Multi-year agreement delivers 105,000 tonnes of permanent CO₂ removal for aviation between 2026 and 2028.
Contracted volumes between the partners now approach $30 million, reflecting growing demand for durable carbon removal.
Airlines are shifting from nature-based offsets toward permanent removal to meet stricter net-zero and regulatory expectations.
Aviation’s Hard-to-Abate Emissions Drive Durable Removal Demand
A new multi-year offtake agreement between Senken and Exomad Green will supply 105,000 tonnes of permanently removed carbon dioxide between 2026 and 2028, with credits earmarked for use in the aviation sector. The deal highlights accelerating demand for durable carbon dioxide removal (CDR) as airlines confront mounting pressure to decarbonize one of the world’s most emissions-intensive industries.
With the latest purchase, Senken’s contracted volumes with Exomad Green now approach $30 million, strengthening a long-term partnership and reinforcing investor confidence in scalable, permanent removal technologies.
Aviation remains among the most difficult sectors to decarbonize due to its reliance on energy-dense fuels and long asset lifecycles. As regulatory scrutiny tightens and voluntary carbon markets face credibility tests, airlines are expanding climate strategies beyond traditional nature-based credits to include engineered and durable removal solutions.
Industrial-Scale Biochar Supply from Bolivia
The credits will be generated from Exomad Green’s industrial biochar facilities in Concepción and Riberalta, Bolivia, including production from its Guarayos facility currently under construction. The company converts sustainably sourced forestry residues that would otherwise be burned or left to decompose into stable biochar through advanced pyrolysis.
The resulting material locks carbon into soils for hundreds of years while delivering co-benefits such as improved soil health, reduced air pollution, and local economic development. The model aligns with growing corporate demand for carbon solutions that deliver measurable environmental and social outcomes alongside climate mitigation.
Exomad Green positions its operations around permanence, traceability, and environmental integrity, criteria that are increasingly central to corporate procurement standards and emerging regulatory frameworks.
“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”.

Due Diligence and Market Integrity Shape Procurement
Senken applies a technology driven procurement process designed to withstand audit and regulatory scrutiny. Through its proprietary Sustainability Integrity Index (SII), projects are evaluated across more than 600 data points. The firm reports rejecting 95 percent of available supply in order to assemble portfolios that meet tightening corporate governance and disclosure requirements.
This emphasis reflects broader changes in voluntary carbon markets, where buyers face rising expectations from boards, investors, and regulators to demonstrate environmental integrity and risk management.
“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.”
Carbon Removal Market Matures as Aviation Leads Adoption
The agreement illustrates the rapid maturation of the carbon removal market, where buyers are prioritizing durability, scalability, and long-term climate impact. Intermediaries such as Senken are playing a growing role in channeling capital toward vetted, industrial solutions capable of meeting corporate net-zero commitments.
For aviation executives and investors, the shift signals a structural evolution in climate strategy. Sustainable aviation fuels and efficiency gains remain critical, but durable removal is emerging as a complementary pathway to address residual emissions that cannot be eliminated in the near term.
As international climate frameworks tighten and disclosure standards evolve, the credibility of carbon strategies will increasingly depend on permanence and verification. Agreements like this one indicate how capital markets and corporate procurement practices are converging around higher-integrity solutions, shaping the next phase of global decarbonization.
