Key developments
Food ‘catastrophe’
FAO WARNING: On Monday, the UN Food and Agriculture Organization (FAO) warned that a prolonged closure of the strait of Hormuz could lead to a “global food catastrophe”, reported Al Jazeera. With 20-45% of the world’s key agrifood inputs dependent on the sea passage, the outlet explained, poorer countries would be the “most exposed”, with delays in accessing fertilisers “quickly translating into lower output”. A Financial Times essay detailed how the Gulf region has come to “sit at the centre of modern agriculture” over the past two decades”.

‘PERFECT STORM’: The FAO also warned countries to “not limit shipments” of energy and fertilisers, warning that such restrictions have led to food price spikes in the past, wrote Bloomberg. The UN body asked countries to “closely ponder” biofuel mandates, given the choice between high oil prices and curtailing global food supplies. In a statement, FAO chief economist Dr Maximo Torero warned of a “perfect storm”, if the world is also affected by a strong El Niño.
COUNTRIES RESPOND: Sri Lanka, already “burdened with old fertiliser debts”, has promised to provide fertiliser subsidies to farmers, reported Sri Lanka’s Sunday Times. In India, “fear of a fertiliser shortage is particularly heightened”, wrote Scroll.in. In Australia – where 60% of urea comes from the Persian Gulf – the war could herald a fertiliser “manufacturing comeback”, reported ABC News. Reuters looked at how China is “clamping down on fertiliser exports to protect its domestic market”.
Study: Wood vs gas burning
BASHING BECCS: A new study found that “bioenergy with carbon capture and storage (BECCS) is unlikely to generate negative emissions within 150 years”. The paper added that BECCS is likely to “produce higher emissions for decades than using natural gas without carbon capture” and to “increase electricity costs by ~3.5-fold”. The Guardian covered the research, stating that its findings “cast doubt” on government plans to offer subsidies for carbon capture attached to wood-burning power, such as the UK’s Drax power station.
INTERPRET WITH CAUTION: Prof Joana Portugal Pereira, an assistant professor at the Federal University of Rio de Janeiro, told Carbon Brief that the study is “clearly framed and the modelling approach is transparent”. However, she said the results are “very sensitive to the assumptions made” and advised “caution” in drawing conclusions from the analysis. For example, she noted that the study “focuses on BECCS supplied from existing forests”, which is likely to “emphasise higher emissions outcomes”.
MISLEADING HEADLINE: Dr Isabela Butnar, a lecturer in environmental policy at University College London, praised parts of the methodology and agreed that “forest-based BECCS for electricity is a no-go”. However, she argued that the title of the paper – “Decades of increased emissions from forest-fuelled BECCS” – might be “a bit misleading”. The title should specify that the analysis only applies to BECCS for electricity production, she said.
News and views
- TOO HOT TO FARM: A major new joint report by the FAO and the World Meteorological Organization estimated that extreme heat “currently threatens” the livelihoods of more than 1 billion people, with agricultural workers on the “frontlines…absorbing the greatest impacts”. Farmers in much of south Asia, sub-Saharan Africa and central and South America could find it “simply too hot to work” for up to 250 days a year, the report cautioned.
- PALM READING: Demand for palm oil has “surged as the war in Iran drives countries to build up stockpiles” and “boost” biofuel programmes in response to higher crude oil prices, reported Nikkei Asia. While Malaysian and Indonesian palm oil exports have risen to their “highest level in months”, longer-term supply could be “threatened” by rising fertiliser prices and “high temperatures caused by climate change”, added the outlet.
- RED LIST: Emperor penguins and the Antarctic fur seal “have joined the list of wildlife endangered by global warming”, according to the International Union for Conservation of Nature’s (IUCN) Red List, reported the New York Times. Conversely, “iconic” blue-and-yellow macaws have returned to Rio de Janeiro after a 200-year absence, following an ambitious “refaunation” programme, wrote the Guardian.
- CATTLE CLASS: A new Unearthed investigation found that a major US biofuels producer supplied the UK with “sustainable aviation fuel” derived from “beef fat linked to illegal Amazon deforestation”. Darling Ingredients – the producer’s parent company – denied sourcing tallow from slaughterhouses sourcing cattle from illegal farms in the Amazon. It told the outlet it was “in the process” of requiring suppliers to prove their products were “deforestation-free”.
- FUND OPEN: On 10 April, Ecuador issued its “first call” for grants to protect 1.8m hectares of the Ecuadorian Amazon using the $460m Amazon Biocorridor Fund, reported EFE Verde. The trust fund is linked to what is considered the “largest debt-for-land nature swap”, added the outlet. [For more on debt-for-nature swaps, see Carbon Brief’s 2024 explainer.]
- SUPER EL NIÑO: Scientists expect a strong El Niño event to develop by early autumn, driving up global temperatures, according to Carbon Brief’s latest state of the climate update. The analysis said that if a super El Niño develops this year, it is likely that 2027 will top the charts as the hottest year on record. It added that “the latest climate models give a central estimate of 2.2C warming by September – a scenario which would put the world firmly in ‘super’ El Niño territory”.

