Permanent Carbon Removal at an Industrial Scale

Mitigating climate change will require removing billions of tons of CO₂ from the atmosphere each year.

ZeroEx partners with companies around the world to accelerate permanent carbon removal

ERW plays to your strengths

Landowners and mining companies have the infrastructure and operational capacity. ZeroEx has the ERW expertise and measurement technology. By partnering together, we can rapidly deploy carbon removal projects while maximizing efficiency and minimizing costs.
