Charm uses plants to capture CO2 from the atmosphere. The company converts waste biomass into bio-oil through fast pyrolysis. That means heating things like plant waste up to 500℃ for a few seconds in an oxygen-free chamber. The stable, carbon-rich liquid is injected deep underground through EPA-regulated injection wells, where the bio-oil sinks and solidifies in place for permanent storage. This removes CO2 permanently from the atmosphere, out of reach of wildfires, soil erosion and political folly.
Permanently removed 5,000 tCO2 in 2021 – the largest permanent removal by any one company at the time
Highest levels of additionality
Uniquely transparent lifecycle assessment with measurement, reporting and verification
