China’s role at COP29 and beyond
‘COOPERATIVE’ COP: China’s “role” at the COP29 climate talks, which concluded over the weekend in Baku, Azerbaijan, was “markedly different to previous years”, with its negotiators being “unusually cooperative”, according to an anonymous “chief negotiator” for a “powerful” country quoted by BBC News. Bloomberg cited sources “close to the Chinese delegation” explaining that “Chinese officials moved to soothe angry delegations from India, Saudi Arabia, Africa and the small island group” during the tense final plenary. It added that China’s delegation head Zhao Yingmin, who is also the vice minister of the Ministry of Ecology and Environment (MEE), held “one-on-one conversations with delegates in the final hours to warn things would be worse without COP29’s finance agreement”. COP29 president Mukhtar Babayev wrote in the Guardian that China “coordinat[ed] their response to the negotiations…with the G77 group”. Babayev also claimed that “the Chinese were willing to offer more [climate finance] if others did so too”. (For more on China’s role at COP29, see the Spotlight.)

GLOBAL CALLS: As concerns over the US’s future role loomed over the two-week summit, UN climate chief Simon Stiell said the world “will need China’s continued leadership” to meet climate goals, Politico reported. This was echoed by South Africa’s environment minister, who said China “has an opportunity to lead the global fight against climate change”, according to Bloomberg. BBC News quoted Jonathan Pershing, program director of environment at the William and Flora Hewlett Foundation, saying that, should China become the de-facto leader at future COPs, it “won’t lead from the front, like the US and Europe”, but instead would “discreetly interven[e] to unblock disputes…behind closed doors”.
CHINA’S REACTION: In response to Stiell, Politico quoted Zhao saying: “China has contributed in addressing climate change. But, in the future, China will do our best to contribute more.” Zhao also said in an interview with business news outlet 21st Century Herald that China will be “the backbone of the global response to climate change”. Nevertheless, Chinese climate envoy Liu Zhenmin told Beijing News that “people expect China and the EU to work together to fill this gap [of US leadership], which is a very good wish, but, in practice, it is very difficult”. (Read more in the Spotlight below.) China’s foreign ministry noted that agreements at COP29 demonstrated global “willingness” to address climate change, although it added that developed countries should “effectively fulfil their obligations and responsibilities”, Shanghai-based news outlet the Paper said. A commentary in the party-affiliated People’s Daily under the nom de plume “Heyin”, which is used for articles expressing the view of party leadership on international affairs, said COP29 “consolidated the momentum” of the global energy transition, adding that “no matter how the [geopolitical] climate changes, China’s determination…to actively address climate change will remain unchanged”. Elsewhere, an editorial in the state-run newspaper China Daily argued COP29 was an “unusual climate diplomacy success” as it broke “the long-standing multilateral negotiations stalemate over climate financing”.
New China research
EARLY PEAK: Meanwhile, on the sidelines of COP29, an assessment by research institute the Centre for Research on Energy and Clean Air (CREA) of China’s energy transition in 2024 found that the clean energy industry “continued to exceed forecasts”, but that spiking energy consumption meant record additions served only to “stabilise emissions, not to push them down”. It added that 52% of experts surveyed by CREA expected China’s coal consumption to peak by 2025 and 44% believe China’s carbon emissions have already peaked or will peak by 2025.
POLLUTING PROVINCES: Al Gore-backed research institute Climate Trace released a report finding that Shanghai was the world’s “most polluting” city, Fortune said. It added that “seven states or provinces spew more than 1bn metric tonnes of greenhouse gases [per year]”, six of which are in China – the exception being Texas.
POWER SYSTEM REFORM: The International Energy Agency also presented a report at COP29 examining the “evolving flexibility requirements of China’s power system” during its energy transition, finding that “non-fossil resources, such as hydropower, battery storage and demand response, could fulfil nearly 60% of [China’s] short-term flexibility needs by 2030”, according to a press statement.
‘INSUFFICIENT’ SPEED: The 2024 Global Carbon Neutrality Progress Report, released by Beijing’s Tsinghua University, evaluated progress in 151 countries that have set carbon neutrality targets. The report said that developing countries have higher “ambitions” and willingness to reduce emissions than developed countries. However, it added that the “current speed of renewable energy development globally is insufficient” to meet the target of tripling renewable energy capacity by 2030 – a goal set at COP28 in an effort to limit global warming to 1.5C.
Xi at APEC and G20
SUNNIER CLIMES: As his subordinates hashed out details in Baku, President Xi Jinping’s attendance of the APEC economic leaders’ meeting in Peru and G20 summit in Brazil “fuelled expectations that China will continue championing…better global governance”, China Daily said, adding that during APEC Xi “emphasised the importance of innovation, openness, green development and inclusive growth”. Xi also inaugurated Peru’s Chancay port – built by a Chinese company – as Beijing “look[s] to further tap into resource-rich Latin America”, Reuters reported. At the G20 summit, Xi noted the importance of supporting developing countries in “responding to…climate change, biodiversity loss and environmental pollution”, state news agency Xinhua said. China also signed 37 agreements with Brazil, according to the Associated Press, which included specific agreements on mining, solar and nuclear power.
UK-CHINA TIES: In the first high-level meeting between the UK and China since 2018, UK prime minister Keir Starmer told Xi that the UK “would like to engage with Beijing on areas such as trade, the economy and climate”, Reuters reported. Starmer told the UK House of Commons that the two countries need to “work together on challenges such as climate change and delivering growth”, adding that he and Xi “agreed a new dialogue on these issues, which [UK chancellor Rachel Reeves] will take forward with vice premier He [Lifeng] in Beijing” next year, according to a transcript of his remarks.
‘Disorderly expansion’ of solar factories targeted
RAISING REQUIREMENTS: China’s Ministry of Industry and Information Technology (MIIT) raised minimum capital requirements for construction and expansion of solar-manufacturing projects, the Hong Kong-based South China Morning Post said, adding that MIIT also urged manufacturers to limit projects that are “merely meant to increase capacity”. Lin Boqiang, director of Xiamen University’s China Energy Policy Research Institute, told business news outlet Yicai the move will “control the disorderly expansion of production capacity”.
LOWERING REBATES: China’s finance and tax bodies also “announced a reduction in the export tax rebate” for solar products, “squeezing profit margins” and possibly leading to companies “increasing export prices”, PV Magazine reported, in what may be “part of a longer-term strategy”. Finance news outlet Wall Street CN noted that rebates for batteries will also shrink, but that manufacturers will still have a “price advantage in overseas markets”.
EXPERT VIEWS: Liu Shijin, former vice-president of the Development Research Centre (DRC) and chief advisor at the China Council for International Cooperation on Environment and Development (CCICED), said in a speech covered by Yicai that “overcapacity” is a “normal process of market competition”, adding that the government should avoid “disturbing” industries through “administrative intervention and unfair competition”, and instead encourage market expansion by “accelerating the shift from dual-control of energy consumption to dual-control of carbon emissions”.

