The best of nature and tech

Charm uses plants to capture CO₂ from the atmosphere, saving the need for energy-intensive carbon capture. We convert biomass into its most stable form for sequestration, keeping carbon out of the atmosphere and safe from wildfires, soil erosion and political folly.

Fastest growing carbon removal technology

01 /

Nature's carbon capture

Cellulosic biomass already captures 100+ Gt CO₂/year. We collect it and put it through a process called fast pyrolysis.

02 /

The ideal injectant

The biomass breaks down into bio-oil which is rich in carbon but not useful as a fuel source.

03 /

Million-year storage

The bio-oil is prepared and injected into EPA-governed injection wells, where it is permanently stored.

Drive more impact every year

By subscriping to carbon removal, you'll help Charm come down the cost curve and advance the geologic permanence of traditional carbon offsets.