Oxford solar farm under fire
This week, Carbon Brief unpacks what the UK’s Botley West solar farm development would mean for farmland and biodiversity in the area.
Planning permission for one of Europe’s largest solar farms has been delayed, after the UK government asked for more time to consider the proposal from the developer.
Oxfordshire’s Botley West solar farm has been under consultation since 2022.
If approved, the site – located 80km north-west of London – will deliver 840m watts (MW) to the UK power grid.
However, the development faces vehement opposition – most notably from the Stop Botley West campaign group, which has said the “vast” solar farm will have “unprecedented” visual impact, drive the loss of “arable farmland” and will “disregard Oxford’s green belt”.
Politicians frequently use solar farms to score points with their supporters, with some MPs describing the developments as hazards for rural communities and food supply.
Farmland loss
Most of the land earmarked for the solar farm belongs to the Blenheim estate – a 12,000-acre expanse surrounding the UNESCO world heritage site of Blenheim Palace.
Dr Jonathan Scurlock – the former chief climate adviser at the National Farmers’ Union, which represents farmers in England and Wales – told Carbon Brief that the estate rents out much of its land to tenant farmers. However, he added, it is “not terribly good quality farmland”.
The UK government has a ranking system for agricultural land that is being considered for large-scale development projects, where five indicates “very poor quality” and one indicates “excellent quality”. Developers are generally encouraged to build on lower-quality land, leaving the high-quality land for farming.
According to the Botley West website, 62% of the land surveyed for the proposed solar farm is agricultural grade 3b – defined as “moderate-quality agricultural land”. The remainder is mostly 3a, defined as “good-quality agricultural land”.
Many opponents of Botley West argue that the farm will take away vital farmland. However, Scurlock said:
“Solar is perceived as very challenging to land use and yet the evidence nationally really doesn’t support that…Solar farms do not really represent lots of agricultural land capacity”.
(A 2025 Carbon Brief factcheck found that golf courses currently take up six times as much land in the UK as solar farms.)
The developers plan for the solar panels to remain on-site for about 40 years, after which the fields will be returned to use for agriculture.
Biodiversity gain
The proposed solar farm has also promised to improve local biodiversity.
New development projects in the UK must deliver a “biodiversity net gain” (BNG) under a 2024 regulation.
Developers must arrange for the “biodiversity value” of the land to be assessed, considering factors including the size, quality, location and type of each habitat. They must then ensure that the final project increases this value by at least 10%.
If the Botley West project is approved, the developers will aim for 70% BNG.
Prof Alona Armstrong, an energy researcher from Lancaster University, told Carbon Brief that around two-thirds of solar farms in the UK are built on “ex-arable lands”.
She explained that biodiversity outcomes on solar farms depend on where the farms are located and how they are designed and managed. Much agricultural land is “intensively managed”, with the use of chemicals and farming machinery. In contrast, there is less chemical and machinery use on solar farms, potentially benefiting biodiversity.
Armstrong added that solar farms are often lined with hedges, which are “really good for biodiversity”, acting as refuges for a wide range of plant and animal species.
The latest BNG statement for Botley West filed with the government featured a “habitat and hedgerows creation and enhancement plan”.
The plan included creating 26.5km of new species-rich hedgerow, enhancing 25km of existing hedgerows and developing a range of grassland types within the solar arrays to be managed for conservation.

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.
