More than 10000 different types of ship ply the waters of Bangladesh all year round, but the performance of these ships in terms of CO2 emission is not known and regulations related to energy efficiency of inland waterway ships remain nonexistent. This paper attempts to assess the present situation of inland class vessels in terms of Energy Efficiency Design Index (EEDI). With the use of a developed database of inland vessels in Bangladesh, EEDI reference lines for different types of inland vessels in Bangladesh were established and then compared with those of other countries. The present EEDI of existing inland vessels was investigated. Results indicate that most of the existing vessels do not meet the current EEDI baseline. Hence, new guidelines are necessary to achieve EEDI compliance in the near future. Some recommendations were proposed for improving CO2 emissions, with the socio-economic and technical factors in Bangladesh taken into consideration.
