Nordic webinar: CO₂-uptake in concrete

Concrete absorbs CO₂ from the atmosphere throughout its lifetime. How can we benefit from of the natural carbonation process on our path to net-zero concrete?

Across the Nordic region, efforts are ongoing on multiple fronts to reduce concrete’s CO₂ emissions. We are replacing Portland cement with supplementary cementitious materials (SCMs) and we will soon utilize CCS cement. The contribution of carbonation is also significant. Carbonation is a natural process that is already occurring, yet few have included it in their Environmental Product Declarations.

How significant is the impact of carbonation, and how should we document it?

In this Nordic webinar, we dive deeper into the role of carbonation from an environmental perspective.

Session Chair: Christoffer Vikne Moen, Heidelberg Materials Northern Europe
