藍碳

蓝碳是气候变化缓解领域的一个概念，定義為「是指由海洋和沿海濕地所吸收並儲存的碳」。 ^[1] ^:2220能夠吸收藍碳的區域被稱為藍碳棲息地，通常意指例如潮間帶、红树林和多海草之淺海區域等。 ^[1] ^:2220

藍碳棲息地在碳封存中能发挥許多作用。这些生态系统可以在减缓气候变化並減少地球的碳總量。但当蓝碳生态系统退化或消失时，所吸收的碳會重新释放至大气中，進而增加温室气体排放。 ^[1] ^:2220

蓝碳管理方法属于“基于海洋的生物二氧化碳去除（CDR）方法”范畴。 ^[2] ^:764屬於生物碳固定。

目前學術界仍在進行更多藍碳的研究，希望藉此進一步減少地球總碳量。 ^[3]然而，想要將藍碳作为去除二氧化碳，是否能夠成為永久解決地球碳量問題的方法，目前尚有許多爭議待釐清。 ^[4] ^[3] ^[5]
