Australia: Minister for Climate Change and Minister Chris Bowen says that the government is ‘considering’ the enactment of a Carbon Border Adjustment Mechanism (CBAM) to prevent carbon leakage from high emissions-intensity products, including cement.
The Australian Parliament committed to 43% national CO2 emissions reduction between 2005 and 2030 in 2022, and capped emitters’ individual carbon footprints in 2023. Final advice from a government Carbon Leakage Review was due after May 2025, and was possibly complicated by on-going US climate and trade reforms under President Trump. The Australian Cement Industry Federation bemoaned a lack of action on carbon leakage in March 2025. It warned of jeopardy to both decarbonisation and 1400 jobs in the Australian cement sector.
Australia’s construction industry imported 40% of its cement used in 2024.
Decarbonising in the US
04 June 2025A week ago, there were two fully-financed cement plant carbon capture, utilisation and storage (CCUS) projects underway in the US.1 Now, there aren’t.
Projects to decarbonise National Cement Company’s Lebec, California, plant and Heidelberg Materials North America’s Mitchell, Indiana, plant were each set to receive up to US$500m in US Department of Energy (DoE) funding on a one-for-one basis with private investments. The projects were to include eventual 950,000t/yr (Lebec) and 2Mt/yr (Mitchell) carbon capture installations. Additionally, the Lebec plant was to transition to limestone calcined clay cement (LC3) production and the use of alternative fuels (AF), including pistachio shells. Both were beneficiaries of the DoE’s US$6bn Industrial Demonstrations Program (IDP), touted by former US Secretary of Energy Jennifer Granholm as ‘Spurring on the next generation of decarbonisation technologies in key industries [to] keep America the most competitive nation on Earth.’ Disbursement of funding under the programme was frozen by executive order of President Trump in January 2025.2, 3
On 30 May 2025, Trump’s Secretary of Energy announced that the government in which Granholm served had approved spending on industrial decarbonisation without a ‘thorough financial review.’ He cancelled remaining project funding in signature Trumpian style, in list form.4 Among 24 de-funded projects, Lebec and Mitchell accounted for US$1bn (27%) of a total US$3.73bn in allocated funds that have now been withdrawn.
It's hard not to feel sorry for the management of the Lebec and Mitchell plant and the teams that had been working to deliver these projects. Heidelberg Materials has yet to comment, though CEO Dominik von Achten was in North America in late May 2025. National Cement Company parent Vicat, meanwhile, conceded the setback with a strong statement of its commitment to CO2 reduction, to 497kg/t of cementitious product globally.5 There was a diplomatic edge to the statement too, however. Echoing the Secretary of Energy, Vicat said that its target remains ‘solely based on existing proven technologies, including energy efficiency, AF substitution and clinker rate reduction’ – as opposed to ‘any technological breakthroughs’ like carbon capture. There are currently no public details of possible back-up financing arrangements for these projects; for now, the best guess at their status is ‘uncertain.’
Alongside these group’s local subsidiaries, another organisation that has to do business daily with the DoE is the American Cement Association (ACA). President and CEO Mike Ireland has continually acknowledged the complex needs of the government, while stating the association’s case for keeping support in place. With regard to these funding cuts, Ireland’s emphasis fell on the latter side: “Today’s announcement is candidly a missed opportunity for both America’s cement manufacturers and this administration, as CCS projects have long been supported by bipartisan members in Congress and bipartisan administrations.”6 He reasserted the ACA’s understanding that carbon capture aligns with the administration’s strategy to bolster domestic manufacturing and innovation.
The early 2020s heyday of US carbon capture was founded on gradual, consensus-based politics – unlike its demise. Table 1 (below) gives a non-exhaustive account of recent and on-going front-end engineering design (FEED) studies and the funding they received:

Additionally, MTR Carbon Capture, which is executing a carbon capture pilot at St Marys Cement’s Charlevoix plant in Michigan, previously received US$1.5m in Fossil Energy Research and Development funding towards a total US$3.7m for an unspecified cement plant carbon capture study.10
Market researcher Greenlight Insights valued industrial decarbonisation initiatives under the Office of Clean Energy Demonstrations (ODEC – the now defunct DoE office responsible, among other things, for the IDP) at US$65.9bn in cumulative returns in April 2025.11 The government has yet to publish any account of how it might replace this growth, or the 291,000 anticipated new jobs that would have come with it. Given all this (along with the extensive financial and technical submissions that accompanied each project), the issues raised by the DoE are presumably budgetary, or else founded in a perception of CCUS as essentially uneconomical.
