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.

Costa Rica: Holcim Costa Rica has issued its first sustainability report, which states that it reduced CO₂ emissions by 19% between 2018 and 2024. During the last year, the company prevented the release of more than 4600t of CO₂ thanks to improvements in thermal efficiency. It also processed more than 72,000t of municipal and industrial waste as energy or alternative fuel in cement production and reused more than 90% of the industrial water consumed at its cement plant. It reported that it has reached gender equality within its executive team, with 50% female and 50% male leadership.

Holcim Costa Rica’s 2030 goals include achieving a 32% reduction in primary CO₂ emissions from cement plant operations, a 5% reduction in electricity consumption and a 21% reduction in logistics emissions, while reaching a net positive impact on biodiversity, and reducing the use of fresh water.

Mexico: Holcim has placed Mexico at the centre of its NextGen Growth 2030 strategy to ‘drive profitable expansion’ in Europe, Australia, North Africa and Latin America following the spin-off of its North American business. Mexico now plays a strategic role in scaling sustainable construction solutions across the region and will allow Holcim to respond to key global trends such as urbanisation, housing shortages, resilient infrastructure and environmental sustainability.

Holcim Mexico CEO Christian Dedeu said “Mexico is now a strategic market where we will scale innovative solutions for circular and low-carbon construction. Our goal is to triple the recycling of demolition materials, double the Disensa store network and expand our sustainable offering through ECOPact and ECOPlanet.”

Dedeu added “In a region facing major social and environmental challenges, Mexico and Latin America have the potential to lead a new era of sustainable construction. At Holcim, we are committed to scaling solutions that address the climate emergency while building progress for people and the planet.”

US: Hoffmann Green Cement Technologies has obtained ASTM C1157 certification for its H-UKR 0% clinker cement after several months of testing and trials at the University of Miami.

The benchmark standard evaluates cements on their performance, regardless of their composition. H-UKR cement is now officially recognised as a hydraulic cement that can be used in all general construction applications, whether structural or non-structural. Hoffmann Green said that this is the first time that a 0% clinker cement has obtained this certification.

Co-founders Julien Blanchard and David Hoffmann said “This international technical recognition marks a decisive step forward in our certification process, which is part of a broader ambition to expand the applications of our 0% clinker cement through continuous innovation. It validates the reliability and sustainability of our technology on a global scale, in accordance with the most demanding standards. With this certification, H-UKR has confirmed itself as a game changer technology capable of profoundly transforming an industry that has remained unchanged for more than two centuries.”

Ghana: Ghacem has launched ECO COOL, Ghana’s first eco-friendly cement, according to My Joy Online news. The producer says the new product reduces environmental impact while maintaining high construction standards.

At the launch event, managing director Frank Huber said “At Ghacem, we want to lead the path in sustainable construction. We’ve set a clear target — to become 100% CO₂ neutral by 2050. ECO COOL is designed for all building applications, but with significantly lower environmental impact.”

Togo: Cement producers in Togo have committed to reduce CO₂ emissions by 2050 by lowering the clinker factor and increasing the use of alternative fuels. At a meeting in Lomé on 30 June 2025, manufacturers set out a roadmap that includes large-scale adoption of limestone calcined clay cement (LC3) to reduce clinker content from 65% to 40%, potentially cutting emissions by up to 40% without sacrificing performance, according to the Togo First newspaper.

The strategy also involves replacing coal with agricultural or municipal waste. Industry data shows that cement production generated 0.9Mt of CO₂ in 2023, which could rise to 1.8Mt by 2050 without intervention. Manufacturers are seeking regulatory support to help deliver the roadmap, which aligns with Togo’s Paris Agreement commitments.

Sweden: SaltX has announced a partnership with Holcim to develop technology and solutions that electrify and enable the decarbonisation of the entire cement manufacturing process. As part of the partnership, Holcim is becoming a strategic shareholder in SaltX through an investment of approximately US$4m. 

The companies intend to co-develop and advance SaltX’s electrification technology for calcination, including the production of Portland cement clinker. The goal is to be the first in the world to establish a scalable plant concept for fully electrified cement facilities. The parties’ intention is for the partnership to be extensive, featuring a collaborative go-to-market and scale-up plan. The initial focus is on developing the world’s first all-electric pilot plant for emission-free cement production. This will set the foundation to establish multiple large-scale production facilities based on SaltX’s electrification technology.  

Greece: Titan Group has been named by Time Magazine as one of the most sustainable companies in the world, rising 158 positions to 150th in the annual list of 500 companies. Titan Group said that it is the highest-ranked building materials company and one of only a handful on the list. Time Magazine and data firm Statista assessed companies based on external ratings, commitments and various environmental and social Key performance indicators (KPIs) disclosed in externally-assured reports.

Leonidas Canellopoulos, Chief Innovation and Sustainability Officer at Titan Group, said "Being named one of the world’s most sustainable companies by Time for the second year in a row is a powerful endorsement of our growth strategy in action. Sustainability is woven into every decision we make – from bold innovation in new products and decarbonised processes to transparent execution.”

Norway: Heidelberg Materials CEO Dominik von Achten and Crown Prince Haakon of Norway have inaugurated the new carbon capture and storage (CCS) unit at the Brevik cement plant. The event was attended by 320 guests, inxluding Norwegian energy minister Terje Aasland. Von Achten said the producer’s ‘zero-CO₂’ cement, evoZero, is fully sold out for 2025. The Brevik CCS unit will capture 400,000t/yr of CO₂, equivalent to 50% of the plant's emissions. The first CO₂ has already been successfully captured, liquefied and temporarily stored, with injection into subsea reservoirs scheduled for August 2025. 

Von Achten said “Personally, I love the collaboration part of it because this is a masterpiece of global, national, European, in fact, global collaboration. Without the Norwegian government support we would probably not alone have a part in this project. The Norwegian government has significantly de-risked the project for us. That's why we are standing here today and celebrating this important milestone.”

He added “We can’t expect governments to finance these projects for the coming decades – it must work commercially. We have a physical product from Brevik that we will be delivering to Oslo and to other parts of Norway. We also have a virtual product, which will be like a purchase of a renewable energy contract, so that we can virtually allocate evoZero to Paris, to Berlin, to wherever it is needed.”

Von Achten said “The CO₂ concentration in our flue gas – at 20% – is much higher than in the atmosphere, so we have a huge technology and commercial advantage over direct air capture (DAC) approaches. I would say that our evoZero product brings significant commercial advantages to our customers.”

Yara International CEO Svein Tore Holsether said “There will be no green transition with red numbers.”

Energy minister Terje Aasland said Norway has been safely sequestering CO₂ in the Sleipner oil-field since 1996 and that storage is safe and permanent.
