This week on Cleaning Up, Michael Liebreich sits down with carbon removal insider Robert Höglund, CEO of Marginal Carbon, co-founder of CDR.fyi and architect of MilkyWire’s Climate Transformation Fund, for a deep dive into what’s working and what’s not in carbon dioxide removal and corporate climate action.
Drawing on five years of hands-on experimentation funding everything from biochar to direct air capture and policy advocacy, Robert challenges the dominant “speed and scale” narrative. Instead, he makes the case for a new phase: prove and learn.
Together, Michael and Robert unpack why the highest-impact climate interventions are often the least measurable, why corporate net-zero targets are more conditional than we admit, and what it will actually take to make carbon removal credible, scalable, and worth paying for.
