FAQ

Yes. We work with leading registries and carbon removal standards, such as Isometric, and have developed a full and comprehensive digital MRV (Monitoring, Reporting, and Verification) system.

Rewind delivers permanent, certified carbon removal by preserving plant biomass in anoxic (oxygen-free) environments (such as deep mines and marine basins) where carbon remains locked away for thousands of years.

Traditional offsets avoid increasing emissions instead of actually removing existing emissions from the atmosphere. Rewind removes CO₂ already in the atmosphere and stores it permanently. Our approach is scientifically validated, third-party certified, and ready to scale.

Rewind's first commercial project, Project Ushba, is now operational in Georgia, where we store surplus plant residue in the sealed chambers of a deep mine void. It follows pilot work in the Black Sea, one of the world's largest natural anoxic basins, where we pioneered peer-reviewed research on marine biomass storage. But these locations are just the beginning. Rewind's model is built to be replicated wherever biomass meets anoxic storage, making it designed to scale globally.

Biomass decomposes quickly in the presence of oxygen. But by placing it in oxygen-free environments, decomposition slows radically and carbon remains safely stored for more than a millennia, geologically locked in.

Rewind's model is designed to work wherever surplus biomass meets anoxic storage conditions. There are hundreds of thousands of unused mines around the world; vast sedimentary zones in oceans and estuaries, and marine basins like the Black Sea are capable of storing gigatons of CO₂. By 2030, Rewind aims to remove one million tons of carbon annually through a growing network of deep mines, sediments, and marine basin carbon removal projects.

No oxygen means limited decomposition and therefore no carbon released. These natural conditions preserve carbon securely and durably. Rewind applies this model to anywhere where oxygen isn't present.

The Black Sea is one of the largest natural anoxic basins, a place where the deep waters contain no oxygen, which prevents decomposition and allows carbon to be safely preserved without emissions for thousands of years.

No. The Rewind model works wherever surplus biomass and oxygen-free geology meet. This includes marine basins, deep mines, and sedimentary zones worldwide.

Biomass refers to carbon-rich plant material, including sawdust and crop residue, which absorbs CO₂ as it grows. Without intervention, this biomass typically decomposes or is burned, releasing that carbon back into the air. Preserving biomass in anoxic storage stalls decomposition and therefore prevents CO₂ cycling back into the atmosphere.

We use surplus, sustainably sourced surplus plant residue (byproducts from sawmills and agriculture) that would otherwise emit carbon through decomposition or burning. All of it is non-edible, non-commercial, and not grown for Rewind.

Yes. All biomass is sourced from certified, responsible local suppliers. We follow strict sustainability criteria including not competing with food systems and using transparent supply chains with chain-of-custody tracking.

Approximately 1 ton of dry biomass holds 1 ton of CO₂. The exact ratio depends on the specific type of biomass and its moisture content.

Not at all. Moving biomass takes far less energy than heating it. Rewind's approach relies on transportation and natural storage conditions, making it one of the most energy-efficient carbon removal methods available.

Yes. Our method is grounded in natural processes, our storage sites are geologically stable and oxygen-free, and we monitor processes rigorously. Projects are designed to protect -- and restore -- surrounding ecosystems.

Rewind restores. We repurpose unused infrastructure, reduce methane emissions and wildfire risks, support local habitats and rivers, and deliver measurable co-benefits for communities and ecosystems.

Yes. Our method is energy efficient and scalable through replication, not complexity. It's designed for global deployment without compromising safety.

No. Carbon removal is essential alongside emission cuts. Even if emissions dropped today, legacy CO₂ must still be removed to meet global climate goals.

Trees help, but are fragile carbon sinks. They're vulnerable to fire, disease, and climate shifts. Our solution offers durable, certified carbon removal that's complementary to nature-based options like reforestation.

Plants absorb CO₂ as they grow, storing it in their biomass. Without intervention, when the plant dies, that biomass decomposes, releasing the CO₂ back into the atmosphere. Rewind interrupts this process by preserving surplus biomass in oxygen-free environments where decomposition can't occur, keeping carbon out of the air for thousands of years.

This is true removal. Our process takes carbon dioxide that's already in our atmosphere and stores it permanently, removing it from the carbon cycle.
