Environmental Ship Index

Environmental Ship Index

As part of its promotion of sustainable shipping, WPCI has developed the Environmental Ship Index (ESI). Ships fuelled by LNG generally achieve a high ESI score. Around the world, 30 ports typically provide 5-10% discounts on harbour dues or another financial incentive, contributing to a positive business case for operators. Over 2,300 ships have been registered to qualify for port discounts and/or incentives.
