The 2020 Vision Campaign is the main vehicle for advancing the agenda of Mayors for Peace, a nuclear-weapon-free world by the year 2020. It was initiated on a provisional basis by the Executive Cities of Mayors for Peace at their meeting in Manchester, UK, in October 2003. It was launched under the name 'Emergency Campaign to Ban Nuclear Weapons' in November of that year at the 2nd Citizens Assembly for the Elimination of Nuclear Weapons held in Nagasaki, Japan. In August 2005, the World Conference endorsed continuation of the Campaign under the title of the '2020 Vision Campaign'.
