Carbstone is listed in the National Environmental Database

At Carbstone, we are celebrating a groundbreaking achievement: all of our blocks now have an MKI (Environmental Cost Indication) value and are listed in the National Environmental Database (NMD).

Stichting NMD is an independent organization that enables an unambiguous calculation of the environmental performance of structures in the Netherlands.

Thanks to this milestone, we are the first manufacturer to be able to demonstrate 100% circular and CO2-negative building blocks according to official standards and have them listed in the national database. This process has been independently reviewed externally, underscoring our commitment to sustainability and transparency.
