Environmental groups are calling on the fishing industry to take urgent steps to decarbonise the sector. They say they have calculated that the UK fleet emits the same carbon dioxide as 110,000 homes every year.
A new report says fishing practices need to change to protect carbon stored in the sea bed.
Fishing leaders say efforts to conserve fish stocks show they have already come a long way.
The report has been co-written by WWF, the Marine Conservation Society and the RSPB.
