Global Construction C-Sink – Extension of public consultation period

Good day

We are pleased to extend the public consultation for our new Global Construction C-Sink Standard. Due to the great interest in our new standard, we are extending the public consultation period until 30 April 2025 and are also postponing the public webinar.

The Global Construction C-Sink Standard

The Global Construction C-Sink Standard certifies buildings and civil engineering works that contain biomass-derived Carbon Sink (C-Sink) Materials. The biomass contains organic carbon, which is based on the fact that CO2 was previously actively removed from the atmosphere. This biomass, examples of which include hemp or biochar, is incorporated into the building materials and thus represents a carbon sink. Each certified construction is considered a C-Sink Unit and can be registered in our publicly available Global C-Sink Registry if all GHG emissions that were caused by the production and transportation of the embedded Construction C-Sink Materials were offset.

Consultation Period: 17 February – 30 April 2025

We welcome feedback from all stakeholders during this period. Your input is invaluable to our standard development process, ensuring transparency and informed decision-making.
