Smaller ships have different efficiency requirements for each phase.
Phase II: ships built between 20 will have to improve their energy efficiency by 15 and 20%, depending on the ship type.Phase I: an overall 10% improvement target in vessel energy efficiency applies to new ships built between 20.Standards are compared to the baseline, set as the average efficiency of ships built between 1999-2009. How much more fuel efficient will EEDI ships have to be, and by when?ĭifferent classes and sizes of ships will have different standards to meet. Read our questions and answers on the IMO’s EEDI. The index requires new ships to become more energy efficient, with standards that will be made increasingly more stringent over time. It applies to (almost) all new ships and entered into force in 2013. The IMO’s Energy Efficiency Design Index (EEDI), approved in July 2011, is the first globally-binding design standard aimed at abating climate change from shipping. On their own, technical measures or measures that remove market barriers will not improve carbon intensity sufficiently to meet the global goal for reducing energy intensity of shipping of 40% by 2030.ĭespite these plans and many successive rounds of negotiations, the IMO has so far failed to adopt reduction measures to set the maritime sector on a pathway compatible with the temperature goals of the Paris Agreement. CE Delft has analysed the impact of the proposed short-term measures on emissions and concludes that only with measures that change operational practices (for example, the vessel speed) the 2030 target can be met. The candidate short-term measures, include strengthening the energy efficiency requirements for existing ships (EEDI), speed and other technical and operational measures. This is to be achieved by an agreed set of short, medium and long measures which are the subject of ongoing negotiations. It was agreed that carbon intensity of international shipping should decline with reductions in CO2 emissions per transport work, as an average across international shipping, by at least 40% by 2030, pursuing efforts towards 70% by 2050, compared to 2008. In April 2018 the IMO agreed a draft greenhouse gas strategy for shipping requiring the shipping sector to reduce its emissions by at least 50% by 2050 compared to 2008’ while pursuing efforts towards phasing them out as soon as possible. What action is the IMO taking to address climate change? Parties are required to establish ‘economy-wide’ emission reduction targets, and shipping is clearly a key part of the economy. Unlike Kyoto, which had specific emission targets only for developed countries, the Paris agreement requires all parties to address all emissions. Until the Paris agreement was finalised at the end of 2015, the major climate agreement in force was the Kyoto Protocol which tasked developed countries to work through the IMO to cut emissions. Is shipping included in the Paris Agreement? Currently there are no regulations controlling black carbon emissions from shipping.
#Transportation carbon emissions driver
Black carbon accounts for 21% of CO2-equivalent emissions from ships, making it the second most important driver of shipping’s climate impacts after carbon dioxide. The highest amounts of black carbon particles are produced by ships burning heavy fuel oil. Shipping also contributes to climate change through emissions of Black Carbon, tiny black particles, produced by combustion of marine fuel. Under a business-as-usual scenario and if other sectors of the economy reduce emissions to keep the global temperature increase below 2 degrees Celsius, shipping could represent some 10% of global GHG emissions by 2050.
#Transportation carbon emissions update
The latest update to the study by CE Delft projects shipping emissions to increase by up to 120% by 2050 if other sectors decarbonise successfully. The Third IMO GHG Study (2014) estimated that for the period 2007-2012, shipping emitted about 1,000 Mt CO2 per year, equaling approximately 3.1% of annual global CO2 emissions. What is the impact of shipping on climate change?
