RDE496 Assessment of Tier 1 and Tier 2 emission factors for saltmarsh

The IPCC's 2013 Wetland Supplement (Chapter 4, IPCC, 2014) has set out the methodological guidance for the quantification and accounting of greenhouse gas (GHG) emissions and removals associated with the management (e.g., drainage, rewetting, extraction of sediment) of coastal areas, specifically mangroves, tidal marshes, and seagrass meadows. However, there are major gaps in our current understanding regarding GHG emissions of these ecosystems, as well as the source of carbon within accumulated sediments. The rece...
