The three countries hosting the annual COP climate summits from 2023-2025 – known as “the Troika” – have again called on governments to submit stronger climate action plans that can keep the warming goals of the Paris Agreement “within reach”.
The United Arab Emirates, Azerbaijan and Brazil this week in New York reiterated their promise to lead by example and produce by the end of this year nationally determined contributions (NDCs) aligned with the Paris pact’s objective of limiting global warming to 1.5C above pre-industrial levels.
But they failed to announce any numbers or flesh out what a 1.5C-compatible NDC means for them. Observers keen to understand how the three nations will reconcile a science-based climate plan with their expanding fossil fuel ambitions were left disappointed.
“We witnessed a worrying case of cognitive dissonance,” said Romain Ioualalen, global policy manager with Oil Change International, which campaigns against fossil fuels. “At a time of grave climate urgency, the COP Troika is failing to deliver the leadership and clarity needed to raise climate ambition.”
The Troika has previously indicated that there is no universally accepted definition of what a 1.5°C-aligned climate plan should or should not include. “It’s up to each one to decide,” Brazil’s head of delegation, Liliam Chagas, said at the Bonn climate talks in June, raising fears of “1.5-washing”.
‘Ten tests’ for a 1.5C climate plan
That view is not shared by many climate experts and campaigners who are issuing suggestions for what such an NDC should look like.
A group of leading civil society organisations this week published an open letter that outlines “ten essential tests” to determine whether countries’ plans meet the 1.5C goal – seen as safer than the other, higher ceiling of “well below 2 degrees” set in the Paris Agreement.
The tests outlined in the letter include a commitment to end fossil fuel expansion, detailed and measurable targets both for the whole economy and for specific sectors such as transport, building and agriculture, provisions for wealthier countries to scale up climate finance, and measures to protect natural ecosystems and make food systems greener.
UN climate chief warns of “two-speed” global energy transition
“A lot of the failure or success of [the] Paris [Agreement] is going to be determined in the next eight or nine months as countries put forward their next round of NDCs,” said Alden Meyer, a senior associate at E3G and veteran watcher of the UN climate process. “If these don’t step up and meet the mark, it’s really our last chance… this is a critical moment.”
To limit average temperature rise below 1.5C, scientists with the Intergovernmental Panel on Climate Change say global emissions need to peak before 2025, shrink 60% by 2035 from their 2019 level, and continue on a steep downward trajectory, reaching net-zero emissions of carbon dioxide by around mid-century.
Fossil fuels in the spotlight
The next round of updated NDCs, due by next February, should turn the goals agreed at COP28 last year into practice, advocates say. In the energy sector, that means laying out plans to triple renewable energy capacity and double the rate of improvement in energy efficiency by 2030 – and, crucially, transition away from fossil fuels.
Climate experts and campaigners have stressed that a 1.5C-aligned NDC needs to include an explicit commitment to no new coal, oil and gas exploration, as well as credible targets for slashing existing production and eliminating fossil fuel subsidies.
“Claiming to lead on climate while continuing the expansion of oil, gas and coal production is indefensible at this point,” said Natalie Jones, policy advisor at the International Institute for Sustainable Development. “Governments need a plan for reducing reliance on fossil fuel production,” she added.

Fossil-fuel reduction targets will be closely watched as a litmus test for the ambition of major hydrocarbon producers, including the Troika of COP presidencies. The UAE, Azerbaijan and Brazil are set to increase their combined oil and gas production by 33% by 2035, according to a new analysis by Oil Change International.
Brazilian President Luiz Inácio Lula da Silva aims to turn his country into the world’s fourth largest petrostate (it now ranks ninth), opening new extraction frontiers both on land and offshore, including in the Amazon. This plan contrasts with Brazil’s promise to present a new NDC aligned with the 1.5C temperature goal this year – reaffirmed by Lula himself in his speech at the UN General Assembly this week.

