Summary

In the latest episode of the SPRingBoard Environmental Law Podcast, host Michael Hannaman explores one of the most promising and complex frontiers in climate innovation: Marine Carbon Dioxide Removal (mCDR).

As global emissions continue to rise and the path to limiting warming to 1.5°C narrows, mCDR technologies are emerging as a key mitigation tool. These technologies leverage the ocean's natural carbon cycle to capture and store CO₂, but questions remain about paths forward to large-scale deployment.

To unpack this topic, Michael is joined by Garrett Boudinot (founder and CEO of Vycarb) and Meg Holden (principal at SPR). Together, they examine the science, economics, and legal frameworks underpinning the mCDR field and discuss the social and environmental considerations that guide deployment. What are the key factors for evaluating whether mCDR technologies can truly deliver durable climate benefits? What do early pilot
