Key developments
Food systems on the menu at COP29
MITIGATING METHANE: Yesterday was “food, agriculture and water day” at COP29, with a number of new initiatives and updates to existing initiatives announced. Down to Earth reported that more than 30 countries had endorsed the COP29 Declaration on Reducing Methane from Organic Waste, which includes a commitment to including sectoral targets in countries’ climate pledges. It added that the European Commission “welcomed the declaration, but did not endorse the pledge” due to a lack of time to consult with all member states.
PEACE AND HARMONIYA: The COP29 presidency also announced the Baku Harmoniya Climate Initiative for Farmers on Tuesday, in partnership with the UN Food and Agriculture Organization. The Harmoniya initiative has three stated priorities: creating a “streamlined knowledge hub” for improving collaboration and knowledge-sharing; making investment in food systems more attractive to both public and private investors; and empowering women and youth farmers to adapt to climate change. The declaration said: “Given the multitude of initiatives, there is a need for coherence, alignment and sharing of lessons learned to deliver greater impact.” No new commitments or funding accompanied Harmoniya’s release.
CHAMPIONING CHANGE: Food day also delivered an update on one of the key food-systems announcements from last year’s summit, the Alliance of Champions for Food Systems Transformation (ACF) – a group of six countries that had committed to taking stronger action on transforming food systems. During the summit, the ACF released a “progress snapshot” highlighting actions and policies each country had taken towards the priority action areas defined by the ACF. Tanzania confirmed its intention to join the coalition, the Guardian said. Vietnam also reportedly expressed their interest in joining.
AIM FOR THE SKY: Devex reported that the Agriculture Innovation Mechanism for Scale (AIM for Scale) initiative “has introduced its first package of investments”, which amounts to $1bn to strengthen weather forecasting for farmers. This “includes both new and existing investments from a consortium of global partners”, such as the World Bank, the US Agency for International Development and NASA. According to Emirates News Agency, investments in “climate-smart agriculture and food systems innovation” through the wider AIM for Climate initiative total $29.2bn to date. DeSmog previously reported concerns that the solutions pushed by AIM for Climate “are not the kinds of technology that will benefit small-scale farmers in Africa”.
‘Big ag’ in Baku
COP LOBBYING: Hundreds of “lobbyists for industrial farming” attended COP29, analysis from DeSmog and the Guardian found, with more than 200 delegates from agriculture companies and trade groups at the talks. Nearly 40% travelled with delegations of countries, such as Brazil, “giving them privileged access to diplomatic negotiations”, the Guardian noted. The number of industrial agriculture attendees dropped from “record highs” of 340 at last year’s summit, the newspaper said. They represent “some of the world’s largest agribusiness companies, including the Brazilian meatpacker JBS, the animal pharmaceuticals company Elanco and the food giant PepsiCo”, the Guardian said. DeSmog and the Guardian also revealed that a “record” 1,261 business and industry delegates registered to attend last month’s COP16 biodiversity summit.
OFFSET ADVICE: The UK released new guidelines for voluntary carbon and nature markets in Baku, BusinessGreen reported. These aim to give “clearer guidelines to companies involved in the purchase, sale and development of carbon offsets and nature credits”, the outlet said. One of the guidelines advises that credits should “complement” emissions-cutting and other climate action, not replace them. These represent a “vote of confidence in a largely experimental financial product that’s intended to protect biodiversity”, Bloomberg said. (Read Carbon Brief’s Q&A on biodiversity offsets.) Meanwhile, Brazil’s Congress signed off on a bill setting rules for a national carbon market, according to Reuters.
FARMER FUNDS: New analysis released during COP29 found that 14% of global public climate finance for agriculture and land use went to activities relevant to small-scale farmers in 2021-22. This is a small portion given that these farmers produce 70-80% of the food eaten in Africa and Asia, according to advisory company Climate Focus, which completed the analysis. Covering the report, Bloomberg spoke to Esther Penunia, secretary general of the Asian Farmers Association, who said: “[Climate change is] affecting our crops, our yields and therefore our incomes.” The Associated Press spoke to Penunia and others about climate finance for small farmers. Elsewhere, a policy paper found that “regenerative farming” has “shown promising results” in Africa and India, First Post said.
Spotlight
The ups and downs of Brazil’s new climate pledge
Brazil released its new climate pledge at COP29 last week, committing to cut greenhouse gas emissions by 59-67% by 2035. Here, Carbon Brief speaks to two Brazilian experts about the implications of the new nationally determined contribution (NDC).
Dr Ane Alencar is the director of science at the Amazon Environmental Research Institute. Claudio Angelo is the coordinator of international policy at Observatório do Clima, a Brazilian network of civil-society organisations. The interviews have been edited for length and clarity.
For more on Brazil’s NDC, see Carbon Brief’s just-published article on the five key takeaways.
Carbon Brief: What is your opinion on Brazil’s new NDC?
Ane Alencar: Even with all the difficulties we have in Brazil, there is a commitment of the government to actually move forward and be more ambitious [on climate change]. I think they did that…even though I think it could be a little bit more. But I think this is an important step.
Claudio Angelo: Policy-wise, it’s a pretty good NDC…We can say that the NDC reflects a shift of gear for Brazil and that’s important. But, again, we’re talking about policies. We’re not talking about the target. And the target of the NDC is very weak. You can’t say it is 1.5-aligned…There are things Brazil is already doing, such as tackling deforestation in the Amazon…So, I would say [the] direction of travel is right, but the speed is totally wrong.
CB: How does the NDC compare to previous pledges made by the Brazilian government?
