A new study reveals that bottom trawling in European waters is estimated to cost society up to £9.5 billion annually, primarily due to the release of CO2 from the disturbence of seabed sediments. The study marks a significant moment as it is the first of its kind to calculate the comprehensive economic cost of bottom trawling. The carbon emissions from this fishing method are said to be on the same scale as global aviation, highlighting major environmental implications. Despite the economic benefits in terms of jobs and food provision, the costs associated with climate change and the destruction of marine habitats far outweigh these advantages. Restricting this practice within marine protected areas is suggested as a step toward mitigating these effects, with small-scale, sustainable fishing practices offered as viable alternatives. Furthermore, the study calls attention to the role of government subsidies in supporting this industry, proposing a redirection of these funds to support a more sustainable transition for the fishing sector. While some European countries have moved toward banning or restricting bottom trawling in protected areas, a comprehensive enforcement and phased elimination of this practice by EU member states by 2030 remain a goal yet to be fully realized.
