This week

EU delay

NO NDC: The EU has “failed to agree” on a 2035 target for cutting greenhouse gas emissions in time for a climate event taking place alongside the UN general assembly next week, the Financial Times reported. On 24 September, representatives from more than 100 nations will take part in an event where they will announce or offer more details on their 2035 climate plans, known as “nationally determined contributions” (NDCs), Carbon Brief understands. The FT added that, instead of agreeing to a target, EU member states have signed up to a “statement of intent”, which noted that the bloc would aim to cut emissions somewhere in the range of 66.3% and 72.5% by 2035.

DEADLY: Meanwhile, recent analysis showed that more than 16,000 heat deaths that occurred from June to August this year in the EU can be attributed to fossil-fueled global warming, reported the Guardian. Other recent research covered by Euronews indicated that this summer’s extreme weather events will cost the region about €126bn by 2029.

Australia delivers

NEW TARGET: Australia announced an NDC target of cutting emissions to between 62% and 70% below 2005 levels by 2035, reported the Sydney Morning Herald. This is a jump from the current goal of 43% by 2030, providing a “major challenge to the government and the economy”, given that Australia’s emissions have fallen by just 28% over the past two decades, the newspaper added.

RISING THREATS: The country also published its first national climate risk assessment this week, which concluded that 1.5 million Australians living in coastal areas could be at risk from sea level rise by 2050, BBC News reported. The Guardian added that the report looks at 10 “priority hazards”, including flooding and extreme heat, forecasting a rise of 190% in annual heat-related deaths in Sydney if warming reaches 2C.

Around the world

  • FURTHER CHALLENGE: Construction workers announced an indefinite strike in Belém, the Brazilian city hosting COP30 this year, to demand better wages, Folha de São Paulo reported. Reuters reported that the UN had “urge[d] its staff to limit attendance” at COP30, due to concerns over high accommodation costs.
  • CUTTING EMISSIONS: India’s power sector CO2 emissions fell by 1% year-on-year in the first half of 2025, only the second such reduction in 50 years, according to new Carbon Brief analysis. The Times of India, Hindustan Times, Reuters and the Indian Express were among those to cover the analysis. 
  • NEW THREAT: A US Environmental Protection Agency proposal to stop collecting industrial emissions data threatens plans to capture and store CO2, reported the New York Times. Meanwhile, the US National Academies responded to the Trump administration’s misleading claims, with a report calling climate change “beyond scientific dispute”, said Politico
  • ‘REALITY CHECK’: A German government report called for cost efficiency and rapid – but limited – expansion of renewables, Clean Energy Wire reported.
  • SECOND CALL: The International Energy Agency reiterated that the world would not need to invest in new oil and gas projects if demand for the fuels fell in line with the 1.5C limit on global warming, Carbon Brief reported.

The seventh assessment cycle of the Intergovernmental Panel on Climate Change (IPCC), the world’s leading climate science authority, will include more authors from global south institutions than ever before, according to Carbon Brief analysis. A total of 660 scientists from 90 countries will write the three reports in the next assessment cycle, scheduled for publication in 2029. Some 42% of those authors belong to institutions based in the global south (see chart above), according to Carbon Brief.

Tracing beef in the Brazilian Amazon

In this spotlight, Carbon Brief reports from the Amazonian state of Pará, Brazil, which is implementing new measures to track the impact of beef on deforestation.

The state will host the COP30 climate summit in November.

The Amazonian state of Pará is home to 26m beef cows. The second-largest driver of deforestation in the state is cattle ranching.

Maria Gorete Rios is a small cattle producer in Pará’s municipality of Novo Repartimento. She was the first in Pará to implement individual identification of her cattle.

Of the 78 hectares of her land, 50 hectares are used for cattle and grazing, 10 hectares for her forest reserve and four hectares for producing cocoa and other crops such as cassava, beans, squash and açaí – a fruit native to the Amazon.

Gorete began identifying her cattle thanks to Pará’s first mandatory cattle traceability programme, announced by the state government at COP28 in 2023. The programme seeks to make the cattle supply chain more transparent and to channel incentives for producers to reduce deforestation.

To track her cows, Gorete has given each of them an ear tag tracker, which allows the programme to record which farm each cow was raised on, which slaughterhouse it went to and whether it was raised in illegally deforested areas, Rodrigo Freire, private areas leader for The Nature Conservancy (TNC) in Brazil’s Amazon, explained to Carbon Brief.

