Abstract Coastal wetlands are hotspots of carbon sequestration, and their conservation restoration can help to mitigate climate change. However, there remains uncertainty on when where coastal wetland most effectively act as natural solutions (NCS). Here, we synthesize current understanding illustrate the requirements for benefit climate, discuss potential paths forward that address key uncertainties impeding implementation. To be effective NCS, projects will accrue cooling benefits would not occur without management action (additionality), implementable (feasibility) persist over management-relevant timeframes (permanence). Several issues add if these minimum met. First, serve both a landscape source sink other habitats, increasing in additionality. Second, potentially migrate outside project footprints they respond sea-level rise, permanence. first two issues, system-wide approach may necessary, rather than basing only changes within boundaries. Third, need NCS function decadal timescales means methane responses necessary include planning monitoring. Finally, is how much data required justify action. We summarize make binary decision whether net from action, noting more readily available quantify magnitude crediting purposes. By reducing uncertainty, implemented at scale significantly contribute addressing crisis.