COP29: How China approached the UN climate talks in Baku
As ever at COPs, a key question was how the world’s current largest annual emitter, China, would approach the talks. This year, with Donald Trump being reelected as the US president, more expectations fell on China to step up and do more.
In this article, Carbon Brief summaries some of the key points China made at COP29. This is a summary of “China at COP29” in Carbon Brief’s in-depth summary of the event’s key outcomes.
China arrived at the COP29 UN climate talks in Baku with the fifth-largest delegation, continuing its recent trend of major showings at the annual summit.
At the high-level opening of the talks, China’s vice premier Ding Xuexiang – who is president Xi Jinping’s “special representative” at COP – declared that his country had “provided and mobilised project funds of more than 177bn yuan ($24.5bn) for developing countries’ climate response” since 2016.
This was the first time China used the language of climate finance to talk about its overseas aid. It quickly drew attention to Beijing’s intentions and levels of ambition for climate finance.
Kate Logan, director of the China climate hub at the Asia Society Policy Institute (ASPI), wrote on Twitter that this placed China “on the same order – if not higher than – many developed countries’ efforts” on climate finance.
Dialogue Earth reported that Beijing has contributed more than $30bn to global climate finance since the launch of its “Belt and Road Initiative”, putting China “on a par with the UK, to become the joint fifth-largest provider of climate finance after Japan, Germany, the US and France”.
However, entering week two, China’s stance on climate finance remained firm – it said it would not agree to make any compulsory contributions, including to the new climate finance goal (NCQG) that was being negotiated at the summit.
China’s new climate envoy Liu Zhenmin, replacing Xie Zhenhua, told the Paper, a Shanghai-based outlet, that paying for the NCQG was “their business”, referring to developed countries.
During the closing stages of COP29, Xia Yingxian, director of the department of climate change of the Ministry of Environment and Ecology, said that a serious climate finance offer from developed countries was the “master switch and golden key” to a deal in Baku.
Liu was also quoted by state-run newspaper China Daily, saying China is “not obliged to contribute to the post-2025 climate financing target that is expected to be announced during COP29”.
At the closing plenary, Carbon Brief heard Zhao Yingmin, head of Chinese delegation and the vice minister of the Ministry of Ecology and Environment (MEE), saying that developed countries’ NCQG commitments were still “fall far short of meeting the needs of developing nations” and that developed countries’ “financial obligations must be further clarified”.
Nevertheless, China said it remained open to multilateral cooperation on climate change.
Chen Zhihua, deputy director of China’s National Centre for Climate Strategy and International Cooperation, told Carbon Brief that Donald Trump being reelected as the US president “certainly is a big thing that people talk about and [we] have concerns about how things will turn out”.
He added: “It will have big impacts, but China won’t change its strategy – we will cooperate with whoever for global cooperation on climate change.”
Wen Hua, deputy director-general of the Department of Resources Conservation and Environmental Protection at China’s top planner the National Development and Reform Commission (NDRC), said at another event attended by Carbon Brief: “China is willing to take a more active role in global climate governance.”
Throughout COP29, China strongly identified itself as a developing country. China, together with the G77 group of developing counties, rejected an initial draft for the NCQG framework. According to BBC News, they wanted “public grants of $500bn per year”.
At the South-South Cooperation on Climate Change forum hosted by China, Carbon Brief heard Huang Runqiu, minister of the MEE, saying that the world needs multilateral cooperation on combating climate change, but that “green trade barriers” prevent better cooperation, especially for developing countries.
Wang Can, director of the department of environmental planning and management at Beijing’s Tsinghua University, explained to Carbon Brief that the “green trade barriers” are “bans and tariffs…mainly from the US” on renewable technology products.
Both Chinese academics and multiple senior officials expressed their desire for international cooperation on energy transition at COP29.
For example, Wen called the energy transition “fundamental” for China at an event hosted by the country’s COP29 pavilion.
China also stated some of its specific targets and actions for addressing climate change, such as the latest emissions standards for coalbed methane introduced by Liu at a methane summit held during COP29.
Regarding China’s next NDC, an anonymous scholar told Carbon Brief that shifts in the new pledge could lie in “adjusting the timeline of [the] ‘dual-carbon’ goal”, which currently targets a peak in emissions “before 2030” and carbon neutrality “by 2060”. (For more views, see Carbon Brief’s “Experts: What to expect in China’s climate pledge for 2035.”)
China has already adjusted its “dual-carbon” goal from “achieving carbon peak by 2030” to “before 2030”. Bai Quan, director of the Energy Research Institute of the Academy of Macroeconomic Research (AMR), a government-affiliated “national high-end thinktank”, told Carbon Brief that while “we would love to try our best…we can’t rule out all possibilities to peak even earlier than planned”.

