This report addresses issues related to developing a GHG offsets quantification methodology and performance standard for tidal wetlands in the United States. The foci of the report are questions related to additionality, performance standards, permanence, GHG quantification, market interest, and other issues related to developing a GHG offset methodology as part of the California Climate Action Registry (CCAR) offsets program. Another focus will be on the emerging guidance of quantifying sequestration rates, and the related uncertainties with the existing approaches. Two or three representative example states (including California) are used to investigate the options for setting performance standards, and other issues.
