"Climate crisis" is listed as one of the three major global crises threatening the future of humanity. The massive emissions of greenhouse gases, represented by carbon dioxide (CO₂), are considered the main cause. As the impacts of climate change continue to expand globally, the United Nations environment programme has issued a warning that only an urgent system-wide transformation can avoid a climate catastrophe. Ocean as the largest active carbon reservoir on Earth, has become the hope for humanity to address climate change. "Ocean negative carbon emissions" symbolizes a significant shift from passive response to proactive action addressing the global climate crisis.

The purpose of the Global ONCE programme is to provide rational, reasonable, and legitimate ocean-based solutions to climate change. The programme has officially endorsed by the United Nations Decade of Ocean Science for Sustainable Development (2021-2030). In November 2023, Open Science Conference will be hosted by the Global ONCE programme and co-hosted by Xiamen University. The conference aims to further explore regional and global ocean negative emission implementation plans aligned with the Global ONCE programme. Scientist with multidisciplinary expertise, policymakers, and citizens shared the same vision from around the world will gather to discuss cutting-edge topics related to the Global ONCE approach. We warmly welcome all participants to join us.
