A major fund for biodiversity remains starved of resources more than five months after its launch – with no money yet put forward by the large companies who could contribute.
The “landmark” Cali Fund – which could generate billions of pounds each year – was created under the UN Convention on Biological Diversity (CBD) at the COP16 nature negotiations in Cali, Colombia last autumn.
Countries agreed that certain companies “should” pay into the fund, but this is not legally binding and donations are, ultimately, voluntary.
The fund is designed to be a way for companies who rely on nature’s genetic resources to share some of their earnings with the developing, biodiverse countries where many of the original resources are found.
Companies use genetic data from these materials to develop products, such as vaccines and skin cream.
Emails released to Carbon Brief under the UK Freedom of Information (FOI) Act show that companies were contacted with opportunities to be involved in the Cali Fund before its launch in February 2025.
Pharmaceutical giant AstraZeneca did not take up an offer from a UK government department to be a “frontrunner” in committing to donate to the fund, the emails show.
GSK, another major company in the sector, also did not confirm its position.
These are the UK’s two largest pharmaceutical companies and they could each potentially contribute tens of millions of pounds to the fund, based on current guidelines.
Earlier this year, a spokesperson for the CBD said that the first contributions to the Cali Fund could be announced in spring.
One US biotechnology company has pledged to contribute to the fund in the future, but, for now, the fund remains empty.
Company hesitancy could be “driven by industry bodies” who “don’t want unhappy precedents to be set” on the level of funding, a researcher who was involved in the fund negotiations tells Carbon Brief.
Lack of funds
Companies all around the world use genetic materials from plants, animals, bacteria and fungi to develop their products.
There are existing rules in place to secure consent and compensation, if companies or researchers physically travel to a country to gather these materials.
But, currently, much of this information is available in online databases – with few rules in place around the requirements needed for access. This genetic data is known as digital sequence information (DSI).
In an effort to close the loophole, almost every country in the world agreed in 2024 to set up the Cali Fund.
The agreement outlines that large companies in sectors including pharmaceutical, cosmetic, biotechnology, agribusiness and technology “should” contribute to the fund to share back a cut of the money they earn from the use of these materials. (See: Carbon Brief’s infographic on DSI.)
However, these contributions are voluntary. Many African and Latin American countries sought a legally binding mechanism around this issue at COP16, but this did not happen.
The fund officially opened at the resumed COP16 negotiations in Rome in February 2025.
With the fund still empty more than five months later, a spokesperson for the CBD secretariat tells Carbon Brief that a US-based biotechnology firm, Ginkgo Bioworks, is the first to “indicat[e] its intention to contribute”.
The CBD, also acting as the interim secretariat for the new fund, “continue[s] to engage with business associations to raise awareness and secure funding”, the spokesperson says.
They add that a decision-making body and a steering committee have been set up.
The CBD received “positive feedback and engagement” from companies about the fund, the UN biodiversity chief Astrid Schomaker said in a February press conference. She added that donations were expected “very soon”, but not in “massive numbers”.
Carbon Brief contacted Ginkgo Bioworks for comment, but did not receive a response in time for publication.
‘Frontrunner’ contributors
Through an FOI request, Carbon Brief received email correspondence between the UK Department for Environment, Food & Rural Affairs (Defra), major pharmaceutical companies AstraZeneca and GSK, and trade group the Association of the British Pharmaceutical Industry (ABPI) between August 2024 and April 2025. (Carbon Brief has uploaded the FOI documents it received to a Google Drive folder.)
A representative from Defra told AstraZeneca in December 2024 that they were contacting a “select number of companies that will likely be frontrunners with the Cali Fund and make contributions – leading the way for others to follow suit”.
The Defra employee said that they had received “some positive signals from these companies” and asked if AstraZeneca was interested in “demonstrating commitment in this start-up phase of the fund”. This email said:
“I hope this finds you well – and thanks for joining various calls over the last few weeks on DSI, it’s great to have you involved. I know that AZ have been really forward leaning on ABS issues in the past (including under your leadership) and now that we have the Cali Fund for benefit sharing from the use of DSI, I wondered if we might pick up the conversation on any role AZ might be able to take as an early mover in the ABS world?
“We are beginning to have conversations with a select number of companies that will likely be frontrunners with the Cali Fund, and make contributions – leading the way for others to follow suit – and we have had some positive signals. Do you think there might be any interest from AZ in demonstrating commitment in this start-up phase of the Fund? If it would be helpful to have a conversation to chat through, please do let me know and I’d be super happy to set something up.”
