We deliver permanent, certified, ready-to-scale carbon removal by storing biomass in oxygen-free environments like deep underground mines and marine sediments.
Plants capture 50 gigatons of CO2 every year. But they eventually decompose, releasing all of that carbon back into the air. What if we could preserve it in an environmentally-safe way and stop it from cycling back into the atmosphere?
Our carbon removal mirrors and accelerates the Earth’s natural cycles.
We don’t use combustion or industrial processing, making Rewind’s method the most energy-efficient carbon removal approach.
With hundreds of thousands of disused mines and oxygen-free sedimentary zones in oceans, our approach is built to work in any geographical location.
From repurposing mines to supporting local ecosystems and creating jobs, every project drives positive change and restoration
As of 2025, we’re issuing certified carbon credits, with plans to scale to 100,000 tons by 2027. By 2030, we aim to remove 1 million tons of CO2 per year through our global portfolio of carbon removal projects.
