Interest in Marine Carbon Dioxide Removal (mCDR) is growing due to its potential to remove significant amounts of CO₂ from the atmosphere, while also offering co-benefits such as mitigating ocean acidification and supporting marine ecosystem health.
This seminar explored why mCDR is attracting attention, the different proposed approaches for mCDR (from ocean alkalinity enhancement to biomass sinking), and the key knowledge gaps that remain around their effectiveness, durability, scalability, and potential environmental and social impacts.
In this edition of the C-SINK Research Seminar Series, Dr. Christopher Pierce also introduced the SEAO2-CDR project, highlighting recent outputs, ongoing activities, and plans for the next year and a half. The session emphasized a holistic perspective, combining scientific, technical, social, and policy considerations to better understand the opportunities, risks, and practical challenges of implementing ocean-based CDR approaches.
Speaker:
- Dr Christopher Pearce, Senior Marine Geoscientist at the National Oceanography Centre (NOC)
Moderator:
- Navraj Singh Ghaleigh, Senior Lecturer in Climate Law at the University of Edinburgh
