Port of Los Angeles Pioneers International Clean Ship Incentive Program in North America and the Pacific Rim

The Port of Los Angeles became the first seaport in North America and the Pacific Rim to adopt an international clean air program that rewards ocean carriers for bringing their newest and cleanest vessels to the Port. The Los Angeles Board of Harbor Commissioners formally approved an Environmental Ship Index (ESI) program to take effect July 1.

The ESI is a web-based tool developed by the World Ports Climate Initiative (WPCI), a project of the International Association of Ports and Harbors (IAPH). The ESI program, already underway at several major European ports, offers immediate and significant clean air benefits by rewarding vessel operators for voluntary engine, fuel and technology enhancements that reduce emissions from ships beyond the regulatory environmental standards set by the International Maritime Organization (IMO).

Ship emissions are the single-largest source of air pollution from port-related operations. While diesel particulate matter (DPM) and sulfur oxide (SO_x) emissions from ships calling at the Port of Los Angeles decreased 68 percent and 74 percent, respectively, between 2005 and 2010, Los Angeles sees the ESI as another strong step to encourage the building and deployment of cleaner-burning ships in the TransPacific trade lane.

The Port of Los Angeles developed its ESI with input from the Pacific Merchant Shipping Association and other stakeholders. Its program also conforms to the San Pedro Bay Clean Ports Air Action Plan, which sets specific bay-wide targets for near-term pollution reduction through 2014 and long-term objectives through 2023.
