图面解释一个蓝碳地区如何进行碳封存

蓝碳是气候变化缓解领域的一个概念，定义为“是指由海洋和沿海湿地所吸收并储存的碳”。 [1] : 2220 能够吸收蓝碳的区域被称为蓝碳栖息地，通常意指例如潮间带、红树林和多海草之浅海区域等。 [1] : 2220 

蓝碳栖息地在碳封存中能发挥许多作用。这些生态系统可以在减缓气候变化并减少地球的碳总量。但当蓝碳生态系统退化或消失时，所吸收的碳会重新释放至大气中，进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 属于生物碳固定。

目前学术界仍在进行更多蓝碳的研究，希望借此进一步减少地球总碳量。 [3]然而，想要将蓝碳作为去除二氧化碳，是否能够成为永久解决地球碳量问题的方法，目前尚有许多争议待厘清。 [4] [3] [5]