China’s historical carbon dioxide (CO2) emissions within its borders are now higher than the 27 member states of the EU combined, new Carbon Brief analysis found, although it is “still far behind” and “unlikely to ever overtake” the US total. The analysis – which was covered by the New York Times under the headline: “China’s soaring emissions are upending climate politics” – noted that when viewed on a per-capita basis, using 2024 figures, China’s contribution is “just 227tCO2 per capita, less than a third of the 682tCO2 for people in the EU27”.

The number of extreme weather events in China that had their “severity or likelihood” increased by climate change, out of a total of 114 attribution studies covering the country, according to Carbon Brief analysis. The figures come from Carbon Brief’s updated “attribution map”, which covers every attribution study published since the method was developed in 2004. The map includes more than 600 studies, with China making up 16%. More than 70% of the China-focused studies were published in the past four years, significantly higher than average.
New science

The number of heat-related diabetes deaths in Chinese cities is expected to increase by the end of the century as a result of global warming, a new study warned. The authors predicted deaths due to extreme heat over 2010-2100 in 32 “major” Chinese cities. They projected that under the low warming SSP1-2.6 scenario, the heat-attributable fraction of diabetes deaths will rise from 2.3% in the 2010s to 4.6% in the 2090s. Under the high warming SSP5-8.5 scenario, the fraction could rise to 19.2% in the 2090s, they added.
Communications Earth & Environment
Electric vehicles in China have nearly a 12% reduction in CO2 as compared to internal combustion engines, according to new research. Researchers carried out a life-cycle analysis of internal combustion engines, plug-in hybrid vehicles and battery EVs in each of China’s provinces. They found that while battery EVs reduced CO2 and nitrogen oxide emissions, they had higher emissions of sulphur dioxide and particulate matter. The authors wrote that “improving technological progress and optimising electricity mix will greatly assist in achieving emissions reduction”.

Climate Change
Q&A: Does the world need ‘carbon capture and storage’ to reach net-zero?
When carbon dioxide (CO2) is released from a factory or power plant, the gas can be captured and permanently stored underground, preventing it from driving climate change.
This is the idea underpinning carbon capture and storage (CCS), a technology that is at the heart of many nations’ net-zero plans.
Influential organisations, including the Intergovernmental Panel on Climate Change (IPCC), describe CCS as “critical” for cutting emissions from key sectors – and for helping to avoid dangerous global warming.
In particular, capturing CO2 is seen as one of the only viable options for decarbonising some of the world’s highest-emitting industries, such as cement production.
The UK, for example, has committed to investing as much as £21.7bn over the coming decades in its nascent CCS industry, as part of the nation’s net-zero strategy.
Yet, in the UK and elsewhere, there has been a backlash against plans for CCS.
Citing high costs, ties to the fossil-fuel industry and a “history of poor performance”, critics describe CCS as a “dangerous distraction” or a “false climate solution”.
Time and again, the outlook for the roll-out of CCS has been scaled back, as the technology has failed to deliver as quickly as expected – and as policy support has wavered.
Furthermore, critics state that the technology remains “unproven” on the scale required to make a meaningful impact on global emissions.
In this Q&A, Carbon Brief explores the role CCS is expected to play in achieving net-zero, its record to date and the reasons it has been criticised, using the UK as an example.
What is CCS?
CCS involves capturing CO2 emissions released from a large source, such as a gas power plant or a cement factory.
The CO2 is separated from the facility’s exhaust stream, generally using a chemical solvent, before being compressed into a liquid and transported via pipeline or vehicle. The CO2 is then stored by injecting it into underground reservoirs, such as depleted oil fields or saline aquifers.
The term “CCUS” is sometimes also used, referring to the “utilisation” of CO2 to make products, including fertilisers, fuels or building materials. Such uses do not necessarily lead to permanent emissions cuts, as the CO2 can end up later being released back into the atmosphere.
(“CCS” is used in this Q&A, unless quoting another organisation that specifically refers to “CCUS”.)
The infographic below shows the stages of capturing CO2 and transporting it to be either stored or used in other applications.

Carbon capture technology was originally rolled out at US and Canadian oil wells in the early 1970s as a way to achieve “enhanced oil recovery”. This involves injecting captured CO2 into depleted wells – a process that stores CO2, but also helps to extract more oil.
This remains, by far, the most significant end use for captured CO2 worldwide, with around three-quarters of it used for this purpose.
Moreover, most of the CO2 currently captured is a by-product of gas purification – the process by which fossil fuels such as methane are separated from other, unwanted substances. Selling this CO2 can make such gas projects more economically viable.
Therefore, as shown in the chart below, which is based on International Energy Agency (IEA) data, the majority of CO2 that is both captured and used today helps the fossil-fuel industry to extract and sell more oil and gas.

CCS was first proposed as a way to deal with CO2 emissions in a 1976 academic article, which imagined injecting the captured gas into the ocean.
It is only since the early 2000s that CCS has gained traction as a proposed climate solution, with a 2005 “special report” by the IPCC exploring the topic. At that time, the authors note there were just three small-scale projects trying to capture and permanently store CO2.
Installing CCS at factories or power plants and permanently storing the CO2 would mean that, in theory, such facilities could continue using fossil fuels without contributing to climate change.
Such applications are often mentioned alongside two related technologies, both of which could be used to “suck” CO2 out of the atmosphere and, thus, deliver “negative emissions”.
One is bioenergy with carbon capture and storage (BECCS). Crops absorb CO2 as they grow and BECCS involves a power plant burning these crops, then storing the resulting CO2.
The other technology is direct air carbon capture and storage (DACCS).
These technologies are classed as “CO2 removal”, as they involve absorbing CO2 from the atmosphere using plants or machines and then storing it permanently.
By contrast, CCS installed at a factory is considered a way to avoid CO2 emitted by that specific facility from entering the atmosphere. This Q&A focuses on such applications, which account for the vast majority of existing and planned CCS.

