Global Construction C-Sink – Public Review

The Global Construction C-Sink Standard certifies buildings and civil engineering works that contain biomass-derived Carbon Sink (C-Sink) Materials. Each certified construction can be registered in 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. The biomass contains organic carbon, which is based on the fact that CO2 was previously actively removed from the atmosphere.

We are thrilled to announce public consultation for our new Global Construction C-Sink Standard. This brand-new and innovative standard is being developed in collaboration with Ithaka Institute for Carbon Strategies and can be used in the construction and building industry.
