As a typical low-carbon transportation mode, inland navigation needs less land, produces less pollution, consumes less energy but carries more goods. In order to scientifically evaluate green performance of inland navigation, using the method of LCIA to analyse input and output inventories, the paper constructs the green degree evaluation index system of inland navigation, quantifies the indices with fuzzy analytic hierarchy process (F-AHP) , and uses linear weighted sum method to calculate the final comprehensive evaluation. The results show that inland navigation has some green properties, but can’t meet the requirement of China’s lowcarbon society, so the paper puts forward some advanced measures based on the basic attribute and environment attribute.