The AstraZeneca representative responded to say the company was “in the process of conducting an assessment to define our position” on the fund and that they would “welcome a conversation” when this concluded.
A Defra official contacted the company again in early January to say the government was preparing meetings between a member of the CBD secretariat and several businesses “that have shown some interest in leading others by making the first contributions to the fund”.
They asked if AstraZeneca was interested in attending this meeting. The company declined, but said it would be interested in future discussions.
An AstraZeneca spokesperson declined to respond to Carbon Brief’s questions, but Carbon Brief understands that the company is still reviewing its position on the fund.
Similar exchanges took place between representatives from Defra and GSK ahead of the Cali Fund launch.
GSK was invited to the same January meetings, but the company said nobody was available to attend. A Defra official contacted GSK in February to update on progress with the fund, outlining that it would be launched in Rome, “accompanied by a platform for announcements and press coverage”.
The Defra official asked GSK to let them know “if you think there might be any opportunities for GSK – we would obviously love to add your voice to the positive coverage”. The email read:
“As a broader update, we are still expecting the Fund to formally launch in Rome at COP16.2, and that will be accompanied by a platform for announcements and press coverage. We are also working with another CBD Party to explore the option of putting on some kind of reception for those businesses that are leading the way together.
“Please do let me know if you think there might be any opportunities for GSK – we would obviously love to add your voice to the positive coverage!”
They also asked if GSK would like to see a draft version of a press release from the CBD about the launch of the Cali Fund, along with other businesses “that are interested in being part of the launch”.
(The Cali Fund launch press release did not contain any quotes or donation announcements from companies.)
GSK said that it was “awaiting further clarification on a number of key elements” before making a decision on the Cali Fund and would respond “in due course”.
The company “support[s] the intent” behind the fund, a spokesperson tells Carbon Brief, adding:
“We’ll make a decision regarding voluntary contributions when more information becomes available about how the Cali Fund sits alongside other multilateral mechanisms.
“GSK was one of the first companies to publish a nature strategy and we continue to work on delivering our plan to address our nature impacts and invest in nature protection and restoration.”
A Defra spokesperson tells Carbon Brief:
“Nature underpins everything and those who profit from the use of genetic data should pay nature back. The Cali Fund provides the route for companies to do that.
“The government is committed to continuing to engage constructively with industry to drive contributions and champion the fund to protect nature and sustain innovation.”
The UK and Chile recently launched the “friends of the Cali Fund” group, which “brings together” governments and businesses to “champion” benefits sharing, a UK government statement said. Norway, Germany, the Netherlands and Colombia have also joined this group.
UK companies could contribute £64m
Contributions to the Cali Fund are voluntary. They will depend on whether companies that rely on the use of genetic data will then admit to using genetic materials and decide to pay into the fund.
The agreement behind the fund, which is not legally binding, outlined that companies “should” contribute 1% of their profits, or 0.1% of their revenue. These are an “indicative rate”.
Words that are more binding, such as “will” and “shall”, were included in non-paper negotiation texts during the talks. But the final agreement referred to a fund that companies “should” pay into, which was criticised by some experts at the time.
At least half of the money raised will go towards meeting the “self-identified” needs of Indigenous communities in developing countries, particularly women and young people.
The overall fund could generate between $1bn and $10bn each year, according to a 2024 analysis requested by the CBD.
The cache of information released under FOI to Carbon Brief also includes a report on the impacts of a mandatory payment for using digital sequence information, which was prepared for Defra by consultancy company ICF in July 2024.
It estimated that a mandatory 1% levy on the profits of large UK companies “who are considered DSI-dependent” could generate nearly £64m ($85m) for the fund.
The report compared three different benefit-sharing mechanisms around genetic data: a mandatory levy on UK profits/revenues; a flat fee; or a subscription fee.
All options would negatively impact on “innovation” to varying degrees, the report said, but a mandatory levy on profits was found to have the “least negative impact on competition and innovation”.
During the Cali Fund negotiations last October, the Guardian reported that AstraZeneca “said it may cut jobs” in the UK, if such a levy was introduced. An AstraZeneca spokesperson denied the comments, the newspaper said.
Based on the “indicative” contribution rates of 1% of profits or 0.1% of revenue, Carbon Brief estimates that AstraZeneca could potentially contribute as much as £41-66m ($54-88m) and GSK £31-35m ($41-46m) each year to the fund.
