VM0036 Methodology for Rewetting Drained Temperate Peatlands v1.0
14. Agriculture, Forestry, Land Use
17 July 2017
This methodology outlines procedures to estimate the reduction of net greenhouse gas emissions resulting from project activities implemented to rewet drained peatlands in temperate climatic regions. It allows for the estimation of GHG emissions from drained and rewetted peatlands and also accounts for changes in carbon stocks in selected non-peat carbon pools.
The scope of this methodology is essentially limited to project activities that aim at the rewetting of peatlands that have been drained for forestry, peat extraction or agriculture, but where these activities are not or no longer profitable. Post-rewetting land use is limited to forestry, agriculture, nature conservation/recreation, or activities limited to those aiming at GHG emission reductions, or a combination of these activities.
This methodology uses ground vegetation composition and water table depth as proxies for peatland GHG emissions, known as the ‘GEST’ approach (GEST: Greenhouse gas Emission Site Type).
