'Blue carbon' ecosystems highlighted at forum as key to tackling climate change

Scientists and policymakers from home and abroad have called for stronger cooperation to leverage the ocean's potential in combating climate change through "blue carbon" ecosystems.

They made the suggestion on Friday when attending the 2025 Hainan Blue Carbon Forum, hosted by the Hainan International Blue Carbon Research Center. The event highlighted coastal ecosystems such as mangroves, seagrass meadows and salt tidal marshes as powerful natural carbon sinks.

While exchanging ideas on the topics, these experts also stressed the need for global standards to measure, verify and trade blue carbon credits to integrate them effectively into climate strategies.
