Exomad Green and Senken have entered into a multi-year offtake agreement to supply 105,000 tonnes of permanent carbon dioxide removal (CDR) credits to the aviation industry between 2026 and 2028. Based in Bolivia, Exomad Green operates industrial-scale biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More facilities that will source these credits, while Berlin-based Senken serves as the procurement partner. This transaction brings the total contracted volume of durable carbon removal between the two organizations to nearly $30 million. The deal signals a significant move by the aviation sector to incorporate high-integrity, engineered removals into its long-term net-zero strategies.

The primary challenge addressed by this partnership is the difficulty of decarbonizing the aviation industry, which is characterized by high residual emissions and increasing regulatory pressure. Under the International Civil Aviation Organization’s CORSIA scheme, airlines face rising compliance costs and a need for credits that withstand rigorous audit and board-level scrutiny. Traditional nature-based offsets often lack the permanence and transparency required by modern climate integrity standards. Consequently, enterprise buyers in this sector require a consistent supply of “audit-ready” credits that offer defensible proof of permanent sequestration to satisfy both regulators and internal stakeholders.

The solution utilizes industrial biochar production to provide a stable and measurable carbon sink. Exomad Green produces biochar by subjecting sustainably sourced forestry residues to advanced pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More, a process that prevents the biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More from decomposing and releasing carbon dioxide back into the atmosphere. The resulting material is capable of sequestering carbon for hundreds of years. To ensure the quality of these removals, Senken employs its proprietary Sustainability Integrity Index, a vetting framework that evaluates projects against more than 600 data points. This rigorous filtering process ensures that the credits delivered to the aviation sector meet the highest standards of climate integrity.

The outcomes of this agreement include the successful redirection of capital toward permanent, engineered carbon removal technologies. The credits will be supplied from Exomad Green’s facilities in Concepción and Riberalta, as well as the new Guarayos facility, which is poised to become one of the world’s largest biochar sites. For the aviation industry, this deal provides a structural shift toward a diversified and defensible carbon portfolio. Beyond carbon sequestration, the operations support local socioeconomic development in Bolivia through green job creation and the donation of biochar to indigenous communities for soil regeneration.
