Already in 1990 Göteborg City Council decided that the local government committees and city-owned companies should make environmental demands in conjunction with procurement and purchasing. A strategy "The Göteborg Model" was drawn up containing legal requirements, political decisions, tools, information, training and follow-up for implementing green procurement and purchasing. In the Environmental Policy for City of Göteborg is decided that every committee and board must have an environmental management system. City-owned companies and big administrations use the ISO 14001 or EMAS systems. For small city administrations a special EMS was established called the Environmental Diploma. To obtain the diploma a number of criteria must be met, as environmental policy, environmental plan, training, green purchasing, energy efficiency etc.
An English brochure on the Göteborg Model is available in PDF-format.
