Managing coastal wetlands is one of the most promising activities to reduce atmospheric greenhouse gases, and it also contributes to meeting the United Nations Sustainable Development Goals. One of the options is through blue carbon projects, in which mangroves, saltmarshes, and seagrass are managed to increase carbon sequestration and reduce greenhouse gas emissions. However, other tidal wetlands align with the characteristics of blue carbon. These wetlands are called tidal freshwater wetlands in the United States, supratidal wetlands in Australia, transitional forests in Southeast Asia, and estuarine forests in South Africa. They have similar or larger potential for atmospheric carbon sequestration and emission reductions than the currently considered blue carbon ecosystems and have been highly exploited. In the present article, we suggest that all wetlands directly or indirectly influenced by tides should be considered blue carbon. Their protection and restoration through carbon offsets could reduce emissions while providing multiple cobenefits, including biodiversity.
管理沿海湿地是减少大气温室气体最具前景的活动之一，它也有助于实现联合国可持续发展目标。其中一个选择是通过蓝碳项目，在该项目中，红树林、盐沼和海草得到管理，以增加碳固存并减少温室气体排放。然而，其他潮汐湿地也符合蓝碳的特征。这些湿地在美国被称为潮汐淡水湿地，在澳大利亚被称为潮上带湿地，在东南亚被称为过渡森林，在南非被称为河口森林。它们在大气碳固存和减排方面具有与目前所考虑的蓝碳生态系统相似或更大的潜力，并且已经被高度开发。在本文中，我们建议所有直接或间接受到潮汐影响的湿地都应被视为蓝碳。通过碳抵消对它们进行保护和恢复可以减少排放，同时提供多种协同效益，包括生物多样性。
