Recognizing the problem of global climate change, one of the IPCC’s activities is to support the UN Framework Convention on Climate Change (UNFCCC) through its work on methodologies for national greenhouse gas (GHG) inventories.

In 2014, the IPCC released the 2013 Supplement to the IPCC National Greenhouse Gas Inventory: Wetlands (Wetlands Supplement), which * provides methods for estimating anthropogenic emissions 218and removals of GHGs (CO2, CH4, and N2O) associated with specific activities including aquaculture, salt production, extraction, drainage, rewetting, revegetation and creation, and forest management practice in mangroves (IPCC 2014).

A U.S. case study, applying the guidance in the U.S., illustrates the effect of accounting for management activities directly rather than stock changes associated with Land Use, Land-use Change and Forestry whereby all lands are defined as managed.

The IPCC guidance provided and U.S. case study illustrate how any country can include coastal wetlands as part of their national GHG inventory prepared for the UNFCCC.
