Six shipping carriers have become the inaugural participants in the Port of Los Angeles Environmental Ship Index (ESI). The ESI is an international clean air program that rewards ocean carriers for bringing their newest and cleanest vessels to the Port. Developed through the International Association of Ports & Harbors’ World Ports Climate Initiative, the ESI program is the first of its kind in North America and the Pacific Rim. Shipping carriers Evergreen, Hamburg Süd North America, Inc., Hapag-Lloyd AG, Maersk Line, Nippon Yusen Kaisha and Yang Ming have registered for the global program and will begin receiving incentives later this year.
