Decarbonization of Marine Fuels—The Future of Shipping
Abstract
:1. Introduction
2. Carbon Dioxide Emission from Shipping
- The Energy Efficiency Design Index (EEDI) for newbuilds mandating up to 30% improvement in design performance depending on ship type and size in comparison with 2013 (year of requirement introduction) [13];
- The Ship Energy Efficiency Management Plan (SEEMP) for all ships above 400 GT in operation [14]; and
- The Fuel Oil Consumption Data Collection System (DCS) mandating annual reporting of carbon dioxide emissions, and other activity data and ship particulars for all ships above 5000 GT.
- The Energy Efficiency Design Index for Existing Ships (EEXI) with expected entry into force on 1 January 2023;
- The Carbon Intensity Indicator (CII) (as AER (Annual Emission Rating) in grams of CO2 per deadweight-mile) with rating scheme from A to E calculated every year for all cargo and cruise ships above 5000 GT; and
- A strengthening of the SEEMP with mandatory content achieving the CII targets.
