Japan: The Renewable Energy Institute (REI) has published The Decarbonisation Pathway for Japan's Cement Industry, a report on strategies to ensure cement industry decarbonisation in line with a global 1.5°C climate change limit. The report found that the calcination of limestone gives rise to 60% of process CO₂ emissions from Japanese cement production. The report reviews possibilities for tackling emissions both from calcination and from other sources. In the former category, it noted scope for clinker factor reduction. Japan Cement Association members recorded an average clinker factor of 0.8 and Scope 1 emissions of 680kg/t of cementitious product in 2024. REI contrasted this with India-based Dalmia Bharat, which had a clinker factor of 0.6 and Scope 1 emissions of 467kg/t.

Belgium: Etex and Heidelberg Materials have joined forces on CEMLOOP XL, an industrial-scale project co-funded by the EU’s LIFE Programme that aims to revolutionise fibre cement recycling through a fully closed-loop process integrating carbon capture utilisation and storage (CCUS) technology. According to a press release by Etex, this will reduce CO₂ emissions in cement production by at least 20% and cut energy consumption in the process by 15%.

The project will combine the two companies' expertise to create a fully circular process where waste fibre cement is transformed into high-quality secondary raw material to produce low-carbon cement that will be reused in new fibre cement products. Etex, in collaboration with the Jacobs Group, is developing a recycled fibre cement paste (RFCP) process that converts waste from Etex’s production lines and the wider construction sector into reusable material and avoids landfilling. A new recycling facility in Hemiksem, near Antwerp, is under construction and scheduled for completion by mid-2026.

At Heidelberg Materials’ Lixhe cement plant in Liège, the company is implementing CCLIX, a carbonation process that treats RFCP with CO₂ captured from kiln exhaust gases. This produces carbonated RFCP (cRFCP), which regains cementitious properties and can partially replace clinker in low-carbon cement production. A dedicated carbonation reactor is set to be commissioned at Lixhe by the end of 2028.

Etex says that CEMLOOP XL will prevent 60,000t/yr of fibre cement waste, save 100,000t/yr  of raw limestone, and capture or avoid around 900kg of CO₂ for each tonne of RFCP produced. This process combines utilisation and storage in one step - the captured CO₂ becomes chemically bound within the new product, acting as a permanent CO₂ sink.

Eric Bertrand, chief innovation officer at Etex, said “By 2030, we aim for over 20% of our inputs to come from circular sources and to send zero waste to landfill. Fibre cement plays a central role in this transformation. For the first time, it will follow a fully circular journey - a milestone only made possible through strong partnerships like this with Heidelberg Materials.”

Germany: Economy Minister Katherina Reiche has announced a €6bn industrial decarbonisation initiative that, for the first time, includes carbon capture and storage (CCS) technologies within the country’s climate protection contracts. The programme targets energy-intensive industries such as cement, as Germany navigates stringent climate targets amid concerns over industrial competitiveness. Companies have until 1 December 2025 to register projects for next year’s bidding round, which is scheduled to begin in mid-2026, pending parliamentary budget approval and EU state aid clearance, according to Reuters.

Under 15-year contracts, the government will subsidise part of the cost for companies transitioning to low-carbon production, protecting them from energy and carbon price volatility. Contracts will be awarded through competitive auctions, prioritising projects with the lowest subsidy per tonne of CO₂ saved, alongside binding emission-reduction milestones. Industry groups have welcomed the inclusion of CCS and the flexible contract design, describing the programme as a pragmatic step toward reconciling climate objectives with the economic pressures facing German industry.

India: The government has notified the Greenhouse Gases Emission Intensity Target Rules, 2025, establishing legally binding reduction targets for 282 industrial units in cement and other heavy industries. The notification was issued by the Ministry of Environment on 8 October 2025 after considering all suggestions and objections received on the draft rules, which were published on 16 April 2025. Facilities must reduce greenhouse gas emissions per tonne of output from 2023–24 baseline levels during the 2025–26 to 2026–27 compliance period.

The rules implement the Energy Conservation (Amendment) Act, 2022, which supports the creation of a domestic carbon market. Plants emitting below the target will earn tradable credits; those exceeding limits must buy credits or pay a penalty equal to twice the average credit price. The average price will be determined by the Bureau of Energy Efficiency (BEE). The Central Pollution Control Board (CPCB) will impose and oversee recovery of penalties, which must be paid within 90 days. Major cement producers including UltraTech, Dalmia, JK Cement, Shree Cement and ACC are included, with reduction targets of up to 3.4% over two years. The framework supports India’s Paris Agreement commitments and prepares exporters for mechanisms such as the EU Carbon Border Adjustment Mechanism.

Germany: Rohrdorfer has inaugurated a new pilot plant for tempered clays at its Rohrdorf cement facility in a ceremony attended by regional and state officials. They included Parliamentary State Secretary to the Federal Ministry of the Interior Daniela Ludwig, who cut the ribbon alongside Rohrdorfer managing director Mike Edelmann.

The pilot plant has been operational since July 2025 and activates up to 50t/day of raw clay through thermal treatment. Tempered clays can replace clinker in cement, reportedly helping to cut emissions by around 30%, according to the company. The project is funded by the Federal Ministry for Economic Affairs and Climate Protection and the EU, and will receive up to €8.65m in funding.

Daniela Ludwig said “With this new plant, the Rohrdorf cement plant is once again proving that it is one of the most innovative companies in our region. Decarbonising the cement industry is a key task if Germany is to achieve its climate goals as planned.”

