Abstract
In 1994, 'the Committee on Trade and Environment' was created within the World Trade Organisation. Meeting three times a year, and composed of all WTO members plus some observers, its creation testifies of a need to take into account environmental issues into the formation of an international trade policy. Ever since the creation of the GATT in 1945, to most recent times, and the creation of WTO, free trade has been recognised as the main goal to be achieved regarding international trade, as it sustains economic growth. Therefore, it is true that the multiple exchanges has boosted the economy all world.