“As long as the Brazilian government insists on extracting oil and gas, especially in the Amazon, talking about decarbonising the economy and a fair energy transition is a pure exercise in rhetoric,” said Ilan Zugman, Latin America managing director for campaign group 350.org.
Azerbaijan has similarly come under renewed criticism this week with researchers at Climate Action Tracker (CAT) slamming its existing climate goals as “critically insufficient”.
The scientific watchdog said Azerbaijan was among “a tiny group” of countries that had weakened the targets in its latest NDC, published in late 2023, contradicting the Paris Agreement’s requirement that each climate action blueprint should be more ambitious than its predecessor. CAT singled out the Caspian country’s plans to expand fossil fuel production by 30% over the coming decade and its rising methane emissions.
Azerbaijan is now working on a new NDC that should be in line with the 1.5C temperature goal of the Paris Agreement, the government said.
Looking beyond energy
But, while energy is a crucial piece of the puzzle, it is not the only economic sector that needs a dramatic transformation in order to limit global warming to 1.5C. Agriculture, food production, industry and transport all contribute a large share of greenhouse gas emissions.
Experts say that spelling out specific emissions reduction targets for each sector can help guide policy-making across different government departments and attract larger investments.

E3G’s Meyer told journalists that “a robust consultation and transparent engagement process” are also key to building a 1.5C-aligned NDC. “If you’re going to get buy-in to implementation of the NDCs on the ground – which is the real key to reducing emissions – you need all those sectors engaged and backing the plan,” he added.
Mike Hemsley, deputy director at the Energy Transitions Commission think-tank, told Climate Home that sectoral targets will also play a pivotal role in engaging the private sector, alongside roadmaps and policy packages to implement them. “There’s increasing recognition that if you don’t have that in there, you’re not going to actually realise the ambition you set out in the NDCs,” he said.
‘Creative accounting’ trap
With goals only as good as the measures taken to meet them, a significant gap remains between the already-deficient set of national climate targets on paper and action in the real world.
Civil society groups say that governments need to outline how they are planning to hit their NDC targets in a clear and transparent way without resorting to “creative accounting”, as CAT warns.
A major sticking point is the reliance on forests and other carbon sinks to bring down emissions, because of the complex calculations involved and the unpredictable risk of carbon being released back into the atmosphere if, for instance, trees are decimated by a forest fire.
Australia, for example, has been accused by CAT of creating an “illusion of progress” towards its NDC targets by constantly revising its carbon sink assessment upwards and allowing more room for increased fossil fuel emissions.
E3G’s Meyer is sceptical that, despite the promises of 1.5C -aligned NDCs, countries will step up with the level of ambition needed – and said the task for COP30 host Brazil next year should be to encourage countries to work out how to fill the gaps.
“We need to see [the next NDCs] as a floor not a ceiling, and say what more can we do to supercharge ambition,” he said.

As COP Troika dithers on 1.5C-aligned climate plans, experts set the bar high
Aviation is on track to be responsible for 80% of the UK’s carbon dioxide (CO2) emissions by 2050, according to the Climate Change Committee (CCC).
Emissions from flying have more than doubled since 1990 – driven by rising passenger numbers – even as the climate impact of every other sector in the UK economy has fallen.
The UK does not have “credible” policies in place to reverse this trend of rising emissions, says the CCC in new advice to the government on future aviation policy.
The government has signalled its support for expanding Heathrow, the nation’s largest airport, while relying on “techno-fixes” such as “sustainable aviation fuels” (SAFs) to cut emissions.
Yet, even without Heathrow expansion, the CCC says aviation emissions are on track to be higher in 2050 than they are today – reaching 38m tonnes of CO2 (MtCO2).
As the chart below shows, this would account for most of the remaining CO2 from the UK economy, all of which would need to be removed from the atmosphere in order to meet the legal target of net-zero emissions.
Expanding Heathrow would add another 2.4MtCO2 in 2050, amounting to around 5% of all the UK’s emissions. (This would increase to 4.5MtCO2 when expansion is complete in 2054.)
