As global warming intensifies, innovative carbon dioxide removal (CDR) technologies are increasingly recognized as critical and marine CDR (mCDR) or ocean negative carbon emission (ONCE) approaches have shown great potential for using the ocean reservoirs for long term carbon sequestration. On the other hand, such technologies need to be developed and applied with a strong sense of responsibility, transparency, equitability, and inclusiveness, to ensure minimal negative impacts on the marine environment. This town hall event aims to bring together scientists, engineers, private sector leaders, governmental officials, and philanthropists to discuss the current state of mCDR research and explore strategies to implement and scale ONCE technologies in alignment with global climate goals and to safeguard marine ecosystem services. In particular, the town hall session will address the growing interest in Ocean Alkalinity Enhancement (OAE), and the need for responsible research, transparent data sharing, and international coordination to ensure that these technologies are implemented equitably with appropriate monitoring, reporting and verification (MRV) put into place. This exchange of ideas is crucial for advancing mCDR research and ONCE technologies, prioritizing both scientific rigor and environmental protection. By leveraging public-private partnerships and fostering cross-sectoral collaboration, the event will help accelerate the development and responsible research into and deployment of mCDR, enhancing its potential to contribute to global climate resilience that can be sustained by an equitable and robust carbon market.

Town Hall 12 will be coordinated with TM 23 – 'Government-focused principles for ethical and effective marine carbon dioxide removal development and deployment'. It also links with the Science Session T2-5 Carbon dioxide removal approaches: effectiveness, durability, risks, as well as monitoring, reporting and verification.
