Global Ocean Negative Carbon Emissions

International commitments currently advocate for reductions in CO₂ emissions through responsible human interventions, which are essential to prevent a potential temperature rise of 2°C within the next 20-30 years. The United Nations Ocean Decade-endorsed program - Global Ocean Negative Carbon Emissions (ONCE) aims to harness various ocean carbon sequestration mechanisms to maximize the potential for atmospheric carbon dioxide removal, known as marine Carbon Dioxide Removal (mCDR). This session serves as an international forum for dialogue among scientists, entrepreneurs, and policymakers, focusing on the utilization of marine environments to bolster climate change mitigation strategies. The session is designed to offer insights into the research, application, and management of mCDR, providing vital information for decision-makers tasked with constructing climate mitigation and adaptation initiatives. Furthermore, the session aspires to catalyze urgent collaboration by underscoring significant research gaps and proposing actionable policy recommendations.
