MANILA, Philippines — The global shipping fleet will cut fuel use to reduce carbon dioxide emissions by an average 13 percent in 2020, saving around $50 billion in costs, according to an International Maritime Organization study.
New energy-efficiency rules for ships, to come into effect in January 2013, were passed by the United Nation’s shipping agency in July. They aim to lower emission by as much as 20 percent for new ships by 2020 and 30 percent five years later. Existing ships need to have plans showing how they will cut fuel use with no targets set.
The rules will lower carbon emissions from shipping by 152 million metric tons to 951 million tons by 2020, a study commissioned by the IMO to assess the impact of regulations found. Energy-efficient designs for new ships, as well as sailing at lower speeds or making technical upgrades to existing vessels would curb emissions, according to the study.
Shipping won’t be able to reduce emissions below levels measured in 2010 over time because growth in world trade outweighs the cuts expected to be achieved, the study found.
International shipping accounted for 870 million tons or 2.7 percent of global output in 2007 and is the most efficient form of mass transport, according to a 2009 IMO study.
Curbs will apply to bulk carriers that haul minerals and grains, crude and product tankers, container ships that transport manufactured goods in boxes, refrigerated and general cargo ships, gas carriers, and combination carriers.
