The Diplomatic Conference held (October 1-5, 2001) by the International Maritime Organization (IMO) in London adopted the Draft Convention prepared by The Marine Environmental Protection Committee (MEPC) of IMO for the "Control of Harmful Anti-fouling Systems for Ships." The Convention has been developed to immediately ban the use of Tributyltin (TBT) globally in antifouling paints to "protect the marine environment". The ban on TBT has come about because TBT has detrimental effects on non-target marine organisms. In November 1999, IMO agreed that a Treaty be developed by the MEPC to ensure a ban on the application of TBT based antifouling paints by January 1, 2003, and a total ban on the use of TBT by January 1, 2008.
