According to the Environmental Ship Index (ESI), three liquefied natural gas (LNG) tankers were the most sustainable ships in 2013. Scored on an index of 2343 ships worldwide, the LNG tankers Al Marrouna, Al Areesh and Al Daayen from Teekay Shipping took the top three spots with a score of 78.3 points.
In a press release from the Port of Rotterdam, the Olympus, a product tanker owned by the Swedish shipping company Sirius Rederi, was the most sustainable ship to arrive in the port in 2013. The tanker occupied fourth position worldwide behind the three LNG tankers, scoring 65.7 points.
This is the third time that the Port Authority, which is one of the initiators of the development of the ESI, has awarded the prize for the most sustainable ship. In 2011 vehicle carrier Morning Carol won the prize and in 2012 it was container ship Cosco Pride.
In 2013 the Port Authority invested approximately €3.5 million in sustainable shipping by sponsoring ESI and the Green Award Foundation. Ships that score highly in this certification system receive incentives valued at approximately 5% of the port tariffs payable.
Environmental Ship Index
The ESI is a certificate issued on 1st January 2011 by the World Port Climate Initiative, on request of the ship owners. The index shows how ships perform environmentally in their emissions of air pollution (NOx and SOx) and CO2. Ports and other nautical service providers all around the world can use the index to reward ships and consequently stimulate sustainable behaviour in shipping. A total of 27 ports and other nautical service providers now award bonuses to ESI ships that attain a certain score.
