Today, we have two guests, Peter Minor, Director of Science and Innovation at Carbon180; and Jack Andreasen, Policy Manager for Carbon Management at Breakthrough Energy. Peter and Jack are two of the world’s foremost experts in the world on carbon dioxide removal, or CDR as it's called in climate circles. They and their respective organizations influence public policy, support critical technology research and development, and offer various other forms of support for the burgeoning field of CDR.

In this conversation, we're focused almost exclusively on ambient carbon dioxide removal and not on point source carbon capture, which is a separate but related technology focused on directly capturing emissions from hard-to-abate industrial applications like concrete, steel, and fossil fuel extraction. Ambient carbon dioxide removal (CDR) instead seeks to remove diffuse CO2 from the atmosphere directly via multiple methodologies, of which the most widely pictured method is direct air capture, or DAC, which looks like oversized fans that extract CO2 from the air. In addition, we also touch on a few biology-related CDR technologies like biochar that seek to lock biologically produced carbon up before it can become atmospheric.

There's so much to unpack in this one. Cody, Peter and Jack talk about policy tailwinds for CDR, the categories and methodologies, commercial adoption progress and challenges, how and why buyers approach the space today, and some of the speed bumps CDR will undoubtedly encounter as it scales, including but not limited to fraud and false claims. Challenges aside, it's an exciting time in this space. CDR is still very nascent and very wide open, but it also feels light years further along than just a few years ago.
