Abstract: With the aim of providing a supplement to 2006 IPCC Guidelines for National Greenhouse Gas Inventories to fill in the gaps within it on the methodological guidance for the inventory of anthropogenic emissions and removals of greenhouse gases (GHG) from wetlands, 2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories: Wetlands was published in February 2014. On the basis of effect of human activity and deliberation again on the definition of wetlands, the supplement provided methods for the estimation of GHG emissions and removals from wetlands under drainage and rewetting. The supplement also presented a methodology of estimation of GHG emissions and removals from coastal wetlands and constructed wetlands for wastewater treatment by human activities. The publication of the supplement provides a comprehensive methodological guidance for inventory compilers to estimate the GHG emissions and removals from wetlands under human’s activities. Nevertheless, by the limitation from the scientific development and academic literature availability, some methodological guidance for the estimation of GHG emissions from wetlands, such as the loss of particulate organic carbon from drainage, emission of organic carbon from external ecosystems to the wetlands by rewetting, is still needed to be further developed.
