ESI is an international clean ship indexing program developed through the International Association of Ports and Harbors' World Ports Climate Initiative that seeks international collaboration among ports and shipping lines to reduce air emissions and greenhouse gases, while promoting sustainability. Operators earn the ESI incentive by using cleaner technology and practices that reduce emissions beyond the regulatory requirements set by the International Maritime Organization (IMO). A point system resulting in an ESI score for each vessel is used to qualify for the incentive. To obtain an ESI score, the operator must upload the following information to the ESI website:
NOx Points: Rated power, and rated engine speed (rpm) and actual NOx emissions (g/kWH) for the vessel’s main and auxiliary engines. (This information is contained in the vessel’s EIAPP Certificate.)
SOx Points: Amount and fuel sulfur content per bunkering event for heavy fuel oil, marine gas oil (MGO)/marine diesel oil (MDO) above 1 percent sulfur, less than or equal to 0.5 to greater than 0.1 percent sulfur and less than 0.1 percent sulfur (This information is contained in the vessel’s bunker delivery notes). Confirmation that the vessel is Onshore Power Supply (OPS) ready or capable of plugging into shoreside electrical power also known as Alternative Maritime Power® (AMP®).
CO2 Points:Vessel operator reports fuel consumption and nautical miles sailed.
The greater the ESI score, the larger the incentive. Each OGV is eligible for an incentive grant on a per call basis to the Port of Los Angeles based on the following ESI scores:
- 40-49: $750 per call
- 50 or greater: $2,500 per call
The Port of Los Angeles will pay incentives to vessel operators for ship calls only after the date they have registered for ESI.