To verify that an area was not deforested for cattle production, Brazil’s government has a mandatory registry for rural farmers, which collects information on land use changes over farms, Fábio Medeiros, strategic cattle partnerships director at TNC, told Carbon Brief.

Gorete supports the traceability system because she believes that rural or small producers do not keep proper records of their property. She added:

“With traceability, they will be able to keep track. I think it’s fantastic.”

Further benefits

In addition to traceability, Gorete has begun to combine livestock farming with tree planting, under an “agroforestry” system.

She said that her land had been 100% degraded by industrial livestock farming, but now her planted trees provide shade for her livestock, as well as water availability and habitat for other animals.

Gorete told journalists visiting her farm that diversifying her agricultural production with trees and beekeeping provides her with more income. She added:

“I’m happy where I am. Livestock allows me to pay the highest fees, because livestock is what sustains us. I have açaí, I have cocoa, the basis of my diet. I also have to cultivate the land.”

Medeiros said that, with COP30 coming to the state in November, more incentives are expected for producers to comply with cattle traceability in the region.

Travel to Pará was organised by The Nature Conservancy Brazil, Instituto Clima e Sociedade (iCS) and Nature4Climate.

10 YEARS OF PARIS: Ahead of the 10-year anniversary of the Paris Agreement, climate writer David Wallace-Wells reflected on progress and setbacks for climate action in the New York Times magazine.

COP REFORM: For the Chatham House blog, climate geopolitics expert Bernice Lee addressed the arguments for how the UN climate process should “evolve to move from pledge-making to delivery”.

‘BLACK GOLD’: A Reuters video showed how New York is turning food scraps into nutrient-rich soil, dubbed “black gold”.

Key developments

Huang reported to lawmakers on climate action

NPCSC REPORT: Huang Runqiu, head of the Ministry of Ecology and Environment, told Chinese lawmakers that managing the country’s carbon dioxide (CO2) intensity has become “more challenging” due to the effects of the Covid-19 pandemic, extreme weather and growing trade tensions, Bloomberg reported. According to the full text of Huang’s remarks, made during a report to the National People’s Congress (NPC) Standing Committee, the minister remarked that China’s progress on meeting the target is “broadly in line” with its current international climate pledge for 2030. [Its CO2 intensity target for 2025 is likely to be missed.] He added that challenges have worsened around balancing climate action with economic development, managing “overall and local interests” and “aligning short-term with medium-to-long-term goals”.

TARGETS ‘SURPASSED’: Huang also highlighted the progress China had made in other areas, having “already surpassed” targets for wind and solar power capacity additions and new forest stock volume, the state-run newspaper China Daily said. According to current affairs outlet China News, Huang also noted that China has continued its “efforts to enhance the clean and efficient utilisation of fossil fuels”, including “reforms” for coal-fired power plants and “steadily increasing” gas production and utilisation.

GLOBAL INFLUENCE: China is “making important contributions to the implementation of the Paris Agreement”, Huang also said, according to the full text of his remarks, having “driven substantial reductions in the costs of wind and solar power” and “advanced international cooperation on climate change”, such as in south-south collaboration. He noted that in the face of “uncertainties”, such as the US withdrawal from the Paris Agreement and the expansion of the EU’s carbon border adjustment mechanism, China will enhance its “influence, guidance and shaping power in global climate governance”.

Movements ahead of UNGA

COP30 SIGNALS: Former climate envoy Xie Zhenhua travelled with Huang to Brussels to meet EU climate lead Teresa Ribera on 16 September, Reuters reported, in order to restart “climate negotiations” ahead of the UN general assembly and COP30. It added that current climate envoy Liu Zhenmin was not expected to be present. (A photo posted on Bluesky confirmed Xie’s presence in the city.) A few days earlier, COP30 executive director Ana Toni met Huang in Beijing, where he told her that China will support Brazil in hosting a COP that “sends a strong signal” about the importance of the Paris Agreement, climate news outlet Tanpaifang reported. Toni told reporters that Brazil expects a “huge Chinese delegation” at COP, the Global Times said. She also spoke at an event at Tsinghua University attended by Xie and followed online by Carbon Brief.

