ZeroEx is a German climate tech company scaling permanent carbon removal through Enhanced Rock Weathering (ERW), a nature-based solution grounded in science, built for scale, and designed for real-world impact.
We collaborate closely with farmers and local partners to deploy ERW across agricultural regions in Germany, applying basalt rock dust from nearby quarries to remove CO₂ from the atmosphere. At the same time, this process enriches soils, reduces the need for chemical inputs, and strengthens rural livelihoods.
ZeroEx is the first ERW company in Europe, and the second globally, to have its project independently validated by Isometric, setting a new benchmark for scientific integrity, regulatory alignment, and market trust in carbon removal.
We prioritize carbon removal that is measurable, verifiable, and scalable. Our MRV systems are developed in partnership with institutions such as Yale, Princeton, and the University of Cambridge, and all of our credits are issued under the highest-quality carbon removal standards.
We believe climate solutions must be practical, cost-effective, and community driven. By combining science, local infrastructure, and trusted partnerships, we are building a next-generation carbon removal model that supports farmers, delivers verified impact, and helps accelerate the global net-zero transition.
„The IPCC science is clear: achieving net-zero emissions requires gigaton-scale carbon removal. At ZeroEx, we transform the mining byproduct basalt into a permanent carbon sink. This gives farmers healthier soils today and ensures a safer climate for the planet for millennia.“
