Exomad Green and Senken Sign 105,000 Tonne Carbon Removal Deal for Aviation

Carbon removal provider Exomad Green and carbon credit procurement company Senken have signed a multi-year offtake agreement to supply 105,000 tonnes of permanently removed carbon dioxide between 2026 and 2028, targeting the aviation sector. The credits will be generated from Exomad Green's biochar operations in Bolivia.

Exomad Green produces biochar by heating sustainable forestry residue waste biomass in the absence of oxygen, creating a stable carbon form delivered to local communities for agricultural soil improvement. The company currently operates two biochar facilities in Bolivia, with a third under construction and scheduled to come online in 2025. The new agreement brings total contracted volume between Senken and Exomad Green close to USD 30 million, reflecting rising enterprise demand for durable, high-integrity carbon removal credits that can withstand auditor and regulatory scrutiny.

The agreement reflects a structural shift in aviation's approach to carbon management, with airlines increasingly diversifying away from nature-based credits toward permanent carbon removal as part of longer-term net-zero strategies. Biochar has gained traction as a carbon dioxide removal solution due to its scalability, relatively low cost compared to engineered CDR technologies, and soil fertility benefits. For the aviation sector, which faces mandatory carbon obligations under CORSIA and voluntary corporate climate commitments, permanent removal credits represent a more defensible option compared to traditional avoidance-based offsets.

Senken CEO Adrian Wons noted that enterprise buyers are seeking carbon portfolios they can defend to boards, auditors, and increasingly regulators, driving repeat demand for permanent removal. The 2026–2028 delivery timeline aligns with a period of heightened scrutiny of voluntary carbon market quality. Bolivia's forestry residue feedstock supply and the company's expansion to a third facility provide scale visibility for buyers. For Indian companies building carbon credit strategies under emerging SEBI and CCUS-related frameworks, the Exomad–Senken model illustrates how structured offtake agreements underpin high-integrity CDR supply chains.
