摘要：The combustion of fossil fuels is considered a major cause of climate change, which is why the reduction of emissions has become a key goal of the Paris climate agreement. Coherent monitoring of the energy profle of fshing vessels through an energy audit can efectively identify sources of inefciency, allowing for the deployment of well-informed and cost-efcient remedial interventions. We applied energy audits to a test feet of ten vessels, representing three typical Mediterranean trawl fsheries: midwater pair trawl, bottom otter trawl, and Rapido beam trawl. Overall, these fsheries use approximately 2.9 litres of fuel per kilogram of landed fsh, but the fuel consumption rate varies widely according to gear type and vessel size. This amount of fuel burned from capture to landing generates approximately 7.6 kg ∙CO2/ kg fsh on average. Minimising impacts and energy consumption throughout the product chain may be another essential element needed to reduce the environmental costs of fshing. Our results provided a set of recognised benchmarks that can be used for monitoring progress in this feld.
