Product Life Cycle (PLC) is defined as the duration of a product; beginning with extraction and proceeds through material processing, construction, uses and its ultimate disposal. This research caters until the construction stage. PLC is an objective procedure used to evaluate environmental impacts associated with the exchanges in entire life cycle; from the extraction of raw materials until the processes of construction. The main objective of this research is to analyze the environmental impact of selected small craft along their life cycle by using Life Cycle Assessment (LCA). The level of impact on specific categories impact is determined by using Life Cycle Assessment (LCA) method. In this study, analysis was conducted onto 13m landing craft based on the data obtained from a field study at selected shipyard. The primary environmental impacts are acidification, eutrophication, global warming, ozone depletion and photochemical ozone production. The results show that the emission of CO2, NOx, SOx, NMVOC and PM, as well as the consumption of diesel oil, are major environmental load items contributing to environmental impact during the life cycle of the craft.
