The bulk of steelmaking around the world still relies on coal-based blast furnaces.
As a result, the steel and iron industry is responsible for 7% of greenhouse gas emissions and 11% of carbon dioxide emissions globally, according to the consultancy firm Global Efficiency Intelligence.
This is more than the total emissions from all the world’s cars and vans.
With steel critical to the building out of decarbonised energy infrastructure, production is expected to continue to rise over the coming years, meaning the potential for decarbonisation is “enormous”, according to not-for-profit data organisation Global Energy Monitor (GEM).
GEM’s annual “Pedal to the Metal” report reveals that 93% of new steelmaking capacity announced thus far in 2024 promises to use lower emission electric arc furnaces (EAFs).
It also shows that 49% of the world’s steelmaking capacity under development now uses EAFs, up from just 43% in 2023 and 33% in 2022.
Of this, nearly all of the capacity announced since the beginning of 2024 operates using EAFs, the non-governmental organisation’s Global Steel Plant Tracker (GSPT) shows.
The tracker covers 2,207m tonnes per year (mtpa) of operating steelmaking capacity and an additional 774mtpa of steelmaking capacity under development globally, across 1,163 individual plants in 89 different countries, analysis of which is captured in its annual report.
However, while the report suggests a positive progression towards lower emission technologies in the sector, the increase in the announced projects is not yet leading to a construction of EAF overtaking coal-based production methods.
Coal-based blast furnace-basic oxygen furnaces (BF-BOFs) – where blast furnaces are used to produce iron from ore and oxygen converters then turn this, with some additional elements, into steel – continue to dominate the projects under construction, meaning “pressure must be maintained all the way through to project completion if real progress is to be seen”, the report finds.
Growth of EAFs
Incoming steelmaking capacity is more heavily EAF-based than ever before, according to GEM’s new report.
There is currently 774mtpa of steelmaking capacity under development, of which 223mtpa is in the advanced development stage.
Based on data from April 2024, the GSPT shows that nearly half of the capacity under development (337mtpa) is EAFs.
Just 36% of steelmaking capacity announced in 2020 with a known production route used EAFs, while in 2023 that number had increased to 92% according to GEM. This grows to 93% of capacity when looking at steelmaking capacity under development announced in 2024.
This “indicates a significant shift toward electric arc furnace steelmaking in the years to come”, the report notes.
Meanwhile, of the 212mtpa of steelmaking capacity slated for retirement, 88% if BOF-based.
However, a net increase in BOF-based capacity is expected over the coming years. If all planned developments and retirements take effect, an additional 171mptpa of BOFs is expected to be added to the global fleet, along with 310mtpa of EAF and 80mtpa of unknown technologies.
Despite this growth in BOFs, the surge of EAF means the steel sector is getting increasingly close to meeting the International Energy Agency’s (IEA) suggested 2030 target.
In its net-zero by 2050 roadmap, the IEA suggests that the share of steel produced by EAF should grow from 24% in 2020, to 37% by 2030 and then 52% by 2050.
Considering all planned capacity and retirements, GEM now estimates that the global steel fleet is expected to reach 36% EAF by 2030, noting: “This is still not sufficient to meet the IEA [net-zero] climate target, but with heightened momentum the goal is increasingly attainable.”
Continuing to construction
While EAF-steelmaking is being announced at “record rate”, GEM finds that less than 14% of this potential capacity has moved into construction.
Of those that have moved into construction, around 46% are still BOF-based. As such, “while we may be within reach of net-zero targets based on proposed electric arc furnace capacity, actually achieving these goals requires follow-through”, the report notes.
Caitlin Swalec, program director for heavy industry at GEM, said in a statement:
“The progress is promising for a green steel transition. Never before has this much lower-emissions steelmaking been in the pipeline. At the same time, the buildout of coal-based capacity is concerning. What the industry needs now is to make these clean development plans a reality, while backing away from coal-based developments.”
As well as the buildout of new coal-based capacity being out of alignment with a net-zero future, it poses a threat of carbon lock-in and stranded assets, GEM notes.
