Ⅰ. Background and Objectives of the Research
1. Necessity and Objectives of the Research
oAchieving carbon neutrality through natural carbon sequestration is becoming increasingly urgent as global climate change worsens.
ㅇUtilizing carbon sinks such as forests with biomass and soil carbon storages and wetlands is critical to achieving carbon neutrality.
-Previous research on carbon sinks has mainly focused on forests, and there has been little research on wetlands, especially inland wetlands, in the domestic context.
-Accordingly, the country-specific emission factors and methods reflecting the national circumstance for wetland in the national GHGs inventory have not been developed yet.

oBasic research on leveraging wetlands in the pursuit of carbon neutrality is necessary.
ㅇIn order to fully utilize wetlands as carbon sinks, it is vital to first establish the groundwork upon which such a system can be operated. This would include, for example, a prescribed method for calculating greenhouse gas emissions.
-There is a need to explore ways to promote wetland creation and utilization as carbon sinks.



Ⅱ. Status and Ecosystem Services of Wetlands
1. Status of Wetlands
o Types and Classification of Wetlands
ㅇ The IPCC defines wetlands as land that is submerged in water either year-round or temporarily, and categorizes wetlands into peatlands, flooded lands, and other types of wetlands.
ㅇ The cadastral statistics, which are used when calculating national GHG inventory, classifies wetlands into ditch, reservoir, and fish farm in South Korea.
-In the field, wetlands with veget