UK-CHINA: Meanwhile, the UK and China established a new industrial decarbonisation working group, according to a UK government statement, focusing on areas including carbon capture, utilisation and storage. Daniel Brooker, the head of the China office at UK Research and Innovation, told finance news outlet Yicai that climate cooperation with China is “one of our immediate priorities”.

INTERCONNECTED WORLD: Separately, vice-president Han Zheng used a conference speech to urge other countries to cooperate on developing “renewable energy generation, grid interconnectivity and smart energy systems” as a way of advancing the global energy transition, according to the Communist party-affiliated newspaper People’s Daily.

First auction under new renewable pricing system

LOWER PRICES: Shandong province held the country’s first renewable power auction, following the launch of new rules for the pricing of wind and solar power, industry news outlet BJX News reported, with the auction price of wind power set at 0.319 yuan per kilowatt-hour (yuan/kWh) and those for solar set at 0.225 yuan/kWh. The low prices set by the “bellwether” province signalled that “renewables prices [across China] in the future will be lower than under the previous system”, Reuters said, adding that it could “discourage” further investment. On LinkedIn, David Fishman, principal at the Lantau Group, said that while the wind power prices would likely be acceptable for developers, the solar prices would be “very tough”, citing one as saying they would likely “abandon” all future projects in the province.

PLANS ‘PROMPT’: Meanwhile, the National Energy Administration (NEA) urged local governments during a video conference to “promptly” release their plans for implementing the pricing reforms, energy news outlet International Energy Net said, to “stabilise” industry expectations. Separately, the NEA revealed during the conference that, between January and July 2025, China’s installed renewable energy capacity grew by 283 gigawatts (GW) to 2,171GW, current affairs outlet China News reported. In August, BJX News said, thermal-power generation grew by 1.7% – slower than July’s growth rate – while wind power grew by just over 20%, solar grew by 16% and hydropower fell by 10%.

LOCALISED PROJECTS: The NEA also co-released a notice on “improving pricing mechanisms” for localised new-energy projects, International Energy Net reported, referring to projects that “both generate and consume electricity” such as zero-carbon industrial parks. The notice outlined benchmarks for how much of their own renewable energy such projects should sell and consume, clarifying that such projects should “bear transmission and distribution fees, system operation costs and other expenses”, it added.

China set targets for new AI energy projects

AI PILOTS: China plans to increase the use of AI in the country’s energy sector, state news agency Xinhua reported, in order to “enhance energy security, improve operational efficiency and support the country’s green and low-carbon transition”. China will “promote the deep application of at least five specialised large models”, which could be used in the power grid, power generation, coal, oil, gas or other areas, according to industry news outlet China Energy News. It also reported that China plans to identify ten or more “replicable, scalable and competitive” pilot projects. Consulting firm Trivium China wrote in a note that the plan “positions AI as an indispensable tool” on climate change.

DOUBLING STORAGE: China aims to “almost double” new-energy storage capacity by 2027 to 180GW, according to a new industry plan, Reuters reported. Lithium-ion battery storage is likely to comprise the bulk of new additions, economic news outlet Jiemian said. Meanwhile, according to a new government action plan for 2025-2026, new-energy power equipment companies are expected to achieve “steady” annual revenue increase, while traditional power equipment firms should aim to grow “approximately 6%” and “leading” companies by 10%, Xinhua said.

POLICY WATCH: China adopted the atomic energy law, its first foundational law for the nuclear sector, Jiemian reported. China’s environmental code – also the first of its kind – remains under discussion, according to China News. Elsewhere, the country updated its plan to “advance the three-north shelterbelt forest programme”, China Daily said. The National Development and Reform Commission called for “exploring” pathways for real estate investment trusts to invest in ultra-high voltage transmission projects, BJX News reported. BJX News also covered new guidance on improving electricity spot markets.

Q&A: Will China and the BRICS fill the ‘leadership gap’ on climate change?

Amid a rapidly fracturing geopolitical order, there have been growing calls for China to “step into [the] leadership gap” left by the US on climate change.

One platform that it could use to do so is BRICS, an increasingly influential and assertive group that includes COP30 host Brazil.

In this issue, Carbon Brief explores whether or not China, alongside the BRICS, could become climate leaders. The full article is available on Carbon Brief’s website.

The BRICS group represents a number of emerging economies that aim to “increas[e] the influence of global south countries in international governance”.