Blast furnaces are becoming riskier investments given the limited options to mitigate emissions from both the furnaces themselves and the upstream emissions from the metallurgical coal mining, it adds.
Estimating an investment of $1-1.5bn per mtpa capacity at an integrated BF-BOF site, GEM found that the future stranded-asset risk could be as high as $554bn in 2023, falling to $400bn in 2024 due to the continued fall in BOF capacity under development.
Astrid Grigsby-Schulte, project manager for steel at GEM tells Carbon Brief:
“As we grow closer to key decarbonisation milestones, coal-based developments get further out of alignment with the direction the industry is moving and present a greater risk of stranded assets to steelmakers. Coal-based, emissions-intensive blast furnaces represent significant investments that often require decades to recoup. This makes them extremely risky for developers, particularly in countries with stated net zero commitments.”
The limited options for mitigating the climate impact of BOF-steelmaking was also highlighted within a recent report from the thinktank Sandbag.
While carbon capture, utilisation and storage (CCUS) is often touted as a “catch all” solution, its effectiveness varies widely across applications, Sandbag’s “Steel & CCS/U” report finds.
For steel production, BF-BOFs with carbon capture are unlikely to be cost-competitive with EAFs, the report finds. Although given the slow pace of technological and market development, Sandbag anticipates capturing carbon will play a limited role in the steel industry.
China transitions to EAFs
India has now replaced China as the top steel developer globally, with a pipeline of 258mtpa of capacity, of which 177mtpa is BOFs, according to GEM.
China has a pipeline of 150mtpa meaning, collectively, China and India are responsible for 53% of all developments globally.
Asia operates 68% of all steelmaking capacity (1,508mtpa), the majority of which is in China (1,075mtpa), India (123mtpa) and Japan (109mtpa).
When looking specifically at emissions-intensive BOF production, Asia’s share of total operating capacity increases to 80% (1,181mtpa), of which 918mtpa is in China.
Currently, China has 157mtpa of operating EAFs (22% of the global capacity), followed by the US, Turkey, Iran and then India.
According to a new report from the Centre for Research on Energy and Clean Air (CREA), China did not issue any new permits for coal-based steelmaking in the first half of 2023. This is the first time this has happened since the nation’s “dual carbon goals” were announced in September 2020.
During the first six months of 2024, Chinese provincial governments permitted 7.1mtpa of steelmaking capacity, all of which were EAFs marking a “turning point” for the country’s steel industry, CREA notes.
Xinyi Shen, researcher at CREA and the report’s lead author, tells Carbon Brief: :
“China’s EAF steelmaking has been developing rather slowly in the past few decades, mainly due to the constraint of scrap supply. However, as China’s steel demand reaches its peak and more scrap becomes available, a major opportunity arises to reduce emissions in the next 10 years. The government has accelerated plans to expand the national ETS to include the steel sector by the second half of 2024. By implementing carbon pricing on carbon-intensive products, EAF steelmaking would become more economically competitive and continue the growth.”
Despite India now overtaking China in terms of announced steelmaking capacity, China remains the biggest developer of EAF capacity overall, GEM’s report states. And while India has the most steel in development, 84% has not moved into construction.
As such, there is still an opportunity for India’s plans to change, with the percentage of BOFs to EAFs less set.
Chris Bataille, adjunct research fellow at the Columbia University Center on Global Energy Policy and lead author at the global Net Zero Steel project tells Carbon Brief:
“India’s core demand for steel is set to increase from 125mtpa to ~450mtpa by 2050, especially to meet key building and infrastructure needs. Our modelling suggests EAFs consistently rise from ~35 to 150mtpa by 2050. So the +250mtpa BF-BOFs is just barely feasible, but only over ~25 years and with some exports of BF-BOF steel.
“The difference will be between a world where strong climate policy succeeds and fails. If it fails and coal based BF-BOFs are built, then the +258mtpa looks barely feasible. If it succeeds, India is short on the necessary gas and especially clean electricity to power this amount of steel production. While the country does build a lot of EAFs, it builds up to 250mtpa of clean iron making over time, making the short term shortfall with clean HBI iron imports.”