With a final decision on Heathrow expansion expected by 2029, the government asked the CCC for its advice on whether the plan is compatible with the UK’s climate targets.
The CCC has concluded that the UK simply lacks sufficient policies to reduce aviation emissions and “expanding Heathrow would compound the problem”. In a press briefing, CCC chair Nigel Topping told journalists:
“The UK does not currently have a credible plan to reduce [aviation emissions] in line with net-zero, so that creates a serious challenge for meeting our climate commitments.”
The “jet-zero strategy”, launched by the previous Conservative government in 2022, set out plans to cut aviation emissions. However, the Labour government has since accepted that the strategy’s expectations for SAFs, electric planes and fuel-efficiency improvements were unrealistic.
The CCC says a “credible and robust net-zero policy framework for aviation” should be set out in a revised strategy, which is planned for 2027. Only then could Heathrow expansion be aligned with the net-zero goal, adds the committee.
As part of this new strategy, the CCC says the “aviation sector needs to take responsibility for its emissions”. It says policies should be designed based on the “polluter pays” principle, requiring the aviation industry to fund its own SAFs and CO2 removal.
Specifically, the committee says funding will be needed for “engineered removal” technologies, such as direct air carbon capture and storage (DACCS).
These technologies are currently “not yet available at the scale required”, but are vital for the kind of permanent CO2 removal needed to mop up aviation emissions, says the CCC.
(“Natural solutions” such as tree planting are the other main way CO2 is expected to be removed from the atmosphere. However, the CCC envisages these removals offsetting the remaining methane emissions from livestock agriculture in the UK, whereas it says “engineered removals” would be required to remove and store CO2 from flights.)
The CCC acknowledges that placing decarbonisation costs on airlines would likely lead to higher ticket prices. It estimates that this could mean an increase, in 2024 prices, of around £150 for a return trip to Alicante, Spain, and £400 for a return trip to New York by 2050.
However, it says this is preferable to a public spending approach, which would result in the roughly 50% of the population who do not fly paying for flight-related CO2 removals.
In addition, the committee notes that higher costs would help to manage demand for flights, which would otherwise be expected to increase considerably over the coming decades.

A fifth of the world’s greenhouse gas emissions are linked to international trade in goods and services, a new tracker shows, spotlighting a little-studied issue that researchers say should be tackled by the UN climate process.
Currently, as part of the Paris Agreement, every country is responsible for counting and reducing the planet-heating emissions that are produced within its territory. Manufacturing countries, for example, may have high emissions even if what they make is exported for consumption elsewhere.
But new analysis from the European Climate Foundation (ECF) and climate consultancy Matière, based on the tracker’s data, shows that some countries have a high footprint of “imported emissions” from goods and services they ship in. These emissions are often ignored in the places where the products are consumed because they are not formally counted under greenhouse gas inventories.
In the European Union, for example, while domestic emissions have declined since 2015, imported emissions have remained unchanged, the analysis shows. In some countries, like Austria or Sweden, they are as high as the country’s entire annual carbon footprint.

As science comes under attack at UN talks, climate movement splits over how to respond
A rift over how IPCC messages are produced and turned into policy is creating tensions in the world’s most influential coalition of climate NGOs
Former EU lead climate negotiator Jacob Werksman said that under the Paris Agreement, these traded emissions are accounted for in the countries where they are originally produced, but importing countries can also take responsibility for their consumption.
“It starts with a wide recognition by many jurisdictions around the world that we need to know the carbon content of these products, and we then need to agree what is a fair, effective, transparent and relatively easy-to-implement way of measuring that carbon in traded products,” he told a launch event for the trade emissions tracker, which contains data for different countries, sectors and gases.
Trade and its role in addressing climate change has become a higher priority at UN climate talks after a push led by emerging economies including China, India and South Africa led to the first trade and climate change dialogue held this year at the mid-year session in Bonn.
