Plan Sea is hosted by Wil Burns, Co-Director of the Institute for Responsible Carbon Removal at American University, and Anna Madlener, Senior Manager for monitoring, reporting, and verification (MRV) at the Carbon to Sea Initiative.
As co-hosts, Wil and Anna invite guests to the podcast each episode to discuss potential ocean-based climate solutions, particularly approaches that lead to carbon dioxide removal (CDR) from the atmosphere. The podcast scrutinizes risks and benefits of these options, as well as matters of governance, community engagement, ethics, and politics.
