UN Body Nears Agreeing Ship Pollutant Limits UK: April 4, 2008 LONDON - The world's top maritime body has tentatively agreed new sulphur limits for ship fuels that will slash air pollutants, but cost the oil and ship industry dear, an industry source close to the talks said on Thursday. At a major UN International Maritime Organisation (IMO) meeting in London this week countries gathered to thrash out how best to reduce harmful ship pollutants, like sulphur dioxide, and tackle climate changing gases.
