C5Lab’s First International Webinar Discussed Evidence-Based Pathways for Cement Industry Decarbonisation
The webinar “Decarbonising Cement: Evidence, Tools and Pathways – Insights from national LCA modelling, green hydrogen and CO₂ capture” took place on 20 January 2026, marking the first international webinar organised by C5Lab. The initiative attracted 122 registered participants, with 92 attendees effectively participating, representing industry, academia, and organisations involved in public policy design at both national and international levels.
The event opened with a welcome address by Margarida Mateus, Executive Director and Technical-Scientific Coordinator of C5Lab, who highlighted the role of the collaborative laboratory in promoting scientific and technological solutions for industrial decarbonisation. The opening session was delivered by Paulo Ferrão, Professor at Instituto Superior Técnico, who emphasised the importance of collaborative laboratories and provided an overview of the two C5Lab projects, underlining their strategic relevance for the development of scientific and technological tools to support decarbonisation in the cement sector.
Francisco Capucha, Project Manager at C5Lab, then presented the project “LCA Model of the Portuguese Cement”, focused on the development of a national Life Cycle Assessment (LCA) model for Portuguese cement, designed as a decision-support tool for industry and for evidence-based public policy formulation, grounded on real and representative sector data.
Subsequently, Melissa Bacatelo, LCA & European Projects Coordinator at C5Lab, presented the project “The Roles of Green Hydrogen and CO₂ Capture in Cement Sector Decarbonisation”, addressing the contribution of green hydrogen and CO₂ capture as enabling technologies for deep decarbonisation of the cement industry, as well as their impacts, limitations, and potential integration across different technological scenarios.
The webinar concluded with final remarks by Cecília Meireles, President of the Board of Directors of C5Lab and Secretary-General of ATIC – Portuguese Cement Association, who reaffirmed the importance of C5Lab and of this initiative, as well as the value of strengthened collaboration between research and industry.
