The Importance of Ocean CDR in Carbon Removal

Episode 22 is with Dr. Sifang Chen, a Managing Science and Innovation Advisor at Carbon180 and author of the recent white paper, Depending on the Ocean: Research and Policy Priorities for Responsible Ocean Carbon Removal.

We continue to see growing interest in enhancing the ocean's ability to remove and store carbon dioxide. In the last month alone, we've seen the largest investment to date in an ocean-based carbon removal startup, California-based Ebb Carbon.

Soon after, Dalhousie University announced it received CA$154 million - its largest grant ever - from the Canadian government to investigate the ocean's role in climate change, including advancing the science and technology around ocean-based carbon removal. In the face of economic uncertainty, it looks like ocean-based carbon removal isn't going anywhere, but a number of critical questions remain about its future.

Today Na’im speaks with Dr. Sifang Chen from Carbon180 to learn more about ocean carbon removal pathways and how policy can help clarify efficacy, ecosystem impacts, and necessary regulations and governance.

Dr. Chen authored the recently published Carbon180 white paper entitled, Depending on the Ocean: Research and Policy Priorities for Responsible Ocean Carbon Removal. This paper explores how policy can help lower existing uncertainties around ocean carbon removal and offers specific recommendations aimed at clarifying efficacy, ecosystem impacts, and necessary regulations and governance. 

In this episode, Na’im and Sifang discuss:

* Fun facts about the ocean and the immense amount we still don’t know about it;

* Categories and types of ocean carbon removal methods;

* Major challenges facing ocean carbon removal;

* A responsible vs. irresponsible future for ocean carbon removal;

* Policy’s role in ensuring the responsible future; and

* Centering environmental justice in ocean carbon removal.
