The global shipping industry trade association the International Chamber of Shipping (ICS) has said that the total greenhouse gas (GHG) emissions from global maritime transport are estimated to have been more than 20% lower in 2012 than in 2007.
The International Maritime Organization’s (IMO) latest study on the shipping industry’s GHG emissions provided the estimates and the report is set to be considered by its Marine Environment Protection Committee in October.
According to the report, the global shipping industry produced only around 2.2% of the world’s total GHG emissions in 2012 compared to 2.8% in 2007.
During the United Nations Climate Summit in New York, ICS secretary general Peter Hinchliffe said: "The latest IMO study, which uses satellite tracking, suggests there’s been a significant reduction in absolute CO2 emissions from ships due to the introduction of operational efficiency measures across the whole fleet.
"This includes operating at slower speeds, combined with more fuel efficient designs on board the large number of new build vessels that have recently entered the market."
The shipping industry, which is the only sector with mandatory global regulations for the CO2 emissions, aims to reduce CO2 in future through the collaborative effort with the IMO.
"The shipping industry fully recognises that governments expect even greater CO2 efficiency improvements in the future. Given the very high cost of fuel which is soon set to increase by around 50% due to separate new rules on sulphur the industry already has every incentive to deliver this," Hinchliffe added.
