IMO has already adopted mandatory technical and operational measures to improve the energy efficiency of ships and reduce GHG emissions, including the energy Efficiency Design Index (EEDI) for new ships and the Ship Energy Efficiency Management Plan (SEEMP) for all ships of 400 GT and above. IMO has further, adopted mandatory technical and operational measures to improve the energy efficiency of ships and reduce GHG emissions, which aims, as a matter of urgency, to decarbonise international shipping in this century.
Proposals for a technical approach included an Energy Efficiency Existing Ship Index (EEXI), which could require ships to meet set energy efficiency requirements after the measure taking effect. Other technical proposals relate to mandatory power limitation on Operational approaches would include focusing on strengthening the ship energy efficiency management plan, as required in SEEMP. This include proposals for mandatory carbon intensity reduction targets. Operational proposals also include measures to optimize speed for the voyage. Proposals to limit ship speed were also discussed.
The initial IMO strategy lists a number of measures which could also be considered to further reduce emissions and help achieve the targets in the strategy, in particular 40% reduction of carbon intensity from shipping by 2030.
