A new multi year offtake agreement between Senken and Exomad Green will deliver 105,000 tonnes of permanently removed carbon dioxide between 2026 and 2028, with the credits allocated to aviation sector buyers. The transaction reflects growing demand for durable carbon removal as airlines confront the structural challenge of reducing emissions in one of the most carbon intensive industries globally.

With this latest agreement, Senken’s contracted volumes with Exomad Green approach 30 million dollars, reinforcing a long term commercial relationship and signalling increasing investor and corporate confidence in scalable removal technologies.

Aviation’s Residual Emissions Create Structural Demand

Aviation remains among the most difficult sectors to decarbonise due to its dependence on energy dense fuels and long lived aircraft fleets. While sustainable aviation fuels and operational efficiencies can reduce emissions intensity, a significant share of residual emissions is expected to persist for decades.

As regulatory scrutiny tightens and voluntary carbon markets face credibility pressure, airlines are reassessing traditional offset strategies. Nature based credits, once dominant in aviation climate claims, are increasingly being supplemented or replaced by engineered and permanent carbon removal solutions that offer longer duration storage and stronger verification frameworks.

The agreement between Senken and Exomad Green reflects this transition toward higher integrity solutions capable of withstanding investor, board level and regulatory review.

Industrial Scale Biochar Production in Bolivia

The credits will originate from Exomad Green’s biochar facilities in Concepción and Riberalta, Bolivia, including output from its Guarayos facility currently under development. The company converts sustainably sourced forestry residues that would otherwise be burned or left to decompose into stable biochar through advanced pyrolysis processes.

Biochar stores carbon in a solid form that can remain stable in soils for centuries. Beyond carbon sequestration, the process can improve soil quality, reduce open burning emissions and generate local economic activity. This combination of permanence and co benefits is increasingly aligned with corporate procurement preferences.

Exomad Green has positioned its operations around permanence, traceability and environmental integrity, criteria that are becoming central to both voluntary standards and emerging compliance frameworks.

Procurement Standards Reflect Rising Governance Expectations

Senken applies a technology driven due diligence framework through its Sustainability Integrity Index, which evaluates projects across more than 600 data points. The firm reports rejecting the majority of available supply in order to assemble portfolios capable of meeting tightening corporate governance requirements.

This approach mirrors a broader evolution in carbon markets. Buyers are under growing pressure from auditors, investors and regulators to demonstrate that carbon claims are supported by robust verification and durable impact. Procurement strategies are therefore shifting from volume based purchasing toward risk screened, high integrity portfolios.

For aviation companies operating under increasing disclosure obligations, defensibility has become as important as emissions reduction itself.

Carbon Removal Moves Into the Core of Climate Strategy

The scale of the agreement illustrates how the carbon removal market is maturing. Durable removal is moving from a niche supplement to a core element of corporate net zero planning, particularly in hard to abate sectors such as aviation.

Intermediaries like Senken are playing a larger role in directing capital toward industrial scale removal platforms that can deliver predictable volumes over multiple years. For project developers, long term offtake contracts provide revenue visibility and support further capacity expansion.

For airlines and investors, the shift signals a structural recalibration of climate strategy. Emissions reduction remains the priority, but credible pathways increasingly include permanent removal to address unavoidable residual emissions.

As climate disclosure standards strengthen globally, agreements focused on permanence, transparency and verification are likely to shape the next phase of aviation sector decarbonisation.
