Abstract

Blue carbon refers to the carbon captured and stored by marine and coastal ecosystems, such as mangroves, seagrasses, and salt marshes. These ecosystems play an integral role in mitigating climate change by sequestering significant amounts of atmospheric carbon dioxide and providing a range of ecological benefits. Blue carbon sequestration represents a critical natural solution to addressing the global climate crisis, particularly as anthropogenic greenhouse gas emissions continue to rise. This article explores the mechanisms and contributions of blue carbon ecosystems, highlights research methodologies, examines results from recent studies, and discusses the potential and challenges of leveraging blue carbon for climate mitigation.
