Özet

International shipping is the most environmentally-friendly and energy efficient mode of mass transport and only a modest contributor to the total volume of atmospheric emissions while moving a considerable part of world trade (90%). Nevertheless, a global approach for further improvements in energy efficiency and emission reduction is needed as sea transport is predicted to continue growing significantly in line with world trade.

Carbon dioxide is the most important GHG emitted by ships. Absent regulations, ship emissions may grow significantly as a result of growth in shipping. The study indicates that by 2020, about 150 million tonnes of annual CO2 reductions are estimated from the introduction of the EEDI for new ships and the SEEMP for all ships in operation, a figure that, by 2030, will increase to 330 million tonnes of CO2 annually. In other words, the average reduction will, in 2020, be approximately 14% and, by 2030, approximately 23%, when compared with business as usual. The reduction measures will also result in a significant saving in fuel costs to the shipping industry, although these savings require deeper investments in more efficient ships and more sophisticated technologies than the business as usual scenario. The annual fuel cost saving estimate gives a staggering average figure of US$50 billion by 2020, and an even more astonishing US$200 billion by 2030.