How much CCS capacity has been built so far?
As of February 2026, there were a total of 75 operational CCS projects around the world. As noted above, almost all of them are at fossil-fuel extraction and processing sites, according to the IEA’s database.
Together, these projects capture 62.5m tonnes of CO2 (MtCO2) each year. This is equivalent to the annual greenhouse gas emissions of Ecuador.
(This compares with the 22 CCS projects, promising to capture 40MtCO2 annually, that were operational or under construction as of 2014.)
As the chart below shows, the amount of CO2 currently being captured and stored is a tiny fraction of the total emissions from fossil-fuel use.

In a 2020 report, the IEA explained that the “story of CCUS has largely been one of unmet expectations: its potential to mitigate climate change has been recognised for decades, but deployment has been slow”.
A wave of interest in CCS in the 2000s, largely from countries in Europe and North America, focused on enabling coal power plants to continue operating with lower emissions.
This interest largely petered out, as plummeting renewable energy costs weakened the case for coal plants with CCS. Today, there are only seven operating CCS-coal plants worldwide – five in China, one in the US and one in Canada.
Yet the Paris Agreement in 2015 – and the national net-zero targets that followed – highlighted the need for deep emissions cuts in sectors that previously expected to continue emitting for decades. This, once again, has fuelled interest in the use of CCS.
In recent years, there has also been growing interest in producing low-carbon “blue” hydrogen from gas with CCS.
Hydrogen is widely seen as key for decarbonising certain sectors – particularly in industry – but analyses suggest that it may be difficult to make sufficient “green” hydrogen using renewable power on the timescales required.
As the map below shows, most CCS capacity is based in the US and Canada, with other major fossil-fuel producers such as Norway, Brazil and the Gulf states also contributing.

A surge of projects have entered the global CCS pipeline in recent years. According to the IEA, 93.7MtCO2 of capture or storage capacity is under construction as of February 2026 and another 1,279.6MtCO2 is in the “planning” stages.
“Planned” projects include any initiative at early concept, feasibility or engineering study stages and the industry has a long history of projects being cancelled or delayed.
Nevertheless, this pipeline of projects could lead to a large expansion of facilities dedicated to permanent CO2 storage that does not involve extracting more oil.
The planned projects – if they are realised – would also include significant growth in sectors where CCS is virtually non-existent, such as steel, hydrogen and cement production, as shown in the chart below.

What role is CCS expected to play in reaching net-zero?
It will be impossible to stop dangerous climate change unless the world reaches net-zero emissions, according to the IPCC. The amount of global warming – and whether the Paris Agreement temperature target can be met – depends on when net-zero is reached.
Many global pathways that have been set out for achieving net-zero, including a majority of the IPCC-assessed pathways where global warming is limited to 1.5C, rely on the use of CCS at fossil-fuel plants and industrial sites.
“These models have been quite instrumental in bringing CCS back onto the agenda,” Lina Lefstad, an ecological economist at Lund University, tells Carbon Brief.
Influential organisations relying on CCS in their net-zero scenarios range from the International Renewable Energy Agency (IRENA) through to the oil company Shell. The IEA has stated that net-zero would be “virtually impossible” without CCS.
These scenarios often include 10s to 100s of times more CCS capacity being built in the coming decades. The IEA includes 1.7GtCO2 being captured by 2035 in its net-zero scenario – nearly 30 times more than is captured today.
(Some of the much higher numbers in scenarios assessed by the IPCC have been dismissed by experts as implausible, especially given the slow rollout of CCS to date.)
When considering CCS for both emissions cuts and removals, Dr Jennifer Roberts, a researcher at the University of Strathclyde and deputy director at the UK Carbon Capture and Storage Research Centre (UKCCSRC), tells Carbon Brief the situation is clear:
“From an IPCC climate modelling perspective…reaching net-zero without CCS is far more expensive, disruptive and potentially out of reach.”
This does not mean that it would be impossible to reach net-zero without using CCS. However, net-zero scenarios that use little or no CCS rely on dramatic changes elsewhere, such as much lower global energy demand.
Net-zero scenarios often include a crucial role for CCS in “hard-to-abate” sectors, referring to activities that lack available, low-cost options to fully decarbonise. In particular, CCS is widely seen as vital for decarbonising parts of heavy industry.
The IPCC sixth assessment report (AR6) summary for policymakers calls CCS a “critical mitigation option” for some sectors, including cement and chemicals. The technical summary of the AR6 Working Group III report says that “CCS will be required to mitigate remaining CO2” in industrial sectors.
The IEA describes CCS as “virtually the only technology” that can significantly cut cement emissions, which account for around 7% of the global total. (Much of this CO2 comes from chemical processes, meaning it would still be released if the industry was electrified.)
Yet, the understanding of “hard-to-abate” emissions is changing, as alternatives to CCS become cheaper and increasingly available. As a result, CCS has become a less attractive option in some sectors, as well as being seen as less vital in some others.
Carbon Brief analysis shows that the IEA has reduced its outlook for CCS in the power sector by a third, compared to its expectations in 2021, as the chart below shows.
This reflects both slow progress in deploying CCS and rapid cost reductions in renewables, which make running gas or coal power plants less attractive.

(Even prior to this adjustment, the IEA’s net-zero scenario was already at the lower end of CCS use, compared to those assessed by the IPCC.)
This declining role for CCS in the power sector would mean its use is more concentrated in industry.
Industrial sectors – particularly cement, steel and chemicals – account for 60% of the CO2 captured in 2050 under the IEA’s net-zero scenario, as shown in the figure below. The remaining 40% is roughly split between electricity generation and blue hydrogen production.
Climate NGOs Bellona and E3G have stressed that with “limited public funding, infrastructure constraints and political attention, prioritisation is essential” for CCS. Their “CCS ladder” places CCS in cement and lime production at the top – with the highest “climate value” – while power CCS has “low and decreasing value”.
Despite this, the focus of the CCS sector so far has not been in heavy industry, which represents less than 10% of announced capacity.

