Ecocem, Europe’s leading provider of low-carbon cement technologies, today announced it has achieved ASTM C1157 certification in the US. This major milestone affirms the performance, durability and reliability of ACT for use in the US market, demonstrating a significant step forward in terms of global net zero ambitions.

Unlike traditional cement specifications that prescribe raw material composition, this certification is a performance-based standard that allows for innovative formulations. The accreditation confirms ACT meets or exceeds the industry benchmarks for strength and durability, while reducing carbon emissions and energy use.
Surpassing these standards, Ecocem’s ACT technology proves that sustainable cement can also be high-performing and highly efficient in terms of material usage and cost-effective.
At a time when the US imports nearly a quarter of its cement, Ecocem’s technology offers a domestic solution that strengthens local supply chains, supports industrial competitiveness, and aligns with energy and infrastructure policy goals across the political spectrum. More generally, it signals the scaling of cleantech innovation into one of the world’s largest construction markets, a milestone in building the global momentum required to meet climate goals.
“This is a significant moment for Ecocem and for low-carbon cement globally," said Donal O’Riain, Founder and Group Managing Director of Ecocem. “Over the past 10 years our solutions have seen significant traction across Europe. The US is one of the largest cement markets in the world, and this certification will support integration into existing supply chains and offers a pathway for the sector to rapidly decarbonise through improved efficiency and without increasing costs or complexity”
This announcement comes as Ecocem moves forward with its first North American project: a proposed Terminal and Milling Operation at the Port of Los Angeles. Still in the early stages of planning and review, the facility intends to establish a reliable, resilient supply chain for producing low-carbon, high-performance cement in California and support the state with the durable infrastructure required for long-term economic growth.
ACT, Ecocem’s scalable low-carbon cement technology, can reduce CO2 from cement manufacturing while delivering the necessary strength, durability and workability required in any concrete it is used to manufacture. ACT reduces cement emissions by cutting clinker content – the key reactive component in cement and responsible for over 90% of its carbon emissions - by up to 70% and replacing it with abundantly available materials, such as limestone, and locally-sourced supplementary cementitious materials (SCMs).
Clinker, the key reactive component in cement, is responsible for over 90% of its carbon emissions. By optimizing the interaction and performance of SCMs and engineered mineral admixtures, ACT not only lowers clinker content but also enables much more efficient use of SCMs, delivering high-performance, low-carbon cement at scale.
This announcement follows a series of key ACT milestones in Europe, including recent regulatory approvals in France, new investment in production lines announced at Dunkirk, and partnerships with global construction leaders such as Bouygues, Vinci and Titan Group — all of which demonstrate Ecocem’s readiness to scale.
