What makes Clean Shipping Index unique for ports is that you can differentiate your port fees, e.g. to vessels with onshore power supply, based on third party verified information. There is a clear difference in Clean Shipping Index between vessels’ non-verified and certified scores, due to different reasons. The associated costs can be seen as increasing the barrier of entering the index, but the return of investment for vessels with high environmental performance is in general short. In many cases the cost is negligible, taking into consideration that the certificate has a three year validity.
Choosing Clean Shipping Index will also mean that you will take into consideration the methodology’s holistic approach, where water & waste and chemicals are included – something that is unique for CSI. This enables you to e.g. focus on rebates for vessels with non-toxic antifouling.
