Carbon footprint of fishing activities is an utmost important study at present for mitigation of climate change. It is a simplified form of life cycle assessment (LCA) which measured total amount of carbon dioxide emissions. Assessment of emission and energy utilization in fishing were neglected earlier and very minimal information are available in Indian context. The present study analyzed the fuel consumption, energy utilized and carbon emission rate of trawlers from north-west coast of India. Efficiency of different categories of trawlers i.e., single-day (SD), multi-day small (MDS), multi-day medium (MDM) and multi-day large (MDL) trawlers was estimated. SD trawlers were found to be most efficient followed by MDM, MDL and MDS. Single-day fishing was significantly different from multi-day fishing in terms of fuel efficiency, energy intensity and carbon emission rate. A total of 1769 trawlers were operated from Versova …
