus has become a tool of obstruction. We need a model that actually gives climate justice a chance to prevail — one where the majority can act, and the vulnerable are empowered.
Momentum for reform is growing
The case for majority voting is not just practical — in the light of recent judicial developments, the legal and political implications are being magnified.
In July, the International Court of Justice issued an advisory opinion stating that fossil fuel licensing, consumption, and subsidization could amount to violations of international law and basic human rights. This raises the legal stakes for governments that continue to expand fossil fuel production while obstructing climate negotiations.
Simultaneously, political momentum for UN reform is growing. In a speech this month, Chinese President Xi Jinping proposed a more “just and equitable global governance system” in a pointed critique of institutions dominated by outdated rules and powerful interests.
The UN Secretary-General’s own flagship initiative for global reform, the UN80 process, underscores just how overdue these governance changes are.
The company tracking energy transition minerals back to the mines
Although key reform proposals have been delayed beyond this year’s UN General Assembly, the Secretary-General’s mandate implementation review paints a picture of systemic dysfunction: overburdened mandates, siloed agencies, and an avalanche of reporting with little impact or accountability.
If the broader UN system is struggling to deliver on its own instructions, climate governance must not remain stuck in the same bureaucratic inertia. Majority voting could be the first real test of whether the UN can shift from fragmentation to function.
Brazil’s leadership needed
We must ensure that this momentum is used to strengthen — not weaken — international climate governance and majority voting is a clear and immediate step that can deliver results. The UNFCCC’s draft rules of procedure — pending since COP1 in 1995 — already contain provisions for majority decision-making. Their adoption has been blocked for three decades by countries benefiting from the status quo.
Brazil, as host of COP30 in 2025, has already taken a leadership role by proposing innovations in climate cooperation. In a letter to Parties in May, it floated the idea of an “alignment” of actors and efforts— signals that the country is open to innovations in cooperation that go beyond the consensus trap.
That opening must be seized with the courage to act and this year’s UN General Assembly offers governments an opportunity to push for procedural reform and test majority-backed decisions.
As governments bet on carbon trading, Japan’s early scheme spotlights pitfalls
Brazil’s leadership, and support from a wide coalition of countries in Africa, Asia, Latin America, the Pacific, and progressive EU members, can tip the balance. Multilateralism that cannot function — that enables the few to obstruct the many — is no longer credible and must evolve.
While consensus can remain our preferred approach, where there are a few blockers to the majority, we must instead push ahead with science, justice and majority voting to ensure progress.
This is not unprecedented. Other international bodies, from the World Health Assembly to the International Labour Organization, use majority voting when needed. It’s time the UNFCCC caught up. The climate crisis is the defining challenge of our time.
The world’s people are demanding action, and a majority of nations are ready to respond. But a system where one or two countries — whether fossil fuel powers or political saboteurs like Trump’s America — can block the entire planet from acting is not just undemocratic, it’s deadly.
Let consensus be the starting point. But when the majority are ready, and the stakes are existential, let the majority act. Let the majority decide.

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.

The post Analysis: UK solar power hits record high over summer 2026 appeared first on Carbon Brief.
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
2. Most countries are recording reduced crop yields
3. Around €2bn worth of cereal losses after June heatwave
4. UK yields of wheat, barley and oats are all due to drop in 2026
5. Maize production in France is due to hit a four-decade low
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.