Another key consideration is the role governments are assigning to CCS in their national net-zero strategies.
One study found that 33 of the 67 long-term net-zero strategies submitted to the UN by governments, with a further 10 indicating some potential use.
It concluded that high-income countries that produce a lot of oil and gas, such as Canada and Norway, showed the “firmest commitment” to capturing and storing CO2.
Nations have agreed at UN climate talks to “phase down” coal power that is “unabated”. This is generally understood to mean coal power without CCS – leaving space to develop “abated” coal plants. This could allow China, for example, to continue using its sizable coal fleet with CCS to reduce emissions.
Why is CCS controversial?
Despite its role in many net-zero scenarios, CCS remains a highly contested technology.
It has long been framed in some circles as a “false solution” to climate change, that is backed and lobbied for by fossil-fuel companies to “delay” the clean-energy transition.
Critics argue that CCS is expensive – especially compared to increasingly cheap wind and solar power – in part because it significantly increases the energy requirements of a facility.
A University of Oxford working paper published in 2023 concluded that a “low-CCS” pathway to net-zero emissions would cost around $1tn less a year compared to a “high-CCS” pathway. The researchers stated that “no evidence is found for technological learning or associated cost reductions” in the development of CCS to date.
(They added that CCS is “still likely necessary” for cement and chemical production.)
Pointing to the limited progress in scaling up the technology so far, some question whether CCS can play the role envisaged in many net-zero scenarios.
Responding to the IPCC’s most recent report, for example, the Centre for International Environmental Law stated that “abated fossil fuels only exist in models”.
Proponents of CCS contest the notion that CCS is “untested” or “unreliable”, pointing to some projects that have been operating for many years. Moreover, most of the component parts that make up a working CCS project are in wide use for other purposes.
Yet, another key criticism levelled at CCS projects is that they simply do not capture enough CO2, diminishing their role as a climate solution.
There is a widespread view that CCS projects should aim to capture at least 90% of the CO2 being emitted. UK guidelines are among those targeting a higher capture rate of 95%.
The Institute for Energy Economics and Financial Analysis (IEEFA) has assessed the performance of existing projects. Its 2023 analysis is shown in the chart below.
The thinktank concluded that, in reality, most existing CCS projects are far below such capture rates, meaning they continue to emit significant amounts of CO2. (Capture is the most expensive part of the CCS process.)

Once the CO2 is captured, it must be stored. The IPCC says there is ample global geological storage available for CO2. It also says that, as long as sites are “appropriately selected and managed”, CO2 “can be permanently isolated from the atmosphere”.
Nevertheless, critics have noted that even relatively low rates of leakage along the transportation and storage chain could have a big climate impact when deployed at scale.
The continued use of gas in gas-CCS or blue hydrogen projects also brings risks of upstream emissions more broadly, such as methane leaks. (See: What are the UK’s plans for scaling up CCS?)
Considering these factors, in 2023 Climate Analytics assessed a “high CCS pathway” from the IPCC database. It concluded that if CO2 was captured at rates seen in existing facilities – around 50% – and upstream emissions remain high, CCS use could see an extra 86GtCO2e emitted by 2050.
The report found that even the IEA’s net-zero scenario, which relies on “more limited fossil CCS use”, could result in an additional 16GtCO2e due to “underperforming fossil CCS”.
All of this calls into question many uses of CCS, according to Andrew Reid, energy finance analyst at IEEFA: “Is there really any point in trying to decarbonise fossil fuels, which comes with significant technical, timing and additional cost risk?” Reid tells Carbon Brief:
“As for cement and chemicals, again, there are alternatives, but these are nascent and expensive. CCS may be a solution here and if investment is going to be made in any area, it most likely should be these.”
On the other hand, CCS advocates argue that gas, for example, is likely to be an important, “dispatchable” part of many electricity systems as nations transition to clean energy.
Prof Stuart Haszeldine, a CCS researcher at the University of Edinburgh, explains this position to Carbon Brief:
“If we’re going to burn gas, then we should be fitting CCS on that…Otherwise we’re just going to say it’s OK for us to burn lots of gas and carry on emitting.”
There is also a line of argument referred to – sometimes pejoratively – as “techno-optimism”, which often stresses CCS as a core climate solution. This was exemplified by a controversial report on climate action in 2025 by the Tony Blair Institute for Global Change (TBI), in which the former UK prime minister wrote that CCS should be “at the centre of the battle”.
This diverges from the IPCC’s conclusion that, while CCS will likely have a role in achieving net-zero emissions, its contribution will be dwarfed by that of renewables.
CCS also attracts criticism due to its connection to the fossil-fuel industry. Dr Jen Roberts at the UKCCSRC tells Carbon Brief that she agrees these links make for complicated messaging:
“CCS is critical for net-zero, but is intrinsically tied with an industry sector that is climate polluting and historically anti-climate lobbying.”
Roberts says careful policymaking, including the development of business models and standards, can support CCS in hard-to-abate sectors where it is most needed.
Some experts suggest that governments should require companies to capture and store their emissions under the “polluter pays” principle.
Roberts also notes that fossil-fuel companies have the experience and the workforce needed to scale up CCS. “Oil and gas companies can evidence a track record in multi-million or billion-dollar subsurface engineering projects,” Roberts adds.
Despite the fossil-fuel industry’s apparent support for CCS, one 2021 study co-authored by Haszeldine noted that they had, in fact, invested relatively small amounts in the technology, compared to renewables and nature-based solutions.
Lina Lefstad at Lund University questions whether the fossil-fuel industry stands to benefit financially through the deployment of CCS as much as some critics imply:
“People seem really worried that the fossil-fuel industry is going to come out the winner again, but if that was the case I think we would have large-scale CCS by now.”
What are the UK’s plans for scaling up CCS?
The UK government has committed “up to” £21.7bn of funding over 25 years to support the nation’s first five CCS projects and to make the nation an “early leader” in the sector.
This package, supported by both the former Conservative and current Labour governments, is intended to help create “clusters” of connected facilities across industrial areas of the UK.
Some have suggested that this represents a large pot of government spending, which could be raided to support more pressing priorities. Indeed, media coverage often points to CCS funding as a potential target for government cuts, or as a way to boost, say, military spending.
This is in spite of the fact that three quarters of the funding is expected to come from levies on consumers, rather than government budgets.
The first two CCS clusters, which are currently set to be deployed in the late-2020s, are the East Coast Cluster in north-east England and HyNet in north-west England and north Wales. The second two, scheduled for around 2030, are Acorn in north-east Scotland and Viking in the Humber.
The projects are expected to include blue-hydrogen production, gas power with CCS and industrial uses. The CO2 captured would be pumped into offshore saline aquifers and depleted gas fields.
Former UK energy secretary Ed Miliband has stated that CCS will “unlock” hard-to-abate sectors and play an “important role” in achieving clean power by 2030.
This position is supported by the UK government’s climate advisors at the Climate Change Committee (CCC), who have consistently stressed that CCS is “essential” for net-zero.
In the CCC’s most recent net-zero pathway, released as part of its seventh carbon budget advice, CCS contributes 2% of emissions cuts in 2030 and 8% in 2050, as shown in the chart below. (If CO2 removals using BECCS are included, this increases to 15% in 2050.)

