海洋负排放国际大科学计划项目成果在COP30“中国角”发布

Core Viewpoint - The ONCE initiative, led by Chinese scientists, aims to provide a comprehensive framework for ocean carbon sequestration, integrating various mechanisms to support global climate governance [1][2]. Group 1: ONCE Initiative Overview - The ONCE initiative is part of the United Nations' "Decade of Ocean Science" framework and involves 79 teams from 33 countries [1]. - The initiative combines four major ocean carbon sink mechanisms, creating a "four-pump integration" theoretical system [1]. - ONCE proposes a "triple pragmatic" approach that is fair, reasonable, and executable, aiming to translate scientific findings into policy [1]. Group 2: International Collaboration and Support - ONCE has signed cooperation agreements with marine institutions in countries like Brazil and Chile [1]. - The initiative is seen as a crucial step in bridging the gap between data and decision-making, providing scientific basis for effective ocean carbon storage regulations [2]. - The leadership of Chinese scientists in advocating for ONCE is highlighted as a strong example of international cooperation [2].
