In this episode of our Sustainability Talks podcast, our Managing Partner Patrick Sheehan sits down with Christoph Gebald, CEO & Founder of Climeworks, the global leader in carbon dioxide removal. Together, they explore how direct air capture (DAC) is evolving from academic research to a commercially viable climate solution — and why it's becoming indispensable in the race to net zero.

With over 15 years of experience building DAC technologies, Christoph shares how Climeworks is scaling the science of carbon removal into a business poised to operate at gigaton scale by 2050. Recognised by TIME as one of the most innovative leaders in climate action, he brings unique insight into the intersection of engineering precision, commercial ambition, and climate urgency.

In this episode, we cover:

What direct air capture is — and why it matters now more than ever

The evolution of DAC from lab-scale prototypes to large-scale plants

Key breakthroughs and cost-reduction strategies shaping the field

The role of corporate partnerships in driving early adoption

Financing climate infrastructure and aligning with impact investors

How Europe’s regulatory leadership is shaping global carbon markets

What it takes to turn climate science into scalable business models

"We’re no longer just inventing technology — we're building the foundations of a trillion-dollar industry.

Why it matters:

Direct air capture is one of the few climate technologies that can physically remove CO₂ from the atmosphere. But making it economically viable requires innovation not just in engineering — but in business models, market design, and policy alignment. This episode dives into all three, offering valuable perspectives for investors, corporates, policymakers, and climate tech founders alike.
