Following a week-long environmental meeting, the International Maritime Organization said March 5 that the world’s shipping industry was unable to make headway on developing market based measures to reduce greenhouse gas emissions. The United Nations agency did make progress in other areas, including the adoption of guidelines to support next year’s mandatory measures to improve ships’ energy efficiency, on the recycling of ships, and final approval on a number of ballast waster management systems. International shipping accounts for 870 MMT CO2, about 2.7 percent of total global CO2. The next debate will occur during the 64th session, scheduled for October 1-5.