AstraZeneca reported revenue of £41bn ($54bn) and £6.6bn ($8.7bn) in profit before tax in 2024. GSK’s revenue that year was around £31bn ($40bn) and its pre-tax profit was £3.5bn ($4.6bn).
Lobbying concerns
At COP16, many observers were concerned about industry lobbying around digital sequence information.
DeSmog analysis of COP16 attendees highlighted the presence of big pharmaceutical companies, powerful industry groups and agribusiness at the talks.
The International Federation of Pharmaceutical Manufacturers and Associations (IFPMA), a global pharmaceutical trade group, said it had “serious concerns” about proposals around the fund at the start of COP16. The group said it would result in “regulatory and financial barriers that would stifle innovation, delay R&D [research and development] and complicate compliance”.
The emails obtained by Carbon Brief show that, in August 2024, a GSK representative told Defra that the company believed proposals for a “simplistic payment mechanism based on revenues would be disproportionate and could hinder the development of new medicines and vaccines”. This email said:
“You were asking for views on the call, so I also wanted to take the opportunity to share GSK’s perspective at this time. We are supportive of a practical and fair multilateral mechanism for benefit-sharing from the use of digital sequence information on genetic resources. The criteria for this mechanism listed in decision 15/9 are particularly important, specifically the fact that it must not hinder research and innovation.
“We are concerned that the current proposals for a simplistic payment mechanism based on revenues would be disproportionate and could hinder the development of new medicines and vaccines. We would support the consideration of other models, for example a subscription model whereby organisations that access open source DSI databases make a contribution to the global fund.
“This would have the benefit of broadening the base of contributors. Tiers could be established based on size of organisation, so that the contributions were proportionate and fair.”
The FOI release also shows that ABPI chief executive, Dr Richard Torbett, wrote a letter to UK nature minister Mary Creagh on 17 October 2024, a few days before the COP16 summit began.
He “urge[d]” the government to not agree on the details of a fund “until more work has been conducted to understand the implications of proposals”.
Torbett said that, if this was not possible, the ABPI wanted the government to support an option put forward by Japan and South Korea to introduce a voluntary funding mechanism.
Hesitancy potentially ‘driven by industry bodies’
In a statement after COP16, the IFPMA’s director general, Dr David Reddy, said the decision creating the Cali Fund “does not get the balance right between the intended benefits of such a mechanism and the significant costs to society and science that it has the potential to create”.
The FOI release obtained by Carbon Brief includes a 20 March 2025 document from the ABPI discussing possible future changes to the fund.
The group said the fund “contains and omits several features which make it unlikely to attract significant contributors”. The ABPI “cannot over-emphasise the importance” of the fund being voluntary, the document said, with companies “free to decide” if and how much they want to contribute.
The ABPI urged the UK to discourage any country-level implementation of the COP16 digital sequence information agreement, arguing that “conflicting” action on a national, rather than global, level would “reduce the (already weak) incentives to contribute to the Cali Fund”.
The ABPI also criticised the agreed 0.1% and 1% contribution rates for companies, saying they are “regarded by industries generally as being unrealistic and likely to impact innovation”.
The ABPI declined to respond to Carbon Brief’s questions and referred Carbon Brief to the global trade group, the IFPMA. A spokesperson for the IFPMA also declined to respond to questions and pointed towards the company’s public statements on the issue.
Dr Siva Thambisetty, an associate professor of law at the London School of Economics and Political Science and project lead on an ocean biodiversity research group, believes the first contribution to the fund is a “prize that’s just waiting to be won”. She tells Carbon Brief:
“It would be an absolute coup for a responsible DSI company to be the first to make a contribution to the Cali Fund. Investors should be very interested in that company, for instance.
“We’ve got to move to a biodiversity market where investors are asking whether companies they invest in are contributing to remedy and repair at a global level through appropriate monetary benefit sharing.”
Thambisetty believes that this is “low-hanging fruit”, but acknowledges that companies have varying opinions on the fund and that the “majority might be unsure how to deal with this”. She adds:
“I think the hesitancy is mostly being driven by industry bodies because they don’t want unhappy precedents to be set. There is a collective action problem and the first company to break cover will be sending a signal that will be received differently by different people.”

Revealed: ‘Cali Fund’ for nature still empty as emails show industry hesitation
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.
