The horrifying Seveso incident of 1976 made the European Community members realize the consequences of improper treatment of hazardous substances and, in turn, paved the way for stricter environmental regulations. In 1976, the European Economic Community (EEC) issued a directive establishing a single set of rules for cosmetics. The scope of the amended directive covers all chemicals manufactured within EEC states and intended for export to foreign destinations. The OECD, in cooperation with the United Nations and the EEC, has been able to restrict the manufacture and use of certain chemicals in all 24 of the OECD member nations. The Waigani Convention is modeled on the Basel Convention and is also strongly related to the London Convention of 1972. It constitutes the regional implementation of the international hazardous waste control regime. There are, however, some differences between the two conventions; the Waigani Convention covers radioactive wastes and extends to the Exclusive Economic Zone unlike the Basel Convention.
