Established in 2009 by Le Havre and seven other European ports, the ESI today covers more than 38 ports and 4000 merchant vessels worldwide.

Of 12 shipping lines recognised at the December 2015 ceremony, WWL was one of only two RoRo carriers that ranked highly enough to qualify.

The ESI was established in an effort to encourage ship owners to reduce atmospheric emissions from ships and encourage them to voluntarily go beyond statutory requirements in order to improve air quality and the environment. Vessels are measured according to engine performance, onboard equipment and fuel quality.

The award ceremony took place at the Port of Le Havre and was well attended by shipping companies, customers, freight forwarders and members of the trade press.
