Blue carbon refers to the carbon stored in coastal ecosystems such as mangroves, seagrasses, and salt marshes. These coastal habitats have extensive root systems and dense vegetation that trap and accumulate carbon-rich organic matter. When these ecosystems are undisturbed, they can sequester large amounts of carbon for long periods. However, when these habitats are degraded, much of the stored carbon is released back into the atmosphere as carbon dioxide, contributing to climate change.
Green carbon, on the other hand, refers to the carbon stored in terrestrial ecosystems, primarily in forests and vegetation on land. Forests, in particular, are essential green carbon reservoirs. Efforts to protect and restore green carbon ecosystems, such as afforestation, reforestation, and sustainable land management practices, are vital for maintaining carbon sinks, reducing greenhouse gas emissions, and promoting biodiversity.
