The monetisation of trawling avoidance ... should be approached with caution until the region-specific non-market value for tropical areas is robust; the social cost of carbon framework provides the most defensible economic argument for protection.

Industrial shrimp trawling depletes seabed blue carbon, releasing CO₂ into the atmosphere as that carbon breaks down. Fuel-intensive vessels add further emissions. This brief weighs contested global estimates of trawling-driven CO₂ release, highlights the tropical evidence gap, and sets out spatial closures, gear upgrades, and indicators to guide management.
