We offer a wide range of services for positive carbon cycles. We work with you to enable your business to achieve a positive balance between the generation of greenhouse gases and the binding of carbon from the atmosphere, thereby cooling the climate.
Biochar Standards
Biochar stores carbon in a stable form and improves soil health. Our biochar standards ensure quality, traceability, and verified carbon removal for multiple scales of production.

Global Artisan C-Sink
Certification for sustainable artisan biochar production in lower-income countries, ensuring climate benefits, soil health, and farmer income.

European Biochar Certificate (EBC)
Certification for sustainable biochar production and use in industrial countries, ensuring quality, compliance, and diverse applications

World Biochar
Certificate (WBC)
Global certification for sustainable biochar production, ensuring strict quality, carbon-positive impact, and broad applicability.
Carbon Sinks
Our carbon sink services enable you to calculate and certify your positive climate performance in the form of carbon sinks. The CO₂ equivalents bound by your measures can either be traded on a CO₂ marketplace or compensated with public funds.
For this purpose, we provide you with our Global C-Sink Registry. All carbon sinks listed there have public documentation to ensure transparency of your and our work and to build trust in the carbon sinks. All carbon sinks in our registry are permanent, credible, unique, measurable, additional, and temporally precise, as confirmed by ICROA.
