Williamson and Gattuso (2022): Carbon removal using coastal blue carbon ecosystems is uncertain and unreliable, with questionable climatic cost-effectiveness
Phillip Williamson and Jean-Pierre Gattuso IN: Front. Clim., 28 July 2022, Sec. Negative Emission Technologies, https://doi.org/10.3389/fclim.2022.853666
The focus here is on assessing the feasibility of achieving quantified and secure carbon removal (negative emissions) through the restoration of coastal vegetation. Seven issues that affect the reliability of carbon accounting for this approach are considered: high variability in carbon burial rates; errors in determining carbon burial rates; lateral carbon transport; fluxes of methane and nitrous oxide; carbonate formation and dissolution; vulnerability to future climate change; and vulnerability to non-climatic factors.