Active full members include founding members Brazil, Russia, India and China, as well as South Africa, Egypt, the United Arab Emirates, Ethiopia, Indonesia and Iran.

Together, they represent 27% of global gross domestic product, 49% of the world’s population and 52% of carbon dioxide emissions, according to Carbon Brief calculations.

Four of the members – Brazil, China, India and South Africa – also form the BASIC bloc, a group with a significant voice at UN climate summits and other negotiations.

How do the BRICS approach climate change?

Lucas Carlos Lima, professor of international law at the Federal University of Minas Gerais in Brazil, wrote that recent joint statements show the BRICS had “placed climate change squarely at the centre of the bloc’s agenda”.

In July, the BRICS summit resulted in a joint declaration demanding that “accessible, timely and affordable climate finance” is provided to developing countries.

The statement also highlighted the nations’ “resolve to remain united in the pursuit of the purpose and goals of the Paris Agreement”.

However, the BRICS leaders’ declaration also “acknowledge[s] fossil fuels will still play an important role in the world’s energy mix”.

The inclusion of this language “undermin[es] the positives” of the bloc’s other statements on climate action, according to a response from Jacobo Ocharan, head of political strategies at Climate Action Network International.

What is the role of fossil fuels in the BRICS?

Many BRICS nations remain heavily reliant on fossil fuels, both for electricity generation and to support their wider energy systems.

However, this picture is starting to shift, with almost all BRICS members having adopted net-zero targets ranging from 2050 to 2070.

More tangibly, the addition of new clean-power projects means that fossil-fueled electricity generating capacity now makes up less than half of the installed total in the BRICS group as a whole in 2024, as shown in the figure below.

BRICS_capacity-targets

Right: The year by which BRICS countries have pledged to reach net-zero. Source: Global Energy Monitor, Climate Action Tracker.

Non-fossil power, driven by “unprecedented” renewable energy growth in China, India and Brazil, accounted for 53% of the installed electricity generating capacity in BRICS countries in 2024, according to thinktank Global Energy Monitor (GEM).

Continued BRICS focus on clean energy makes it “unlikely that fossil capacity will overtake non-fossil again”, James Norman, research analyst at GEM, told Carbon Brief.

Several BRICS members, including Russia, the UAE, Iran and Indonesia, are nevertheless leading producers and exporters of fossil fuels.

China and India, meanwhile, are by some distance the world’s largest and second-largest coal users, respectively.

Nevertheless, in the short term, this might not affect the BRICS group’s climate ambition overall.

Russia does not seem to be “blocking” the “solid outcomes” of recent BRICS climate negotiations, said Kate Logan, director of the China climate hub and climate diplomacy at the Asia Society Policy Institute (ASPI).

Will China and the BRICS emerge as climate leaders?

With the withdrawal of the US from the Paris Agreement under the Trump administration, there have been increasing calls for China to take up the mantle of climate leadership.

China, at least publicly, is eschewing these calls, but does seem to be open to agreeing to “demonstrate leadership” in tandem with others, as seen in an EU-China joint statement on climate change published in late July.

Many are watching for signs of whether China’s upcoming international climate pledge, which may be published next week, will contain ambitious targets that will encourage greater global ambition.

Beatriz Mattos, research coordinator at Brazil-based climate-research institute Plataforma CIPÓ, tells Carbon Brief that China’s position as a “major investor in the renewable energy sector” means there is “enormous potential” for both it and the BRICS to assume a climate leadership role.

New science 

Carbon emissions from forest harvest and fire offset approximately half of carbon sequestration of forestation in China during 1986-2020

Agricultural and Forest Meteorology

A new study examined the combined role of “forest activities and fire disturbance” (FAFD) on the effectiveness of China’s carbon sinks. It estimated that, between 1986 and 2020, the carbon emissions resulting from harvesting forests and forest fires offset around 54% of the carbon sequestration occurring through forestation. These findings, the authors said, “highlight the importance of accounting for carbon emissions from deforestation and forest fire when aiming to maximise carbon sequestration through forestation”.

Temperature extremes in early life and human capital: evidence from China’s labour market

Climatic Change

“Early-life exposure” to both extreme heat and extreme cold has “significant and persistent negative effects on adult labour income”, new research has found. The study, which draws from a dataset of more than one million individuals from China, said that, under a scenario with moderate warming (SSP2-4.5), average labour-income loss across China could total 0.77%, with the provinces of Qinghai, Henan, Fujian and Gansu most severely affected. It added that the impact of extreme heat on foetuses is “particularly pronounced”, with significant implications for future earnings.

