Boeing has entered into an agreement with Charm Industrial to remove 100,000 metric tonnes of carbon dioxide from the atmosphere, marking one of the aviation sector’s largest carbon removal deals to date.
Charm removes CO₂ by collecting agricultural and forestry waste, converting it into a hydrocarbon-rich “bio-oil” through pyrolysis, and injecting the substance into underground geological formations, including former oil wells. Once sequestered, the carbon is sold as removal credits to corporate buyers.
The aviation industry has made limited progress in reducing emissions, prompting airlines and aerospace companies to explore alternatives to sustainable aviation fuel. Carbon removal has emerged as a potential option, with estimates suggesting the sector may need to spend at least $60 billion on offsets by 2050 to meet net-zero commitments.
Charm also produces biochar, which can improve soil health when applied to farmland, although adoption remains limited, according to data from the carbon removal registry Isometric.
Financial terms of the Boeing–Charm agreement were not disclosed. In a previous major deal, Charm sold 112,000 carbon removal credits to Frontier for $53 million two years ago, at roughly $470 per tonne. The company has stated its long-term aim to reduce the cost of its carbon removal process to around $50 per tonne.
