India: During the fourth quarter of the 2025 financial year (which ended on 31 March 2025), premium products constituted 16% of Shree Cement’s sales mix, up from 12% one year previously. During the period, the company further diversified its offering with the launch of two new premium cements, Bangur Marble Portland slag cement and Extra White Portland slag cement, in Bihar, Jharkhand and West Bengal. Both products are designed for maximum brightness and smoothness within their category of CEM-II Portland slag cements. The company says that its growing portfolio helped it to increase its full-year financial realisation per tonne by 5% year-on-year.

Business Today News has reported that managing director Neeraj Akhoury said "In the 2025 financial year, 74% of our cement output was blended, avoiding over 7.2Mt of CO₂ emissions."

Shree Cement crossed 60% consumption of energy from renewable sources in May 2025, Construction World News has reported. It has 582MW of installed renewable power capacity and is currently in the process of building a 1MW battery storage system at one of its cement plants in India.

UK: Holcim UK will roll out Fuelre4m’s Re4mx fuel reforming technology across more than 200 sites nationwide, following three years of testing that the company says improved fuel efficiency and helped reduce emissions across operations.

Holcim UK supply chain director Edern Lalanne said “This agreement is the result of meticulous testing, collaboration and operational learning. We have seen consistent results with Re4mx across a wide range of use cases, and it aligns directly with our commitment to sustainable innovation and operational excellence. This is about measurable outcomes, not promises, and Fuelre4m has delivered both the data and the support to back it up. This is part of our mission to make sustainable construction a reality and continues our journey to achieve net-zero by 2050.”

Re4mx will be delivered in pre-measured containers and dosed directly into on-site fuel systems. Holcim says that the rollout has been designed for ease, speed and zero disruption to infrastructure or workflows. Manufacturing is underway, with shipments to the UK beginning once production is complete. From there, Re4mx will be distributed site-by-site across Holcim’s network, through Fuelre4m’s VIRDIS (Virtual Distribution) system, in preparation for full dosing from 1 September 2025.

France: Ecocem will invest €170m to build four new production lines for its ACT low-carbon cement technology in Fos-sur-Mer and Dunkirk. This follows a €50m investment at Ecocem’s Dunkirk facility to deliver its first production line. The additional manufacturing capacity will come online between 2028 and 2030. At full capacity, ACT production in France will reach 1.9Mt/yr, reducing CO₂ emissions by 800,000t/yr and creating 60 jobs. The French government has reportedly committed to working closely with Ecocem to identify operational and financial solutions to accelerate and deliver the expansion.

Ghana: CBI Ghana and joint venture partner Heidelberg Materials have commissioned the ‘world’s largest’ calcined clay plant in Ghana, according to an announcement by the German producer. The plant has a capacity of 400,000t/yr of calcined clay and uses local raw materials to reduce reliance on imported clinker.

Hakan Gurdal, member of the managing board of Heidelberg Materials, said “Based on calcined clay technology, we can now extend our offering of innovative, high-quality cement products, while reducing CO₂ emissions and utilising the rich local resources. The project has created over 300 local jobs."

Spain: A local cement manufacturer will integrate ‘green’ hydrogen into its production process using a 2MW Neptune II electrolyser from Uk-based supplier ITM Power, according to H2 View news. The electrolyser will supply hydrogen to be co-fired with natural gas in the cement kiln, expected to reduce CO₂ emissions. The method was previously demonstrated in 2021, when Hanson UK (now Heidelberg Materials) and MPA trialled hydrogen co-firing in cement production. It will be the first time that ITM has deployed the system in the cement industry.

Oman: Raysut Cement is reactivating a partnership with China's Sinoma Overseas Development to launch Oman's first waste heat recovery (WHR) power plant at its Salalah site, according to the Oman Daily Observer. The groundwork for the 9MW facility was originally laid in 2018. Once operational, the facility is expected to reduce the plant’s reliance on national grid power by up to 30% and reduce CO₂ emissions by more than 50,000t/yr. Engineering design and site preparations are expected to be revisited before the end of 2025.

India: The Ministry of Environment, Forest and Climate Change has issued a draft notification to establish India’s first compliance-based carbon market, according to The New Indian Express. The draft covers heavy industries such as cement, and lists 186 cement plants belonging to Ultratech Cement, Ambuja Cement, Dalmia Cement and others. These plants must cut greenhouse gas emission intensity (GEI) for two years, starting from the 2025–26 financial year under the Carbon Credit Trading Scheme 2023. Non-compliant producers must purchase carbon credit certificates, or failing this, face penalties from the Central Pollution Control Board. The draft will be finalised following a 60-day public consultation.

Spain: Holcim, IGNIS P2X and Exolum have launched Eco2fly, a project to convert industrial CO₂ emissions into sustainable aviation fuel at Holcim’s Villaluenga de la Sagra plant in Toledo. The facility will capture over 700,000t/yr of CO₂ from the plant’s cement production process and convert it into 100,000t/yr of sustainable aviation fuel using ‘green’ hydrogen. The remaining CO₂ will be stored in geological repositories. Over its first 10 years, the project will reportedly avoid more than 6.5Mt of CO₂ emissions.

Türkiye: Medcem has completed testing of its new waste heat recovery (WHR) facility, which will recover 25% of the energy demand of the plant’s second rotary kiln line commissioned in 2024.

The 9.6MW facility uses an organic rankine cycle (ORC) system to generate electricity from a single heat source. The company says that this will lead to significant cost savings in energy expenses while also reducing CO₂ emissions.

Vietnam: The government will allocate greenhouse gas emissions quotas to 150 facilities across the cement, thermal power and steel sectors, according to a draft decree discussed by the government. Under the proposed roadmap, quota allocation will be implemented in phases over the next five years.

These sectors account for 40% of national emissions, according to the Vietnam Investment Review, and are also subject to the EU’s carbon border adjustment mechanism. The draft decree proposes decentralised development of technical regulations and mutual recognition of carbon credit data with international partners. Quotas will be proposed annually by ministries and submitted to the prime minister for approval.

 Deputy prime minister Tran Hong Ha said “This is a technical decree with many variables. The Ministry of Natural Resources and Environment will provide a controlled framework and guiding principles using a ‘sandbox’ approach, allowing businesses to experiment while regulators monitor, evaluate and make adjustments.”