Growing trees for shade has ‘enormous’ potential for cutting cocoa emissions

Published

on

Growing tall trees to provide shade for cocoa plantations in west Africa could sequester millions of tonnes of carbon, according to a new study.

The research, published in Nature Sustainability, finds that the additional carbon stored in shade trees, such as banana and palm trees, could entirely “offset” cocoa-related emissions in Ghana and Ivory Coast, without reducing production.

West Africa produces about 60% of the world’s cocoa, which is one of the most emissions-intensive crops to grow.

The authors map the shade provided by trees across cocoa agricultural systems in west Africa, then project how much additional carbon storage would be created by expanding it.

An author of the study tells Carbon Brief that cocoa plantations have been a “big” driver of deforestation and the emissions it causes, but the findings show that there is “huge potential” for cocoa to be “part of the solution”.

Cocoa plantations

Cocoa trees thrive in rainforests, as they need abundant rain, high humidity and stable temperatures. They often grow under the shadow of other plants, such as bananas, plantains and palm trees.

Two countries in west Africa – Ivory Coast and Ghana – dominate global cocoa production and are major exporters to the US and Europe.

The shading on the map below shows where cocoa is grown in Ivory Coast (left) and Ghana (right).

Both countries have favourable conditions for cocoa production, including tropical forests – which provide nutrients to the soil – a great deal of rain, warm temperatures and low production costs.

Two million farmers in the region rely on cocoa farming for their livelihoods, the study says, and cocoa contributes 10-20% of the two countries’ gross domestic product.

However, cocoa has “one of the most emissions-intensive footprints of all foods”, the study adds.

A 2022 study found that producing 1kg of cacao beans in Ivory Coast releases, on average, 1.5kg of CO2-equivalent (CO2e) – largely a result of deforestation. Since 2000, cocoa plantations have driven 37% of forest loss in protected areas in Ivory Coast and 13% of the loss in protected areas in Ghana.

Cocoa plantations cover more than three-and-a-half times as much land as the remaining intact forests in west Africa, according to the study.

Dr Wilma Blaser Hart, a research fellow at the University of Queensland and an author of the study, tells Carbon Brief:

“That land-use change is what makes cocoa such a carbon-intensive product, because there has just been so much forest loss for being able to produce cocoa.”

Shade-grown cocoa crops

Agroforestry is an agricultural method that combines the planting of crops with trees. Agroforestry can raise incomes for farmers and provide ecosystem services, including soil health improvement, biodiversity conservation and carbon sequestration.

The study investigates the amount of carbon that is currently stored in cocoa plantations in Ivory Coast and Ghana, as well as the potential carbon sequestration if agroforestry were expanded in these countries.

The authors use drones and machine learning to map the cover of shade trees, finding that 13% of the combined area of Ivory Coast and Ghana is currently covered with these trees.

In the study, “shade trees” refers to any trees taller than eight metres – the maximum height of cocoa trees.

The map below shows the area of shade trees in cocoa-growing areas specifically for 2022. The colours indicate levels of tree cover from 0-15% (blue), through to 15-30% (green) and more than 30% (yellow).

The map reveals that cocoa production is “overwhelmingly dominated by full-sun monocultures and low shade-agroforestry”, the study says.

Using satellite data, global maps of tree canopy height and on-ground verification, the researchers map the amount of “aboveground biomass” held by cocoa plantations.

Aboveground biomass comprises all living vegetation that lies above the soil – trees, leaves and other plant matter.

The map below shows the amount of aboveground biomass in both countries. The areas in yellow are those with the highest biomass and, therefore, more stored carbon.

The insets on the right depict patterns of aboveground biomass in i) a cocoa monoculture in Ghana, ii) an area of cocoa agroforestry in eastern Ghana and iii) an undisturbed forest in Kakum National Park. Source: Becker et al. (2025)

The authors project that if all cocoa plantations increased their cover of shade trees to at least 30%, the additional, taller trees could sequester an “enormous” amount of carbon – 307m tonnes of CO2e (MtCO2e) – enough to fully counterbalance the current cocoa-related emissions in both countries, without reducing production.