The CCC maintains that it “cannot see a route to net-zero that does not include CCS”. Nevertheless, the committee has downgraded its expectations for CCS in recent years.
Between the CCC’s sixth and seventh carbon budget advice, its recommendations for power and industry CCS capacity dropped from 46MtCO2 to 41MtCO2.
Dr Jamie Tarlton, the committee’s CCS lead, addressed this at a conference in March 2025, stating that it was “partly because we see more opportunities for decarbonising the other sectors and reducing those residual emissions than we saw five years ago”.
More recently, the UK government also scaled back its expectations for industrial CCS in its latest carbon budget delivery plan for 2035, bringing it more in line with the CCC’s net-zero pathway. It still describes CCS as “part of the most cost-effective route to net-zero”.
The UK’s CCS plans have drawn criticism. A September 2024 letter to Miliband signed by 22 scientists and activists expressed concern about “locking the UK into a fossil-fuel based pathway”.
They note that the gas-CCS power plants and blue hydrogen facilities initially backed by the government would leave the UK reliant on gas imports, as North Sea production declines. This could be expensive and result in “upstream” emissions due to methane leaks.
(At the end of 2025, BP withdrew its involvement in one of the blue hydrogen facilities at the Teesside site. A data centre is planned for the site instead.)
Net Zero Teesside, a gas-CCS power plant in the East Coast Cluster run by BP and Equinor, has been unsuccessfully challenged in court over its emissions savings. The challenge was based on the idea that potential upstream emissions could significantly exceed any emissions cuts from CCS use.
According to a report by Carbon Tracker, the lifecycle emissions of Net Zero Teesside gas-CCS power plant would depend heavily on where it sources its fuel.
The project could cut emissions by around three-quarters, relative to an unabated gas plant, says the report. But it adds that if the plant relies on imported gas with high upstream emissions, then it might only cut emissions by a quarter.
(Most of the upstream emissions from imported gas would be released overseas, meaning they would not be counted in the UK’s official emissions inventory.)
Besides driving “gas dependence” in the UK, the government’s approach has drawn criticism for failing to ensure that CCS is prioritised in the industries that are hardest to decarbonise.
A report by the Public Accounts Committee in early 2025 took aim at the government’s cluster-based approach. It said this “does not ensure that financial support for CCUS is directed at the sectors which will need it most” – highlighting cement production.
(Of the CO2 captured in the CCC’s net-zero pathway in 2050, around 40% is in the industrial and waste sectors, while the remaining 60% is from gas power plants and the production of fuels such as hydrogen.)
Dr Andrew Boswell, the energy analyst who challenged Net Zero Teesside in court, says he is “more nuanced” when it comes to applications of CCS that do not involve gas. “There may be a case for cement, lime and waste…However, the case is unproven,” he tells Carbon Brief.
The Public Accounts Committee report also criticised the “high-risk” approach of using public funds for CCS projects, as well as slow progress in developing the technology.
Enrique Cornejo, head of energy policy at fossil-fuel trade body Offshore Energies UK, tells Carbon Brief that the UK needs to maintain momentum and deploy CCS in order to “achieve economies of scale” and to reduce the cost of the technology more broadly:
“It is indeed necessary to streamline the cluster sequencing process to ensure that emitters in sectors such as cement have a clear route to the CCS market.”