At the upcoming COP31 UN summit in Antalya, some voluntary initiatives like the Brazil-led Integrated Forum on Climate Change and Trade are expected to continue, but the issue does not feature in Türkiye’s Action Agenda of climate initiatives and formal negotiations are not scheduled on the topic.
China: the world’s top emissions exporter
As a manufacturing powerhouse, China ranks first in the new tracker as the world’s top-emitting country, but the data shows that a large chunk of the country’s carbon emissions – an amount larger than Brazil’s entire annual carbon footprint – are linked to products that are exported and consumed abroad.
Russia, Brazil, the US and the EU rank as the top destinations for Chinese trade-related emissions, which are mostly linked to components for power generation, basic metals like copper and lead, and non-metallic minerals like graphite and phosphorus.
Yet China is also the world’s top emissions importer, related mostly to agricultural products, fossil fuels and minerals brought from the US, the EU, Japan and India, among others. The US ranks second by a close margin, with both countries importing about 1.6 billion tonnes of CO2 equivalent.
China’s industrial engine starts to break its fossil fuel habit
Richard Baron, ECF’s industrial policy and trade director, said Chinese clean energy products are key for reducing emissions around the world, adding that Europe is “not able to do without those technologies” for its energy transition.
“China has an emissions trading system that counts CO2 differently there. But if China and the EU were to agree on some kind of translation mechanism to say ‘this is how we measure it’, and companies can understand the protocol to navigate both markets, that would set the tone for a lot of other conversations,” he said at the platform’s launch event last week.
The analysis suggests that if the EU and China aligned their climate requirements for products, the resulting standards could influence trade flows representing about 7% of global emissions.
Baron said there’s “a plethora” of multilateral spaces to hold these discussions, including the climate and trade dialogue at the UN climate talks or the Climate Club at the Organisation for Economic Co-operation and Development (OECD), which seeks to cut industrial emissions.
Trade breaks into agenda of UN climate talks – but will it have teeth?
Controversial trade measures
Instruments like the Europe’s Carbon Border Adjustment Mechanism (CBAM) – a recent piece of legislation that penalises emissions-heavy imported products – are one tool that could be used to address trade-related emissions, said Antoine Oger, executive director at the Institute for European Environmental Policy.
He said a significant portion of imported emissions in Europe are already covered by CBAM, as it includes sectors like cement, iron and steel, fertilisers and aluminium. This then allows the EU “to engage in constructive dialogue with our trade partners”, he added.
But across diplomatic summits, including at UN climate talks, emerging economies have pushed back heavily against the CBAM and other trade measures. The most recent BRICS declaration adopted on Saturday by 11 such countries – including China, India and Russia – condemns “protectionism under the guise of environmental objectives”.
The declaration calls for the “elimination of such unlawful measures”, which they argue have “far-reaching negative implications for the human rights, including the rights to development, health and food security” of vulnerable communities.
“The question of responsibility is a political question,” Oger said. “These emissions exist – they are emitted somewhere to make a product that will be consumed elsewhere. So you can debate responsibility but the idea is for the two parts to recognise there’s a problem.”
The aim, he added “is not to point fingers, but to accept this is a reality of our emissions profiles and ask what we can do about it”.

International trade linked to 20% of global emissions – but imports ignored
All the ambulance services in England experienced some of their busiest-ever days during this summer’s record-breaking June heatwave, according to data obtained by Carbon Brief.
In June, temperatures climbed past 37C in parts of the country as authorities declared only the second ever “red” extreme heat warning.
Four out of 10 NHS ambulance services, including London’s, responded to unprecedented numbers of life-threatening emergencies on at least one day from 23-27 June.
Another two services – in the south-west and east of the country – received their highest volume of 999 calls on record.
Ambulance services provided data on their busiest days since records began, in response to freedom-of-information (FOI) requests from Carbon Brief.
The results show how demand during the June heatwave exceeded levels seen during the traditionally busy winter season in other years – and even the height of the Covid-19 pandemic – for many services.
