"This paper is mainly concerned with the metamorphoses in the European cities and the initiatives of the European Community institutions, notably the Commission, for policy responses, in the light of the Green Paper on the Urban Environment (27 June 1990) and the following workshops and conferences. It will consider metamorphoses in the Urban Euroscape*, in relation to: - The Global Environment After years of environment degradation in cities (because of urban growth, traffic growth, increased international trade, etc.) important achievements are reported at the European scale witnessing increasing awareness of public bodies and citizens for environmentally friendly cities and the implementation of policies improving the city's metabolism. A better balance between what the city takes in (raw material) and what it takes out (products and waste) is required at the European level, and waste starts being considered as a resource and not as a nuisance. The principle "Polluter pays for Pollution" is being replaced by "Potential Polluter pays for Pollution Prevention".- Social Integration Even in the most wealthy European cities, there are islands of social exclusion, very often coinciding with islands of environmental degradation, delinquency and crime. Both in the older industrialised cities of the North and the newly urbanised centres in the south, there are groups and sectors increasingly marginalised from mainstream society. New policies of European solidarity and partnerships incorporate socio-environmental elements (improved transportation environment, social housing environment, employment related to new environmental activities) to reverse the downward spiral of two speed urban societies and revitalise the built Euroscape. New urban patterns are being conceived for the creation of a more equalitarian city and the long-run propensity for revitalisation in Europe.- Land Use Management There is a European search for the sustainable city of the 21st century. The mix and Integration of urban functions, after decades of rigid zoning seems to be the cornerstone of many future developments and land use management the main instrument to achieve this structural change. Land use, as an investment attracting factor and urban added value generator is closely linked to the emerging identity of the European Cities (each of them unique) and the strategic visions for their future.- Eurocities and Euroregions The point will be made on the new role of cities as nucleous for regions, in a new multiterritorial and pluri-cultural Europe. Cities and regions are the new actors, emerging at the European scene, but, in this scene, the ill-equipped and less-developed areas will have increasing difficulties to meet the challenges and share the benefits of the Single Market.- The Technocity The Eurocities are main producers and consumers of new technologies. Their innovation activities are influenced by many internal and external factors. The knowledge basis of the cities is questioned and there is a renewed debate about the ambiguous role of new technologies, as a one dimensional solution to urban problems."
