From pollutant to building material - we create living space from CO₂
We bind CO₂ in houses. We also create certified CO₂ sinks and follow the Global Construction C-Sink Standard for maximum climate effectiveness.
CO₂ sink certification
Developed by the Ithaka Institute and published by Carbon Standards International, the Global Construction C-Sink Standard 0.91 offers innovative options for carbon dioxide removal (CDR) and climate protection through construction.
The standard is based on the latest Carbon Removals and Carbon Farming (CRCF) Regulation of the European Union (EU/2024/3012)
Certification process according to the Global Construction C-Sink Standard
-
Biomass carbon (e.g. Hempcrete) is tracked from cultivation to the construction site using digital dMRV systems.
-
All greenhouse gas emissions (cultivation, transportation, processing) are recorded in an emissions portfolio and offset with geological (CO₂, N₂O) or temporary (CH₄) carbon sinks.
-
After verification by certified C-sink managers and accredited certifiers, the C-sink is entered in the Global Carbon Register.
-
Annual checks ensure the integrity of the temporary C-sink (e.g. 60 years).

Marketing opportunities
CO₂ offsetting and certificate trading: Certified Hempcrete buildings open up lucrative opportunities for CO₂ offsetting and additional income. Each ton of Hempcrete binds 200 kg of CO₂e, with a temporary C-sink value of around €30 over 50 years (at €3/t aCO₂e annually). After offsetting the production emissions (e.g. €1.65/t Hempcrete at €150/t geological C-sink), the residual value can be marketed as global cooling credits. Companies that want to offset their carbon footprint pay a premium for these tangible, verifiable C-sinks - especially with the Global Construction C-Sink Label. In addition, C-Sink Options enable the pre-selling of future cooling effects, ensure early liquidity and annual validations guarantee long-term credibility. With the eco-friendly appeal of Hempcrete, you can position your project as a sustainability leader, attract green investors and increase real estate value in a sustainability-conscious market.