Heat demand
Extreme heat ramps up the risk of numerous life-threatening conditions, including heart disease and respiratory problems.
England experienced record-breaking temperatures at the end of June, with the whole country covered by amber or red “heat health alerts” from the government.
A red alert, which was issued for the entire Midlands and south of England, indicates “significant risk to life for even the healthy population”. This was only the second time such an alert has been triggered.
Researchers calculated that there were nearly 3,000 heat-related deaths in the UK this summer. There has also been unprecedented demand for A&E departments and some ambulance services.
To investigate the strain facing ambulances, Carbon Brief sent FOI requests to the 10 NHS ambulance trusts in England, asking for lists of their busiest days.
This covered both the total volume of 999 calls and “category 1” responses – referring to incidents involving “life-threatening injuries and illnesses”, such as heart attacks.
The chart below shows the busiest days on record for England’s ambulances, including both total calls and category 1 responses. Most services were able to provide records back to the 2010s. (See: Methodology.)
The five-day period from 23-27 June is overrepresented in these results, with at least two heatwave days ranking in the top 20 for every service in the country.
This trend is especially pronounced in the south and east of England, where June temperatures exceeded 36C and even approached 38C in some regions.
London, South East Coast, South Central and North East ambulance services all reported daily records for responding to life-threatening emergencies during the heatwave.
For the South East Coast and South Central services – which cover a region stretching from Oxfordshire to Kent – 25, 26 and 27 June all saw unprecedented numbers of category 1 callouts.
South Western and East of England services both saw record numbers of 999 calls on 26 June, the same day the highest-ever June UK temperature was reported in Norfolk.
It is worth noting that demand for ambulance services – including category 1 calls – has been growing for many years, driven by factors such as an ageing population, more complex health conditions and growing mental-health pressures.
This helps to explain why dates from before the 2020s are rare in the top rankings provided to Carbon Brief.
Beyond the heatwave, 2026 as a whole is on track to be a record year for ambulance demand.
‘Stifling heat’
On 26 June, the busiest day of the heatwave, ambulances across England responded to 4,084 life-threatening emergencies.
The average daily volume of such incidents is normally around 2,500 during the summer months.
Stu Holliday, head of emergency preparedness, resilience and response at North East Ambulance Service, tells Carbon Brief:
“During periods of hot weather, we typically see an increase in calls from people affected by dehydration, heat exhaustion and heatstroke, as well as those whose existing health conditions, particularly heart and respiratory illnesses, can be made worse by prolonged high temperatures.
“Older people, young children and pregnant people can be especially vulnerable.”
Ambulance teams are generally busier in the winter because cold weather and seasonal illnesses drive up the number of severe medical emergencies.
However, the data from June shows that extremely hot days are starting to match or even edge out cold ones as the busiest days. This is a trend seen across the healthcare system.
While not every service provided records back to 2019, the data broadly shows that ambulances were busier during the heatwave than at the height of the Covid-19 pandemic.
As well as patients, heatwaves put pressure on ambulance workers. The UNISON union has warned of crews facing “stifling heat with faulty or no air conditioning” and “back-to-back callouts” due to increased demand.
Methodology
Carbon Brief requested data on the top 50 busiest days for England’s 10 main ambulance services.
These are: London; South East Coast; South Central; South Western; West Midlands; East Midlands; East of England; North East; Yorkshire; and North West.
Data was requested for as far back as service records go. Most were able to provide records going back to some point in the 2010s, with the exception of North East and South Central, which only had records from 2021 and 2022 onwards, respectively.
Rising annual demand for ambulance services means that most of the busiest days for ambulances have been in the 2020s. For example, all but four of the busiest days for category 1 emergencies reported to Carbon Brief were in the 2020s.
Carbon Brief requested data on ambulance demand for all the UK nations. In Scotland and Northern Ireland – where temperatures are cooler – services did not see call volumes reach the top 50 rankings during the June heatwave. The Welsh Ambulance Service did not respond to Carbon Brief’s request.