Blaser Hart tells Carbon Brief:

“Cocoa itself is a small tree. [It] can grow up to about eight metres tall, so it also sequesters carbon. [But] we found that tall trees that are towering high above cocoa – often timber trees – sequester much more carbon than cocoa.”

In addition, she says, the cover from large trees is “much better for cocoa” since it protects them during the hottest hours of the day, while allowing light through. They also shed large amounts of “litter”, which gets incorporated as organic matter into the soil, sequestering carbon from the atmosphere.

Barriers and limitations

The authors acknowledge several limitations to their study.

For example, they say, the analysis may underestimate the proportion of shade tree cover by excluding trees shorter than eight metres. They also note that the analysis does not consider all of the features of agroforestry systems, such as which species are planted.

Kayeli Laurence is a PhD student of landscape ecology at Jean Lorougnon Guédé University in Ivory Coast and an expert in agroforestry. The researcher, who was not involved in the study, tells Carbon Brief:

“The identified limitations call for caution, particularly when it comes to local, small-scale analyses. However, they do not undermine the general trends highlighted by the study.”

Laurence notes that the study results are consistent with other research highlighting the carbon sequestration potential of agroforestry systems. She says that the projection of carbon sequestration is “ambitious, but credible”. However, she adds:

“In practice, achieving this goal will strongly depend on local conditions: availability of species, technical support, farmers’ willingness and, above all, economic incentives.”

The study also acknowledges that smallholder farmers in west Africa “face several barriers” to adopting agroforestry, including limited incentives and insecure land tenure.

The non-profit scientific research organisation Project Drawdown notes that implementing a certain category of agroforestry called “multistrata” – a combination of long-lasting crops and multiple layers of trees or vegetation – in humid tropical climates would cost more than $1,300 per hectare.

Blaser Hart tells Carbon Brief:

“That’s a huge cost. And it’s not money that farmers have available.”

International landscape

Blaser Hart says that cocoa agroforestry provides further benefits to ecosystems, besides carbon sequestration. These include cooling the air, improving soil fertility and nutrient cycling and providing habitat for wildlife. She adds:

“We’re currently doing a big study on how agroforestry can help to provide habitat for birds. There also seems to be a bit of mammals that use cocoa agroforestry systems. In Ghana, we’re finding quite a bit of genets and civets that are in these systems. From Brazil, there’s a bit of research in the Atlantic Rainforest that shows that some monkeys use them as permanent habitat and others just as corridors to move through.”

Agroforestry is included in the climate commitments of around 40% of developing countries under the Paris Agreement, according to the study.

At the corporate level, the cocoa industry has made commitments to plant “millions of shade trees in agroforests to improve the sustainability of the sector”, the study says.

Blaser Hart tells Carbon Brief that the researchers hope the work will encourage the cocoa industry to better plan its agroforestry interventions, “rather than just haphazardly handing out trees here and there”.

Laurence suggests that policymakers should improve climate finance to support farmers in transitioning to sustainable agricultural systems, while chocolate producers and certification bodies should make stronger commitments to create “real demand for sustainable cocoa produced through agroforestry”.

Ultimately, the study notes that the methods it developed to assess the status of trees in agricultural systems can be used for other commodities grown in agroforests, such as coffee.

EU ministers fail to agree climate targets, raising risk leaders will weaken them

Published

on

Environment ministers representing the European Union’s 27 member states failed to agree emissions reduction targets for 2035 and 2040 in Brussels on Thursday, instead asking their countries’ leaders to weigh in when they meet next month.

With several primarily Eastern European nations opposed – and others wavering – ministers agreed to ask their leaders to consider the key climate goals at a European Council meeting in October, in the hope of agreeing targets before the COP30 climate summit in November.

This means that the EU will not submit its 2035 target in time for it to factor into the UN’s annual synthesis report of national climate plans, due in late October, which will analyse governments’ climate commitments and estimate how far off the Paris climate agreement’s temperature targets they are.

It also means that EU officials will head to the United Nations General Assembly in New York next week without new targets to offer. Instead, they will just have what the Danish minister chairing the talks called a “statement of intent” to reduce emissions by between 66.25% and 72.5% below 1990 levels by 2035.

