This methodology outlines procedures to quantify net greenhouse gas emission reductions and removals resulting from project activities implemented to restore tidal wetlands. Such activities include creating and/or managing the conditions required for healthy, sustainable wetland ecosystems.
Projects applying this methodology are expected to generate greenhouse gas emission reductions and removals primarily by increasing both biomass and autochthonous soil organic carbon. Projects applying this methodology may be developed anywhere in the world.