CA: If you look at what Brazil has already committed to doing – for instance, zero deforestation, the methane pledge, [which is a] 30% reduction in methane, just the sheer pace of increase of renewable energies in the energy mix…There’s a new sustainable fuels legislation that was just passed this year. If you put all those things together, Brazil could aim much higher than the current limits…We’re hoping to get an increased ambition ahead of COP30. I think there’s [a] margin for that in the NDC. We will certainly push for [the new NDC] to be the ambition floor, not the ambition ceiling.
CB: Are the NDC promises to combat deforestation strong enough?
AA: The government has done a very good job in the past to reach that important reduction of deforestation…However, we do have to deal with the fact that there are people who still can deforest legally. And what would be the incentives for these people to not deforest? The incentives that exist today seem not to be enough.
CB: Are pledges to boost “sustainable agriculture” sufficient to meet climate goals?
AA: I think the agriculture sector is one that can provide lots of contribution, by improving their practices, investing in technologies to reduce the cattle contributions and also with soil management…If the Brazilian agriculture sector really goes in the direction of sustainability, then I think it’s possible to actually fulfil the NDC targets.
News and views
G20 TALKS: At the G20 summit, Brazil’s president, Luiz Inácio Lula da Silva, presented a new “alliance” to tackle poverty and hunger, Al Jazeera reported. It added that 81 countries signed the initiative. Before the summit, Joe Biden became the first US president to visit the Amazon rainforest, the Associated Press reported. In his speech, he said that the incoming administration of president-elect Donald Trump would not be able to halt his country’s progress on clean energy, the newswire added. Meanwhile, Mexico’s president, Claudia Sheinbaum, proposed allocating 1% of military expenditure to fund a global reforestation programme, which could free up $24bn annually to support 6m farmers to plant 15m hectares of trees.
‘GROUNDBREAKING’ DISCOVERY: The world’s largest coral, measuring more than 34 metres wide and 32 metres long, was discovered by a team of scientists in the Solomon Islands, Pasifika Environews reported. The outlet dubbed the discovery “groundbreaking” and noted that the coral structure is between 300 and 500 years old. It quoted Enric Sala, executive director of National Geographic’s Pristine Seas project, who stressed the urgency “for rich countries to invest significantly in reducing carbon emissions to combat threats like ocean warming and acidification” as negotiations at COP29 continue. Elsewhere, a “graveyard of corals” was found off an island on the Great Barrier Reef after months of extreme weather, the Guardian said.
AIRBORNE TOXIC EVENT: Air pollution in Delhi “hit 50 times the safe limit” this week, due in part to “farmers burn]ing] crop residue in agricultural areas”, according to the Associated Press. In response, the government has started enacting strict control measures, including banning most trucks from entering the city and moving school classes online. According to the Times of India, more than 1,250 agricultural fires were recorded in the state of Punjab on Monday, “the highest single-day tally of the season”. Delhi’s environment minister, Gopal Rai, said “the time has come for artificial rain to remove this smog cover and provide relief to the people”.
FARMER FURY: Thousands of farmers “descended” on Westminster in London to “protest a tax hike they say will deal a ‘hammer blow’ to struggling family farms”, the Associated Press reported. The UK government recently announced plans to get rid of a tax break that would introduce a 20% inheritance tax for farms worth more than £1m from 2026. (BBC News factchecked how many farms this might affect.) “Everyone’s mad” at this change, the co-organiser of the protest, Olly Harrison, told AP, adding that many “want to take to the streets and block roads and go full French”. (Farmers held a so-called “siege of Paris” earlier this year amid widespread EU farmer protests.) In ongoing farmer protests across the Channel, French farmers and their tractors blocked roads around the country to protest a trade deal between the EU and Mercosur countries in South America, according to Le Monde.
PUSHBACK: European lawmakers voted to “water down” and delay the EU’s anti-deforestation law, Reuters reported. The European Commission recently proposed a one-year delay for the law, which was due to take effect this December. This delay was backed by the European parliament in a 14 November vote, the newswire said, adding that politicians also voted to “add a new ‘no risk’ category of countries with far lighter controls”. This would “severely weaken” the law, BirdLife said in a statement, “making it inadequate to address global deforestation”. Elsewhere, BBC News said that Denmark signed off on the finer details of its world-first tax on farming emissions. (See Carbon Brief’s Q&A on the Danish plan.)
HIDDEN COSTS: Agrifood systems contain “hidden costs” – such as unaccounted for impacts on health and the environment – totalling around $12tn annually, the latest State of Food and Agriculture report from the UN Food and Agriculture Organization found. More than 70% of the costs stem from unhealthy dietary patterns and are linked to non-communicable diseases, such as heart disease and diabetes. The hidden environmental costs outlined in the report included emissions of greenhouse gases, nitrogen run-off and water pollution.

GO FISH: Scientists thought the Mekong giant salmon carp was extinct. But one scientist kept looking – and recently published evidence of its survival, the New York Times reported.
New science
- New research in Ecological Economics found that climate change-induced migration of Nigerian herders seeking new grazing sites is a “key driver” of conflict between the herders and farmers. However, the study added, respondents who understood climate as the driving factor behind the migration were more likely to support policies that integrated herders into their community.
- In the 2019-20 Australian “megafires”, plants and animals were worst affected in areas that were frequently burned or had recently burned in the past, according to a new Nature study. The “unprecedented” fires had a small, but overall negative impact on the abundance and occurrence of species, the researchers found.
- Reduced deforestation brings health benefits to Amazon populations, according to new research in Communications Earth and Environment. The study found that reduced deforestation pressure lowers the incidence of forest fires, lowering particulate matter concentrations and decreasing respiratory health problems for local communities.

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.

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.

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.
