This paper calculates that fisheries account for about 1.2% of global oil consumption and directly emit over 130 million tonnes of CO2 into the atmosphere.

This paper explores the scale of energy consumed by most segments of the Norwegian fishing fleet for gadoid fish and for parts of the pelagic fleet for the period 1980–2005. Possible means of reducing energy use and emissions are discussed including changing operational strategies, hull forms and the use of alternative energy carriers. The use of liquefied natural gas is reported to be the best short term solution which could give a reduction of the discharge of NOx of 85% and CO2 of about 20%.

This report gives valuable data on energy use in a range of fisheries types across the world, showing the energy intensity of fish production. It shows large variability across sectors and within a sector, between locations and fishing methods.

This report is a good starting point as it includes an overview of impacts of climate change on fisheries as well as adaptation and mitigation measures in the fisheries sector which can be taken, focusing on less industrialised nations. The mitigation section is comprehensive and finds that there may be synergies between emission reductions, energy savings and responsible fisheries. It goes on to propose this list of useful policy recommendations which could contribute to all these goals:

India's greenhouse gas (GHG) emissions rose by 58 per cent between 1994 and 2007 with the energy sector contributing over half of the emissions, according to a report published by the Indian Government’s Minstry of Environment and Forests.
