Ireland faces a dual challenge: delivering the infrastructure and housing needed for a growing population while dramatically reducing the carbon footprint of construction. Engineers are central to solving that challenge.
Cement is the backbone of modern infrastructure. From homes and hospitals to bridges and transport systems, it is one of the most widely used materials in the world. Yet it is also one of the most carbon-intensive, accounting for approximately 7-8% of global CO₂ emissions. As the construction industry faces increasing pressure to decarbonise, the question is no longer whether change is needed, but how quickly it can be achieved.

As Ireland works towards its Climate Action Plan targets, reducing embodied carbon in construction is becoming increasingly important. For engineers specifying materials on projects, cement selection is one of the most immediate opportunities to reduce carbon at scale.
Ecocem: Rethinking cement from the ground up
Ecocem, a leading provider of low-carbon cement technologies, has spent more than two decades developing solutions that dramatically reduce the clinker content in cement without compromising performance.
By re-engineering the role of supplementary cementitious materials, Ecocem’s products significantly lower embodied carbon while maintaining the strength, durability, and reliability required for modern construction. Importantly, these solutions are designed for real-world application, compatible with existing standards, supply chains, and construction practices.
Innovation and technology
By reducing reliance on clinker, Ecocem enables substantial carbon savings without requiring fundamental changes to construction methods. This allows engineers, contractors, and developers to make immediate progress toward sustainability goals while maintaining project efficiency and structural integrity.
ACT, Ecocem’s latest technology, delivers a sustainable, low-carbon and cost-effective solution that can be produced at scale using existing infrastructure. ACT delivers up to 70 per cent reduction in carbon emissions and is currently progressing toward commercial deployment.
The momentum behind ACT was further reinforced recently through a collaborative industry and research initiative involving Cairn, University College Dublin (UCD), Kilsaran, and Ecocem, which secured funding to support the development and deployment of innovative low-carbon cement technologies in Ireland. The project highlights the growing role of cross-sector collaboration in accelerating the transition to more sustainable construction practices.
Innovation for low-carbon mortars
Within this wider portfolio of innovation, Ecocem works on enabling low-carbon solutions for all construction applications, including dry-mix mortars. To allow mortar industries to maximise their carbon footprint reduction, Ecocem is working on specific grades that help improving performances of mortar applications, without compromising on workability.
This new solution, with a project name DMM1-X, has been tested in different dry mix applications, as tile adhesives, self-levelling underlayments and technical mortars, showing strong compatibility with all main dry mix raw materials and formulations.
Ecocem new low-carbon high performance technology, DMM1-X, will be presented at the UK & Ireland Drymix Mortar Meeting on June 8.
Engineering a lower-carbon future
Decarbonising cement is one of the most impactful steps the construction industry can take in addressing climate change. It requires collaboration between material scientists, engineers, policymakers, and industry leaders.
Ecocem’s role is to deliver practical, scalable solutions that allow us to build the infrastructure of the future. As the industry continues its transition, low-carbon cement is no longer an alternative; it is becoming the new standard.
