Good Practice Information

The Environmental Ship Index (ESI) identifies seagoing ships that perform better in reducing air emissions than required by the current emission standards of the International Maritime Organization. The Environmental Ship Index (ESI) is based on the amount of nitrogen oxide (NOx), sulphur oxide (SOx) and greenhouse gas that is released by a ship. ESI is therefore a good indication of the environmental performance of ocean going vessels and will assist in identifying clean ships in a general way. The index can be used by ports to reward ships when they participate in the ESI and to promote clean ships, but can also be used by shippers and ship-owners as their own promotional instrument. The programme is completely voluntary and helps the global port community to assume its role in improving the maritime and port environment.
This initiative has been launched by the World Ports Climate Initiative (WPCI, www.wpci.nl). This is a commitment of fifty-five world’s key ports to reduce their greenhouse gas emissions (GHG) while continuing their role as transportation and economic centres. Its objectives are based on the World Ports Climate Declaration (adopted in July 2008 in Rotterdam). Hamburg Port Authority (HPA), member of the International Association of Ports and Harbours and beneficiary of PORT INTEGRATION (PI), introduced ESI to the PI partners (and beyond) at the first PI workshop in Ancona in November 2010.

Evidence of success

At the moment there are 5 ports which established ESI in their port dues. 9 other ports have shown interest in joining the initiative. All in all, 519 ships of 57 different ship owner companies worldwide have joined the initiative. Hamburg has implemented the ESI in the port dues since 1 July 2011, applying a scaling on different ESI-points resulting in different Port Due amount. Meaning that in the Port of Hamburg different port fees discounts can be granted depends on the amount of ESI-Score (e.g. ESI score 20 up to < 25 = 0.5% discount; ESI score >50 = 10% discount; ESI score <20 = no discount). Hamburg had fruitful discussions with ship-owner companies. As a result, a lot of companies joined the database with their ships, others will follow.
However, in the WPCI working group the discussions on the ESI calculation methods are still on-going. Discussion points regard the inclusion of other systems such as green award, for example, as well as issues related to the national regulations in ports (San Pedro Bay, Northamerican ECA…). It is planned to gradually change the calculation method. The aim of these discussions is also to gather proposals for the improvement of the website and to make it more users friendly.
All participating ports will have the possibility to exchange experience regarding the implementation of the ESI, the Handling and new calculation methods. Participating ports will have to adapt their port fee regulations accordingly. These models should enhance the transition to the calculation of port dues based on environmental aspects.
