Santa Cruz, Bolivia
12th February 2026 — Exomad Green, the largest durable carbon dioxide removal (CDR) supplier, today announced a new multi-year offtake agreement with Senken covering 105,000 tonnes of permanently removed CO₂ across the 2026–2028 period. The credits are destined for deployment within the aviation sector, one of the most challenging industries to decarbonize and among the fastest to adopt durable carbon removal.
With this agreement, Senken’s total contracted volumes with Exomad Green now approach $30m of durable carbon removal, underlining Senken’s role as a long-term portfolio partner and signaling increasing market confidence in large-scale, permanent CDR solutions.
The agreement also reflects a broader shift within the aviation sector. Airlines are increasingly diversifying their climate portfolios, moving from an exclusive reliance on nature-based carbon credits toward permanent carbon removal as part of longer-term net-zero strategies.
The credits will be supplied from Exomad Green’s industrial biochar operations in Bolivia in Concepción and Riberalta, including volumes from its new Guarayos facility, currently under construction. The agreement further demonstrates Exomad Green’s ability to deliver carbon removal at industrial scale while maintaining high standards for permanence, traceability, and environmental integrity.
“This agreement reinforces a clear trend we’re seeing in the market,” said Diego Justiniano, CEO of Exomad Green. “Aviation is one of the most demanding sectors when it comes to climate integrity. The fact that capital is now flowing into permanent carbon removal signals a structural shift in this industry”
Exomad Green produces biochar from sustainably sourced forestry residues that would otherwise be incinerated or left to decompose. Through advanced pyrolysis, the biomass is converted into stable biochar capable of storing carbon in soils for hundreds of years, while also delivering co-benefits such as improved soil health, reduced air pollution, and positive local socio-economic outcomes.
Senken applies a rigorous, technology-driven approach to carbon procurement. Through its proprietary Sustainability Integrity Index (SII), the company vets every project against 600+ data points, rejecting 95% of market supply, to build audit-ready carbon credit portfolios that meet the rising expectations of corporate buyers and regulators alike.
“We’re seeing repeat demand from enterprise buyers who need carbon portfolios they can defend to their boards, their auditors, and increasingly, to regulators,” said Adrian Wons, CEO of Senken. “This agreement reflects how permanent removal is becoming a core component of credible corporate climate strategies, and why rigorous due diligence matters more than ever.”
The agreement, with carbon credits under the puro.earth registry, highlights the rapid maturation of the carbon removal market, as buyers increasingly prioritize durability, scale, and long-term impact — and as intermediaries play a key role in channeling capital efficiently toward trusted, industrial solutions.
