Abstract

This letter welcomes the global data synthesis of carbon storage and dynamics provided by Mason et al. (2023). However, their estimate of the climate benefits of saltmarsh restoration would seem too high, by around an order of magnitude, with many associated uncertainties. The suitability of using saltmarsh restoration for carbon offsets is therefore questionable.
