What goes up, must come down.

A year ago, the Nordic Carbon Removal Association (NCRA) didn't exist. Today, it has 37 members, a seat at the table in Brussels, and a founding story that reads a lot like a startup's. In this episode of What Goes Up Must Come Down, Klimate's Simon sat down with Valter Selén, co-founder and Secretary General of the NCRA, and Alexander Mäkelä, Chief Policy Officer at Carbon Gap and NCRA co-founder, to talk through how the association came together, where Nordic carbon dioxide removal (CDR) stands today, and what's needed to turn the region's potential into real, permanent removal capacity.

In this episode of What Goes Up Must Come Down, Simon spoke with Kurt Jager Lykke, Head of Business DK at INEOS Energy and head of Project Greensand. Kurt has led the commercial side of Greensand since its inception and took over as project head in 2024. Their conversation covers the project's origins, the organisations that made it possible, and what the carbon dioxide removal (CDR) sector can take from it.

In this episode of What Goes Up Must Come Down, Simon is joined by Stacy Kauk, Chief Science Officer at Isometric, a carbon registry. Together, they explore the challenges of scaling a market where buyers do not fully trust what they are buying, suppliers struggle to finance what they are building, and the science is still catching up with the ambition.

In this episode of What Goes Up Must Come Down, Simon is joined by Berend De Haas, co-founder of Carboneers, a distributed biochar supplier in India and Ghana. Together, they explore the challenges of running biochar projects across multiple countries, the impact of Carboneers’ initiatives, and what the future holds for biochar as a carbon removal solution.

In this episode of What Goes Up Must Come Down, Simon is joined by Marian Krüger, founder of Remove, a nonprofit supporting carbon removal startups worldwide. Together, they explore the motivations behind why companies buy carbon removal credits and how compliance will shape the sector’s future.