Egypt seeks to unlock renewable potential to power regional clean energy hub
After the US-Iran war caused energy prices to soar, ballooning Egypt’s energy import bill, the government has doubled down on plans to boost renewable energy in the country’s power mix – part of its broader plan to become a clean energy export hub for the region.
With abundant sunshine, swathes of unused desert land and plenty of wind, Egypt is seen as having the potential to become a major force in renewable power generation, helping to cut the planet-heating carbon emissions of Africa’s second-largest economy and beyond.
The conflict in the Middle East has given the government’s clean energy plans more salience, making the case for renewable power to bolster the country’s energy security and help it meet its economic development goals by exporting clean power.
The government recently announced an accelerated timeline for renewables to reach 45% of the electricity mix within two years – up from a previous target of 42% by 2030 and a huge jump from around 13% in 2025, according to think-tank Ember.
In June, President Abdel Fattah el-Sisi met with government ministers to discuss the faster delivery of solar and energy storage projects as well as upgrades to the electricity grid to deliver on the new goal, including 105 renewable energy projects intended to bolster grid stability.
Big challenges lie ahead, among them a parallel bet on continued fossil fuel exploration and the need to upgrade electricity infrastructure, a task that could require multibillion-dollar investments, experts say.
“The technical and financial plumbing – the grid, foreign-currency financing and the supply chain – are the real gatekeepers,” Nadia Elmasry, an expert at the Regional Center for Renewable Energy and Energy Efficiency, told Climate Home News.
In a speech to the nation in March, President Sisi said $50 billion worth of investment were needed to overhaul the electricity grid and transmission infrastructure.
During the COP29 climate talks in 2024, Prime Minister Mostafa Madbouly warned that Egypt’s targets for renewable power expansion could be missed without more international support for critical infrastructure.
Multimillion-euro investment
Modernising and expanding power grids has emerged as a central pillar of an intensifying global push for electrification – a key priority of the COP31 UN climate talks taking place in Türkiye in November.
As dozens of governments led by the European Union and the UK throw their political weight behind a rapid electrification of the global economy, Egypt’s hunt for foreign investment in power infrastructure has found sympathetic ears.
In June, the EU and its European Investment Bank lending arm announced a financing package of up to €690 million ($795 million) to modernise Egypt’s transmission network – widely seen as a weak point in the nation’s clean energy ambitions.
The project aims to help the grid absorb 22 GW of renewable capacity by 2030, reduce electricity losses and move power from wind and solar zones to consumers and, eventually, foreign markets, including the EU.
New substations and transmission lines will connect wind and solar zones around the Red Sea and the Gulf of Suez, reducing losses and preparing the network for future cross-Mediterranean trade.
Under the country’s ambitious regional plans, Egypt would supply clean power via existing interconnections with Jordan, Libya and Sudan, as well as a 3 GW link under construction with Saudi Arabia.
Further ahead, proposals envision the export of renewable electricity to southern Europe via a subsea cable, and Egypt also aims to be a primary source of green hydrogen and ammonia for European markets.
Conflicts, cash among the challenges
Planned investment in electricity and renewables reached 136.3 billion Egyptian pounds ($2.7 billion) for the 2025/26 financial year, up from 72.6 billion pounds ($1.4 million) the year before, with public investment expected to account for about three-quarters of that.
Grid investment is “the cornerstone” of Egypt’s hub strategy, said energy and environmental economy expert Mohammed Abdel Raouf, allowing it to integrate renewables without destabilising the power system and create the smart-grid infrastructure needed to trade electricity with other countries.
But Egypt’s plans face several major challenges, besides the necessary grid upgrades, which are estimated to cost billions of dollars alone, according to a December 2025 study by the Amsterdam-based think-tank Transnational Institute.

Regional conflicts are disrupting supply chains and discouraging investment, particularly in renewable energy, Abdel Raouf warned. High borrowing costs, financing rules, limited EU-compliant capacity and uncertain long-term buyers of Egypt’s clean power could also slow progress, according to the Transnational Institute study.
The Arab world’s most populous country has been grappling with the aftermath of a steep currency devaluation and economic fallout from the Gaza and Iran wars.
Elmasry pointed to pressures from Egypt’s shortage of foreign currency and the need for concessional finance or guarantees to make long-term projects bankable. Egypt says it has mobilised $4 billion in concessional finance for 4.2 GW of renewable energy projects.
Regulatory coordination and workforce development will be essential, particularly as Egypt seeks to trade across grids governed by different technical and commercial rules, Elmasry added.
In order to generate an exportable surplus of clean electricity at a time of rising domestic power needs, Egypt also needs to give a bigger role to decentralised minigrid systems such as rooftop solar projects, said Cairo-based solar entrepreneur Hatem Tawfik.
“We will [only] be a hub in 2040 after we produce more than we need,” said Tawfik, co-founder and managing director of Cairo Solar, a solar engineering, procurement and construction company, calling for cheaper loans and simpler permitting and grid-connection rules.
For Tawfik, such small-scale projects are also fundamental to the government’s goal of shoring up energy security to avert crises like that of 2023/2024, when Egypt’s falling gas output contributed to rolling blackouts during sweltering heatwaves.
At a time of heightened geopolitical uncertainty in the Middle East, this is even more urgent.
“In the event of war, or if a country such as Israel, which supplies 40-60% of Egypt’s [imported] gas, suddenly cut off supplies [again], Egypt would be less vulnerable,” he told Climate Home News.

Home-grown batteries
Storage could determine whether Egypt’s renewable power is merely abundant at midday or commercially valuable around the clock.
“Storage is what turns intermittent renewables into firm, exportable power,” said Elmasry.
In January, Norwegian developer Scatec signed a 25-year power purchase agreement with the Egyptian Electricity Transmission Company for 1.95 GW of solar and 3.9 GWh of battery storage.
Demand for more storage has also raised the prospect of Egypt developing a domestic battery industry.
Chinese company Sungrow plans to build a battery-storage-system factory in Ain Sokhna, its first in the Middle East, with annual production capacity of 10 GWh and operations scheduled to begin in April 2027. It will provide the batteries for Scatec’s energy storage project.
Egypt has also granted licences for two battery-storage projects in Aswan and Suez worth a combined $800 million. Huawei and Egyptian company AIS have meanwhile signed an agreement to explore local production of grid-forming battery systems.
At the same time, Egypt is conducting an aerial geophysical survey in search of critical minerals across six regions, a first in about half a century.
Still, Mohamed Gamal Kafafy, president of the World Green Economy Council, said competing directly with China would be unrealistic, suggesting Egypt should instead manufacture under Chinese licences or through joint ventures, reducing imports while building local skills.
The Ministry of Electricity did not respond to Climate Home News’ request for comment.
Mixed messages?
The government’s climate investment programme aims to add 10 GW of renewable capacity and retire 5 GW of inefficient fossil-fuel generation by 2028, but Egypt is not turning its back on oil and gas.
President Sisi told energy companies attending the Egypt Energy Show in March to pursue a double strategy – intensifying efforts to explore and increase oil and gas production while also accelerating investment in renewable energy. The Petroleum Ministry plans to drill about 480 exploratory oil wells over five years.

The risk, Tawfik said, is that a large oil or gas discovery reduces the incentive to focus on investment in renewables.
“When a major oil or gas discovery, such as the Zohr gas field, leads to overconfidence, it reduces the focus on renewable energy,” he said, noting that renewable project rollouts largely stagnated after the completion of the giant Benban solar park in 2019.
But major developments such as the El Dabaa nuclear plant and the Abydos solar and energy-storage project demonstrate that significant work is already under way to meet Egypt’s clean energy hub ambitions, Tawfik said.
“Simply implementing the existing plans would be an excellent outcome,” he added.

