2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories: Wetlands

This technical document extends the content of the 2006 IPCC Guidelines for National Greenhouse Gas Inventories and provides updated information reflecting scientific advances, including updating of emission factors for wetlands. It covers inland organic soils and wetlands on mineral soils, coastal wetlands including mangrove forests, tidal marshes and seagrass meadows and constructed wetlands for wastewater treatment. The coverage of the 2006 IPCC Guidelines on wetlands was restricted to peatlands drained and managed for peat extraction, conversion to flooded lands, and limited guidance for drained organic soils.