Some ministers that want stronger targets warned the delay could lead to the emissions cuts being watered down. A decision by environment ministers on the 2040 target can be made through qualified majority voting. But EU leaders will decide on the basis of unanimity, allowing climate laggards to block ambition. It is not clear if EU leaders will decide on the target at their next meeting or just debate it.

Ahead of today’s Environment Council meeting, the environment minister of Sweden – which supports the European Commission’s proposed target to cut emissions 90% between 1990 and 2040 – walked up to waiting journalists and said unprompted that “hesitation is a luxury that we cannot afford”.

Romina Pourmokhtari added that she was “quite disappointed at recent developments”, adding that her message to “all countries but particularly Germany and France” – which have pushed for a delay so leaders can contribute – is that “I and Sweden do not believe that it will become a better product by prolonging this process. This will not create a better outcome”.

But Elisa Giannelli, E3G lead on climate governance and European politics, was positive. She told Climate Home News that “we’ve heard enough member states being quite positive about the commission’s proposal today”, adding “it will eventually be down to France to swing over to the “supportive camp” once leaders have “provided the reassurance and guidance they are calling for”. France is widely regarded as the swing vote.

At the meeting, representatives from Czechia, Slovakia, Poland and Hungary opposed the 90% proposal. Krzysztof Bolesta, from the Polish environment ministry, said an 83% target is “at very, very high cost, maximum we can do”.

Slovakia’s environment minister Tomáš Taraba said “it would be good to start with a lower target and – if necessary and feasible – we can increase in the next revision”, a position supported by Hungary’s Anikó Raisz.

On the other side, representatives of the Netherlands, Spain, Germany, Luxembourg and Austria supported the 90% proposal. Spain’s Sara Aagesen Munoz said it was “science-based” and the Dutch representative called it “feasible” and “the most logical way towards climate neutrality in 2050”.

Missing UN deadlines

Simon Stiell, executive secretary of the UN convention on climate change, welcomed the EU’s statement of intent despite the bloc’s failure to announce a target in time for the UN systhesis report of climate plans. Stiell urged European leaders to aim for the top of the proposed range.

“If these targets are met with speed and at scale, the EU has so much to gain,” Stiell said in a statement. “It won’t just be a global leader on climate change and clean energy, the more action it takes, the more the continent stands to benefit, with stronger economic growth and thriving new industries powered by cheaper and cleaner energy.”

On his way into the meeting, the German environment ministry’s state secretary Jochen Flasbarth blamed the European Commission for the “loss of time”. “If the Commission would have provided the dossier earlier then we would be in a different situation,” he told reporters.

EU Climate Commissioner Wopke Hoekstra told the ministers that he had hoped the targets would be decided today but the delay “could also be useful to ensure the broadest possible political support”.

Asked ahead of today’s meeting what message missing the UN’s end-of-September deadline for 2035 NDCs will send, Finland’s environment minister Sari Multala said it is “hard for us to require the others – our international partners to do the same if we don’t deliver ourselves”.

According to the UN, 36 nations have already submitted their 2035 targets – known in UN jargon as nationally determined contributions (NDC). Australia today promised to cut emissions 62-70% between 2005 and 2035. China is expected to announce its target this week or next and many other nations will launch their targets at a UN summit in New York on Wednesday.

Losing climate leadership?

Asked if China will take over the EU’s climate leadership on the international stage, Hoekstra said “it would be fantastic if they would outperform our NDC”. Separately, Poland’s Bolesta told a reporter, “I don’t know why you would say we are worse than China” as “it’s not about who is faster, it’s about who is more robust and more credible.”

    Hungary’s environment minister Anikó Raisz said “those from the EU going to New York, we have nothing to hide” as the EU is a “leading example”. Hoekstra said the EU’s NDC would be among the most ambitious in the world along with “our friends from Great Britain and a couple of other places”.

    Speaking yesterday, the chair of the Alliance of Small Island States negotiating group, Ilana Seid from Palau, said she was “putting pressure” on the EU to “step up” because “their NDC announcement would really change the momentum and the kind of ambition heading into the COP”.

    The timeline for deciding the two official EU targets is now unclear, but is likely to involve a specially-convened European Council leaders’ meeting and then another environment ministers meeting.

    Danish environment minister Lars Aagaard said he hoped the targets would be adopted ahead of COP30 “as this would send a strong signal to the world – but ultimately we are, of course, in the hands of states and governments”.
