MARPOL Annex VI – Resolution MEPC.203(62)

This resolution, adopted in July 2011, was a significant step in addressing air pollution from ships. It introduced regulations aimed at improving the energy efficiency of ships, specifically through:

1. Energy Efficiency Existing Ship Index (EEXI): This index measures a ship’s energy efficiency relative to a baseline. Existing ships must comply with certain EEXI requirements by specific deadlines.
2. Ship Energy Efficiency Management Plan (SEEMP): All ships must have a SEEMP in place, outlining measures to improve their energy efficiency and reduce greenhouse gas emissions.

Key Points:

• Applies to: All ships of 400 gross tonnage and above.
• EEDI (Energy Efficiency Design Index): New ships built after July 2013 must meet specific EEDI requirements to limit their carbon footprint.
• SEEMP: This plan details how a ship will achieve and maintain energy efficiency, including measures like hull design optimization, engine efficiency improvements, and operational practices.
• DCS (Data Collection System): Ships must collect and report data on fuel oil consumption and other relevant parameters to monitor and verify compliance.

Goal:

The overarching goal of these regulations is to reduce greenhouse gas emissions from international shipping, contributing to efforts to mitigate climate change.

Impact:

MEPC.203(62) has been a driving force in the shipping industry’s transition towards more energy-efficient practices. It has led to the development of new technologies and operational strategies that reduce fuel consumption and emissions.

Additional Developments:

Since the adoption of MEPC.203(62), the IMO has continued to strengthen its regulations on air pollution from ships. This includes further amendments to Annex VI, such as the introduction of a Carbon Intensity Indicator (CII) for existing ships and the development of a strategy to reduce greenhouse gas emissions from international shipping.