Carbon capture is very, very expensive. A fatuous reply is that so is climate change, just with a few more ‘verys.’ Hurricane Ian in September 2022 cost US$120bn, more than enough to fund carbon capture installations at all 91 US cement plants, along the lines of the former Lebac and Mitchell agreements.12 Unlike climate change, however, carbon capture remains unproven. Advocates need to continually justify taxpayer involvement in such a high-risk venture.
At its Redding cement plant in California, Lehigh Hanson successfully delivered a funding-free FEED study, with its partner Fortera raising US$85m in a Series C funding. This presents an alternative vision of innovation as fully-privatised, in which the government might still have the role of shaping demand. This is borne out in the IMPACT Act, a bill which ‘sailed through’ the lower legislature in March 2025.13 If enacted, it will empower state and municipal transport departments to pledge to buy future outputs of nascent reduced-CO2 cements and concretes.
A separate aspect of the funding cancellation that appears decidedly cruel is the targeted removal of grants to start-ups. Two alternative building materials developers – Brimstone and Sublime Systems – were listed for a combined US$276m of now vapourised liquidity. Both are commercially viable without the funding, but the effect of this reversal – including on the next generation of US innovators who hoped to follow in their footsteps – can only be chilling. As non-governmental organisation Industrious Labs said of the anticipated closure of the ODEC in April 2025: “We may see companies based in other geographies start to pull ahead.”
Heidelberg Materials’s Brevik carbon capture plant came online in June 2025, 54 months after the producer secured approval for the project. The term of a presidency is 48 months. This probably means that producers in the US will no longer see CCUS as a viable investment, even under sympathetic administrations.
Even as government funding for CCS flickers from ‘dormant’ to ‘extinct,’ the sun is rising on other US projects. Monarch Cement Company commissioned a 20MW solar power plant at its Humboldt cement plant in Kansas on 27 May 2025. The global momentum is behind decarbonisation, even if economics determines that it will only take the form of smaller-scale mitigation measures at US cement plants into the medium-term future. We can hope that these, at least, might include the AF and LC3 aspects of National Cement Company’s plans at Lebec.

US: The Trump administration has cancelled a US$500m grant awarded in December 2024 to National Cement in California for the conversion of its Lebec cement plant into the state’s first net-zero cement facility. The project, valued at US$891m, aimed to switch to limestone calcined clay cement and use agricultural waste as fuel, with CO₂ captured for permanent underground storage, according to the Bakersfield Californian newspaper. It was expected to create 20 - 25 permanent jobs. The US Department of Energy (DOE) said the project was among 24 grants worth US$3.7bn cancelled due to failure “to advance the energy needs of the American people,” and cited economic infeasibility and poor return on taxpayer investment.
US Secretary of Energy Chris Wright said that the previous administration “failed to conduct a thorough financial review before signing away billions of taxpayer dollars.”
Executive director Steven Nadel of the American Council for an Energy-Efficient Economy said “Choosing to cancel these awards is shortsighted, and I think we're going to look back at this moment with regret.”
The project was one of 33 cement, steel and aluminium decarbonisation projects awarded DOE grants in 2023. The project turned up on an April 2025 list of 39 projects the DOE's Office of Clean Energy Demonstrations was considering terminating.
Greece: Holcim has broken ground at the Olympus project at its Milaki plant, which will produce 2Mt/yr of ‘near-zero-CO2’ cement from 2029. The producer will invest €400m in the development, and it has secured €125m from the EU Innovation Fund. The plant will combine OxyCalciner and Cryocap FG technologies for carbon capture. Holcim said the project would create over 1000 jobs for the local area.
Holcim CEO Miljan Gutovic said “The Olympus project in Greece is one of our seven large-scale, EU-supported carbon capture, utilisation and storage projects that are setting the Clean Industrial Deal in motion. Together, these will enable Holcim to offer over 8Mt/yr of near-zero cement across Europe by 2030.”
UAE: Emsteel has signed a strategic partnership with Finnish company Magsort to produce decarbonised cement using steel slag. The agreement follows an industrial-scale pilot at its Al Ain plant that used 10,000t of steel slag to produce low-carbon cement. To meet growing local demand, Emsteel will build an integrated line at the Al Ain facility to process steel residue from its Abu Dhabi steel plant.
