Brussels, 9 May 2019
On May 3rd, 2019, a few days ahead of the IMO MEPC meetings dedicated to the reduction of greenhouse gas emissions from ships, the EU-funded study on the “Methods and Considerations for the Determination of Greenhouse Gas Emission Reduction Targets for International Shipping” was published by the European Commission.
The study, conducted by CE Delft and UMAS, analysed potential short-term measures included in the International Maritime Organisation (IMO)’s initial strategy and estimated their impact on the reduction of GHG emissions from ships by 2030. The initial IMO strategy commits to improving the carbon intensity of international shipping by at least 40% by 2030 and to reduce the total annual emissions by at least 50% by 2050 (compared to 2008 levels). The specific policy measures that can turn these commitments into practice, considered in the study, are those that could enter into force imminently and help to control GHG emissions over the period between now and 2030.
Various proposals by IMO Member States for emission reduction measures have been assessed in the study, including speed limits and the improvement of ship’s operational efficiency, as well as a shaft power limit.
Most proposals were found to be compatible with the IMO’s objectives provided they are sufficiently strict.
The study also considered options for non-mandatory limits that use existing policy (i.e. Ship Energy Efficiency Management Plan) to incentivise greater efficiency. However, such non-mandatory limits were deemed ineffective as they would reduce GHG emissions by not more than 2% from the expected business-as-usual levels.
The report also analysed the emissions reduction impacts of further increasing the stringency of the Energy Efficiency Design Index (EEDI) regulation. Although these changes would not bring about any significant GHG reductions by 2030, they would achieve more impact in the longer term, the study found.
The Delft study also concluded that developing a standard for ship-shore (port call) communication, or a standard for port incentive schemes as well as creating a framework to incentivise the uptake of renewable fuels would reduce CO2 emissions by less than 1% in 2030.
