European Bottom Trawling: The Hidden Cost of Carbon Emissions and Bycatch

A new study reveals that bottom trawling in European waters causes significant environmental damage and economic loss. By dragging heavy nets across the seafloor, these vessels release stored carbon dioxide and kill vast amounts of non-target marine life, creating a massive societal cost. Research indicates that these activities cost up to $18.5 billion annually. The study highlights a critical failure in regulation, as a quarter of this destructive fishing occurs within Marine Protected Areas, undermining climate goals and ocean biodiversity.

The fact that 25 percent of this happens in Marine Protected Areas is the real story. It shows a total disconnect between designating a zone as protected and actually enforcing the rules. Policy intent is useless without a monitoring mechanism that has teeth.

Exactly. If the MPAs are just lines on a map, they are not protecting anything. The report mentions an 18.5 billion dollar cost, but I wonder how much of that is actually attributed to the carbon release versus the loss of biodiversity.

The carbon numbers here are interesting, but I want to see the methodology on how they calculate the CO2 release from sediment disturbance. Is this a one time release or a long term shift in the seabed's capacity to store carbon?

It is likely a mix of both. The physical destruction of the habitat means the ocean floor can't recover its sequestration ability quickly. It turns a carbon sink into a source.

Interesting shift toward creel fishing mentioned here. Moving from industrial nets to baited pots is a practical way to cut bycatch, but the scale of the industrial fleet makes the transition a massive economic hurdle for the industry.
