Carbonsate
Carbonsate is a climate technology company specializing in efficient, nature-based carbon dioxide removal through biomass storage.
About
Carbonsate is a Berlin-based climate technology start-up dedicated to removing CO₂ from the atmosphere in a scalable, efficient, and cost-effective way using innovative biomass storage solutions. By safely storing excess or invasive plant biomass underground in oxygen-free environments, Carbonsate permanently sequesters carbon that would otherwise be released through decomposition or burning, inspired by natural carbon storage processes. The company certifies its projects through Puro.earth and utilizes advanced sensor technology and real-time monitoring to ensure transparency, credibility, and long-term impact. Their mission is to enable measurable and reliable climate action, supporting the global drive towards net zero emissions by offering high-quality, traceable carbon removal credits to businesses and organizations worldwide. Carbonsate operates internationally, delivering co-benefits for local ecosystems, economies, and communities through projects in Germany, Bulgaria, Colombia, Namibia, and Cameroon.
