[Shanghai: Explore blue carbon trading accounting and promote multi-scenario application pilots such as zero-carbon islands] On November 10, the Shanghai Municipal Ocean Bureau issued the "Shanghai Municipal Marine Resource Utilization and Ecological Protection "15th Five-Year Plan" Implementation Plan." It mentioned that we should deepen blue carbon research and improve our ability to increase sinks. Develop a pilot work plan for marine carbon sinks. Improve the ability to increase blue carbon sinks, deepen research on blue carbon accounting standards, and promote marine carbon sink accounting pilots; carry out supplementary surveys of salt marsh carbon reserves, explore carbon storage surveys of unvegetated tidal flats, and seabed sediments, and gradually understand the background of ocean carbon reserves; promote monitoring and accounting of carbon sinks in salt marshes and unvegetated tidal flats, and carry out sea-to-air carbon dioxide flux surveys and Revenue and expenditure accounting; quantify the blue carbon sink increase benefits of ecological restoration, conduct an assessment of the effects of marine carbon sinks and biodiversity improvement, and explore pilot projects for marine carbon sink contributions; explore blue carbon trading accounting, and promote multi-scenario application pilots such as zero-carbon islands; study new models of marine ecological protection and restoration oriented to enhance climate resilience and increase marine carbon sink increments.