By the end of 2026, Rohrdorfer’s Net Zero Emission team will determine the optimal composition of raw clays and refine the thermal treatment process, paving the way for a large-scale facility capable of achieving up to 60% CO₂ reductions.

Mike Edelmann said “We’ve achieved a lot within our plants, but our influence ends at the factory gates. The lack of planning security regarding CO₂ transport and storage, uncompetitive electricity prices and an uncertain mining landscape are holding us back. We urgently need more support from policymakers if climate targets are to be met.”

Bulgaria: Zlatna Panega Cement, part of Greece-based Titan Group, has achieved a 65% rate of thermal substitution of fossil fuels with alternative fuels for four consecutive months. The company’s 5MW solar plant supplies between 11% and 13% of its energy needs.

General director Adamantios Francis said “We have achieved a historic success for our plant. With this, we prove that we are committed to sustainable development and are ready to lead the industry towards a greener future.”

Titan Group’s long-term strategy includes cutting energy consumption by 58% compared with 2020 levels and reducing direct net CO₂ emissions to 500kg/t of cement. At Zlatna Panega, CO₂ emissions in 2024 were 839kg/t of clinker, while electricity-related emissions fell by 38% year-on-year.

Kenya: Equator Energy has commissioned a 10MW captive solar power plant at Mombasa Cement’s Vipingo facility in Kilifi County. The new installation will reduce the producer’s reliance on the national grid, reduce CO₂ emissions and deliver ‘substantial’ cost savings, according to Equator Energy’s post on LinkedIn. During construction, around 100 temporary jobs were created, while 15 permanent roles have been established to support ongoing operations. The project was implemented under a power purchase agreement (PPA) and is part of broader efforts to boost renewable energy adoption in Kenya’s industrial sector.

UK: Heidelberg Materials has reached a Final Investment Decision (FID) with the UK Government for its carbon capture and storage (CCS) project at the Padeswood cement works in north Wales, clearing the way for construction to begin later in 2025.

Energy Minister Michael Shanks announced the decision today, which will enable Heidelberg Materials to produce net-zero cement by 2029. The project will capture around 0.8Mt/yr of CO₂, approximately 95% of emissions from the cement works, and transport them via pipeline for storage under Liverpool Bay as part of the HyNet North West project.

Simon Willis, CEO of Heidelberg Materials UK, said “Our constructive partnership with the UK Government has allowed us to reach this major milestone, which is fantastic news, not just for us, but for the industry as a whole. Our new facility at Padeswood will be a world-leader. It will allow us to produce evoZero carbon captured net zero cement, which will help the UK construction industry reach its decarbonisation aims.”

The project is expected to create 50 new jobs, and generate up to 500 more during construction. It is the UK’s first full-scale CCS project for cement and follows Heidelberg Materials’ recent success in Norway, where it launched the world’s first carbon capture facility at its Brevik cement plant in June 2025. Here, 50% of the plant’s emissions are being captured as part of the Norwegian government’s Longship programme.

The UK-based Mineral Products Association (MPA) has celebrated this step, with Dr Diana Casey, Executive Director for Energy and Climate Change, Cement and Lime, saying “The green light for the UK’s first carbon capture-enabled cement plant at Padeswood is a landmark step on the road to decarbonising our domestic cement industry – it will safeguard existing skilled jobs and create new opportunities too. Public investment in this project provides a strong vote of confidence in the technology and recognises the vital role cement plays in supporting economic growth while delivering on the transition to net zero. Decarbonising heavy industry is not only essential for meeting climate goals, but also for securing the future of communities across the country – today’s announcement delivers on both.”

Japan: Mitsubishi UBE Cement Corporation (MUCC), Osaka Gas, Daigas Energy and Saibu Gas have successfully tested natural gas co-firing at MUCC’s Kyushu Plant in the Kurosaki area. Using a newly developed burner, the companies replaced 40% of coal with natural gas at commercial scale without affecting kiln stability, product quality or environmental performance.

The burner was developed using MUCC’s coal combustion expertise alongside Osaka Gas and Daigas Energy’s gas combustion and simulation technologies, with Saibu Gas supplying natural gas from LNG tank trucks. MUCC said the trial paves the way for full-scale implementation and supports future use of e-methane in cement kilns.

MUCC aims to cut CO₂ emissions by 40% by 2030, compared to 2013 levels, and achieve group-wide carbon neutrality by 2050 under its medium-term management strategy “Infinity with Will 2025 – MUCC Sustainable Plan 1st STEP.”

US: Supplementary cementitious materials (SCM) producer Eco Material Technologies has published its 2024 Sustainability Report, detailing the measures it has employed to reduce its environmental impact over the year. The producer said that its SCM displaced 5% of US cement consumption, avoiding 5.5Mt of CO₂ emissions. The company diverted 6.2Mt of ash from landfill and harvested a further 0.5Mt, reducing water use by 7.57bn litres compared to conventional materials. It produced 73,292t of ‘green’ cement, avoiding over 65,000t of CO₂, and aims to double recycled material use to 20Mt by 2030.

Chief executive officer Grant Quasha said “We're proving that domestic fly ash is not only a powerful climate solution, but also a resilient and scalable one. The infrastructure transformation is already underway, and we're proud to be leading it.”

Eco Material Technologies operates 125 sites in 42 states and employs 1100 people.