Heidelberg Materials signs CCS MoU with Arup
27 May 2025Europe: Heidelberg Materials and environment consultancy Arup have signed a memorandum of understanding (MoU) to collaborate on decarbonisation of the built environment through carbon capture and storage-enabled cement and concrete.
The partners will conduct joint research and technical analysis on the deployment of CCS technologies across cement and concrete production. Heidelberg Materials and Arup previously began collaborating in November 2024 to assess the benefits and feasibility of carbon-captured cement and concrete.
UAE: Manufacturing conglomerate Exeed Industries has signed a memorandum of understanding with sustainable building materials producer Partanna Oasis to explore local production of carbon-negative cement alternatives in the UAE. Both parties will plan to establish a brine conversion facility, a tolling facility and a cement plant to commercialise Partanna’s products in the UAE. The two companies will collaborate on certification, performance testing and regulatory alignment.
India: The Department of Science and Technology (DST) has launched five carbon capture and utilisation (CCU) testbeds in the cement sector, forming a research and innovation cluster to help accelerate industrial decarbonisation. The five testbeds are collaborative industrial pilot projects between Indian research institutions and local cement manufacturers under a public-private partnership model. The testbeds aim to help India reach carbon neutrality by 2070.
Each testbed targets a specific CCU approach. Testbed 1, in partnership with JK Cement in Ballabhgarh, will be a pilot plant capable of capturing 2t/day of CO₂ and converting it into lightweight blocks and olefins through oxygen calcination. Testbed 2, by IIT Kanpur and JSW Cement, will explore CO₂ mineralisation. Testbed-3, with IIT Bombay and Dalmia Cement, will develop catalyst-based capture at a cement plant. Testbed-4, by CSIR-IIP, IIT Tirupati, IISc and JSW Cement, will use vacuum swing adsorption technology. Testbed-5, with IIT Madras, BITS Pilani Goa and UltraTech Cement, will focus on carbon-lowering process innovations.
Germany: Heidelberg Materials increased its revenue by 5% year-on-year to €4.71bn in the first quarter of 2025. Operating earnings from current operations rose slightly to €235m from €232m in the previous year.
“Despite the political and economic uncertainties as well as difficult weather conditions in some regions, we got off to a very good start to the 2025 financial year,” chair Dominik von Achten said. “In particular, we benefitted from significant growth in the Africa-Mediterranean-Western Asia group area.”
He added “In the first three months of 2025, we continued to set the course for our sustainable transformation. Final preparations for our CCS lighthouse project in Brevik, Norway, are currently well underway. We started capturing, liquefying and temporarily storing CO₂ a few days ago as part of the plant's ramp-up. We look forward to the grand opening of the world's first large-scale industrial carbon capture facility at a cement plant in June.”
The company confirmed its outlook for the 2025 financial year. It expects full-year earnings of €3.25bn – €3.55bn.
US: Queens Carbon has secured US$10m in seed funding to scale up production of its novel cement and supplementary cementitious materials (SCMs). The start-up will build a 2000t/yr demonstration plant at strategic partner Buzzi Unicem USA's Stockertown, Pennsylvania, cement plant. The plant will demonstrate Queens Carbon’s low-energy Q-Reactor technology, which employs novel hydrothermal chemistry, with the help of steam and pressure, to combine standard cement feedstocks into carbon-neutral hydraulic cement and SCMs. The company’s flagship product, Q-SCM, is capable of replacing up to 50% of cement in concrete mixes. Queens Carbon says that it will now also begin preparations for its first full-scale commercial plant.
Buzzi Unicem USA was among investors in the seed funding round, led by Climate technologies investor Clean Energy Ventures, with participation from fellow venture capital firm Plug and Play.
Queens Carbon CEO Daniel Kopp said "With support from Clean Energy Ventures, Buzzi Unicem USA and the US Department of Energy, we're building next-generation technology and assembling the creative talent needed to drive industry revenues to move cement innovation forward and significantly reduce CO2 emissions from cement production, all without a green premium."
Luigi Buzzi, Chief Technology Officer at Italy-based Buzzi, said "We know that achieving our goal of net-zero carbon emissions by 2050 demands forward-thinking solutions to enhance both our operations and our environmental performance.”
