🔑 Key Takeaways Multi-year DAC offtakes are becoming the norm. Sirona Technologies’ deal via Patch follows a pattern: buyers are moving from exploration to long-term procurement with multi-year contracts securing permanent removals. The shift matters — it signals genuine market maturation, not just pilot-stage experimentation. Aviation’s CDR paradox deepens. Boeing is buying 40,000+ tonnes of quality CDR via Carbonfuture, while the SASHA Coalition argues that CORSIA lets the sector avoid harder decarbonization — leaving 1.1 billion tonnes unregulated since 2012. The gap between voluntary ambition and compliance reality is widening. ...

Boeing just signed one of the aviation sector’s largest carbon removal procurements ever: at least 40,000 tonnes of durable CDR through Carbonfuture, sourced from four biochar projects across the Global South. Full disclosure: Carbonfuture is a Carbon Drawdown Initiative portfolio company. We’ve been tracking their progress closely, and this deal validates exactly the kind of infrastructure the CDR market needs. Why This Matters Aviation is one of the hardest sectors to decarbonize. Planes can’t run on batteries (not yet, anyway), and sustainable aviation fuels are still scaling up. So for residual emissions — particularly Scope 3 business travel — durable carbon removal is the only honest answer. ...
