Abstract: Tuna fishing is a fishing activity with high fuel use intensity (FUI) that contributes significantly to greenhouse gas emissions. In order to support Indonesia's commitment to the Paris Agreement, efforts to reduce emissions are needed across all sectors, including fisheries. Mapping the carbon footprint (CFP) of tuna fishing activities is essential in identifying key emission points and formulating targeted strategies. This research aims to calculate and compare FUI and CFP from tuna fishing using handline, purse seine, troll line, and longline in several Indonesian fishing ports. Data were obtained through an inventory of previous studies and port statistics. Results showed that FUI ranged from 0.18-2.32 kg/kg, with the highest value for tuna longlines at Palabuhanratu Fishing Port and the lowest for purse seines at Kutaraja Fishing Port. Estimated CFP of tuna ranged from 0.06-1.72 kgCO2eq/kg, with the highest value for tuna longlines at Nizam Zachman Fishing Port and the lowest for purse seines at Kutaraja Fishing Port. Based on each vessel's gear type, size, or location, no specific pattern was found for either FUI or CFP. This research confirms that FUI is influenced by fuel consumption and catch, while tuna CFP is primarily influenced by FUI and composition of the tuna catch.
