Low-carbon concrete is increasingly in demand among builders who want to reduce the environmental footprint of their buildings. This type of concrete is defined as concrete where measures have been taken to limit greenhouse gas emissions, measured as CO2 equivalents, weighted according to GWP (Global Warming Potential).
To be classified as low-carbon concrete, the concrete must have an EDP (Environmental Product Declaration) documenting its carbon emissions for its entire life cycle. The concrete’s greenhouse gas emissions can only deviate by a maximum of 5% from its declared value. We used class A low-carbon concrete for the projects in our Molde and Volda factories.
In Molde, we used 503 cubic metres of concrete for this project. By choosing class A concrete, we saved 60 tonnes of CO2 equivalents compared to standard concrete. In Volda, 690 cubic metres were used. This saved us 95 tonnes of CO2 equivalents.
By choosing more sustainable types of concrete, we reduced our CO2 footprint by 155 tonnes across both factory locations. Additionally, we optimised the machine foundations through detailed strength calculations, allowing us to reduce the overall amount of concrete used. These efforts helped minimise our environmental impact while maintaining structural integrity.