UN chief warns climate crisis “in overdrive” as El Niño threatens to fuel the fire
The United Nations Secretary-General and foreign ministers from the UK, France and Spain have blamed the deadly wildfires engulfing Europe on climate change, using the disaster to renew calls for faster cuts to greenhouse gas emissions.
António Guterres told journalists on Friday that the “climate crisis is in overdrive”, adding that global heat seen so far is just a “warm up act” as a phenomenon known as El Niño intensifies “adding fuel to a planet already on fire”.
A new World Meteorological Organisation (WMO) report published on Friday predicts that the weather pattern will grow into a “strong event” between now and October, increasing the risk of higher than normal temperatures across much of the world and disrupted rainfalls.
“That risks shattering every seasonal record – and driving even more severe effects worldwide,” Guterres said.
El Niño builds on top of an already warming world, driven primarily by the burning of fossil fuels. A WMO scientist, who did not want to be named, told journalists that all the heatwaves and other climate impacts seen so far this year are “before the effects of El Niño are really kicking in at a global scale”.
Fossil fuellling the fires
Fires have broken out across much of Europe but are threatening the most people in the south-west of France near Bordeaux and in Central Spain near Madrid. Nearly a quarter of a million people have been evacuated in France with hundreds of homes destroyed while in Spain 80,000 people have had to leave their homes and at least 13 died in one village.
A scientific study published on Friday by the World Weather Attribution group found that man-made climate change made deadly fires in France twice as likely and those in Spain twenty times more likely. Smaller fires in the UK were not analysed by the study.
UN Climate Change leader Simon Stiell blamed fossil fuels for the fires, as well as storms in Chile and heatwaves in North America and Japan in recent weeks. “The climate alarm is blaring”, he said on Wednesday.
Guterres criticised new fossil fuel production projects and fossil fuel subsidies for causing hardship across the world. Discussing his speech, a senior UN official – who did not want to be named – said the subsidies amounted to trillions of US dollars a year and criticised pension funds and institutional investors, including insurance companies, for continuing to invest in fossil fuel projects.

Asked why world leaders and the public are not prioritising climate action, Guterres said they are distracted by wars in Ukraine, the Middle East, Sudan and elsewhere and sometimes forget “other aspects that are a sometimes even more dangerous threat”.
Also the fossil fuel industry and “some countries” are campaigning to pretend that climate change does not exist, he said, adding that the UN should be more active in “naming the situations as they are and the responsibilties as they are and mobilising the public opinion”.
After meetings in Paris and Madrid earlier in the week, the UK’s new foreign minister Ed Miliband issued joint statements with his French and Spanish counterparts – Jean-Noël Barrot and José Manuel Albares Bueno – calling on the world to reduce its dependence on fossil fuels.
They promised to do more to reduce emissions and protect their people and encouraged other governments to do the same.
The UK-French statement called on governments to publish UN climate plans, known as nationally determined contributions (NDCs), which are aligned with the Paris Agreement’s goal to limit global average temperatures to 1.5C above pre-industrial levels.
According to Climate Action Tracker, only three countries – the UK, Nigeria and Norway – have submitted NDCs with 2035 emissions reduction targets which are compatible with 1.5C. Fifty-two countries – including Egypt, Vietnam and Argentina – have yet to submit an NDC at all.
Defending science
Beyond action on emissions, the ministers also intervened in an ongoing dispute over the timing of the Intergovernmental Panel on Climate Change’s (IPCC)’s next flagship assessment.
Miliband and Barrot’s statement said they “underline the importance” of scientific report feeding into governments’ next global stocktake of progress on climate action in two years’ time, calling it a “critical input” to that process.
The timing of this report has been a contentious issue in government negotiations at the IPCC and at June’s climate talks in Bonn. While a group of nations calling themselves the “friends of science” want the report before the stocktake, others like Saudi Arabia and India have argued that this would make the report of a worse quality and less inclusive of developing countries’ scientists.
Science ‘under attack’ from fossil fuel interests at UN climate talks
The UK-Spanish statement weighed in less explicitly on this issue but said that they “recall the importance of scientific evidence and acknowledge the work of the IPCC in this respect.”
The British and French ministers said they would seek to accelerate reductions of emissions in methane, a particularly potent greenhouse gas, at COP31 in November. They encouraged governments “to work jointly to develop a marketplace for fossil fuels with near-zero methane intensity.”
Methane leaks from oil, gas and coal production are a major contributor to global warming. Over a 20-year period, methane traps around 80 times more heat than carbon dioxide.

The UK and Spanish statement emphasised the importance of supporting the Global South and underlined the need to mobilise sustainable financing “at scale with the challenge we face”. The previous UK government, in which Miliband was energy minister, cut climate finance to developing countries to pay for increases in military spending.
The UK government led by new Prime Minister Andy Burnham has yet to outline any major changes to climate finance in its two weeks in power but has announced it will convert some finance from grants to loans in order to free up money to subsidise bus travel in England.
More adaptation needed
Guterres said that “it is time to stop treating each disaster as an isolated tragedy and recognise the systemic risk that is unfolding before our eyes.” A recent study found that three-quarters of UK media reports about the British June heatwave did not mention climate change.
As well as reducing emissions, the UN Secretary-General called for measures to adapt vulnerable people to extreme heat. Specifically, he said that buildings should be built and retrofitted for extreme heat and that every city and country should have heat-health action plans and early warning systems. Over 250 cities have joined the UN’s ‘beat the heat’ initiative, he said.
The Portuguese diplomat called for governments and employers to do more to protect their workers from heat, criticising global fashion brands for not setting heat standards for the factories that supply them. “No one should have to risk their life to earn a living,” he said.
