This study aims to conduct an energy-based greenhouse gas (GHG) inventory of port operations at PT X, Lampung Province, Indonesia. The research evaluates direct (Scope 1) and indirect (Scope 2) emission sources to provide a quantitative overview of the port’s carbon footprint and support the development of strategic decarbonization measures. The study employed the GHG Protocol using an energy consumption-based approach covering the period from January to December 2023. Secondary data were obtained from company reports, including diesel fuel and electricity consumption. Emission calculations were performed using activity data and standardized emission factors from the Intergovernmental Panel on Climate Change (IPCC) and the Indonesian Ministry of Environment and Forestry (KLHK). The results show that the total annual GHG emissions from PT X amount to 6,287.74 tons of CO₂, consisting of 2,850.96 tons from direct emissions and 3,436.78 tons from indirect emissions. The higher proportion of indirect emissions (54.66%) indicates a strong dependence on electricity supplied by PLN, which still relies heavily on fossil fuels. Electrification of heavy equipment and the adoption of energy-efficient LED lighting have effectively reduced direct emissions. The findings emphasize the importance of clean energy transition and integration of GHG inventories into environmental management documents. This study provides essential insights for achieving national decarbonization goals and developing sustainable low-carbon ports in Indonesia.