Climate Activists Stage Mock Funeral for Landmark Climate Rule
Global oil demand is expected to be almost one million barrels per day less than was forecast before the Iran war, as shortages and soaring costs prompt drastic cutbacks by consumers and businesses, a report by the International Energy Agency (IEA) said on Wednesday.
With the closure of the Strait of Hormuz choking off supplies and keeping prices high, less oil is being used to make products such as jet fuel, LPG cooking gas and petrochemicals, the Paris-based IEA said in its monthly oil report, forecasting the biggest quarterly demand drop since the COVID pandemic.
The Iran war “upends our global outlook”, the government-backed agency said, adding that it now expects oil demand to shrink by 80,000 barrels per day in 2026 from last year.
Before the conflict began, the IEA said in February it expected oil demand to rise by 850,000 barrels per day this year, meaning the difference between the pre-war and current estimates is 930,000 barrels a day, or 340 million barrels a year.
That could have a significant impact on the outlook for planet-heating carbon emissions this year.
At an intensity of 434 kg of carbon dioxide per barrel of oil – the estimate used by the US Environmental Protection Agency – the annual reduction in carbon dioxide emissions from oil for 2026, compared with the pre-war forecast, is similar to the amount emitted by the Philippines each year.
Harry Benham, senior advisor at Carbon Tracker, told Climate Home News that he expects at least half of the reduction in oil demand to be permanent because of efficiency gains, behavioural change and faster electrification.
The oil shock is leading to oil being replaced, especially in transport, with electricity and other fuels, just as past oil shocks drove lasting reductions in consumption, he said. “The shock doesn’t delay the transition – it reinforces it,” he added.
Demand takes a hit
While demand for oil has fallen significantly, supplies have fallen even further. Supply in March was 10 million barrels a day less than February, the IEA said, calling it the “largest disruption in history”.
This forecast relies on the assumption that regular deliveries of oil and gas from the Middle East will resume by the middle of the year, the IEA said, although the prospects for this “remain unclear at this stage”.

Fossil Free Zones can be on-ramps to the clean energy transition
Oil and gas blocks overlap with a fifth of forests in the Amazon, Congo Basin and SE Asia – policies are needed to transition away from fossil fuels and halt deforestation together
Last month, US Energy Secretary Chris Wright told the CERAWeek oil industry conference that prices were not high enough to lead to permanent reductions in demand for oil, known as demand destruction.
But the IEA said on Wednesday that “demand destruction will spread as scarcity and higher prices persist”.
Industries contributing to weaker demand for oil include Asian petrochemical producers, who are cutting production as oil supplies dry up, the report said, while consumers are cutting back on liquefied petroleum gas (LPG), which is mainly used as a cooking gas in developing countries, the IEA said.
Flight cancellations caused by the war have dampened demand for oil-based jet fuel, the IEA said. As well as cancellations caused by risk from the conflict itself, airports have warned that fuel shortages could lead to disruption.
Across the world, governments, businesses and consumers have sought to reduce their oil use after the war. The government of Pakistan has cut the speed limit on its roads, so that people drive at a more fuel-efficient speed, and Laos has encouraged people to work from home to preserve scarce petrol and diesel.
Nepal’s EV revolution pays off as oil crisis causes pain at the pumps
Consumers in Bangladesh are seeking electric vehicles (EVs) to avoid fuel queues and, in Nigeria, more people are seeking to replace petrol and diesel generators with solar panels, Climate Home News has reported.
In the longer term, the European Union is considering cutting taxes on electricity to help it replace fossil fuels and France is promoting EVs and heat pumps.
IEA urged to help “future-proof” economies
Meanwhile, the IEA came under fire last week from energy security experts, including former military chiefs, who signed an open letter in which they accused the agency of offering “only a temporary response to turbulent markets”, calling for stronger structural action “to future-proof our economies”.
They said that besides releasing emergency oil stocks and offering advice on how to reduce oil demand in the short term, the IEA should show countries how to reduce their exposure to volatile oil and gas markets.
The IEA has also been under pressure from the Trump administration to talk less about the transition away from fossil fuels.
