We are pleased to invite you to join the upcoming C-SINK research seminar “Navigating the Sea of Uncertainty Around Marine Carbon Dioxide Removal (mCDR)”.
Date: Thursday, October 2nd, 2025
Time: 12:00 – 13:00 CEST
Location: Zoom – Please register here. After registering, you will receive a confirmation email containing information about joining the meeting.
Marine Carbon Dioxide Removal (mCDR) is emerging as a potential component of the portfolio of solutions needed to address climate change. Interest in these approaches is growing due to their 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 will explore why mCDR is attracting attention, the different proposed approaches (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.
Dr. Christopher Pearce will also introduce the SEAO2-CDR project, highlighting recent outputs, ongoing activities, and plans for the next year and a half. The session will emphasize 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
