In view of an increased environmental consciousness of the city-population, the European cities are faced with the task to improve the urban bioclimatic situation perceptibly. Consequently, the immission of dust, noise and other stress factors have to be restrained significantly. At the same time, urbanity has to be preserved and developed. Both aims (urban ecology and urbanity) are subject to strong economic and social restrictions. By that, the urban environmental policy comes into numerous and partly serious conflicts of aims. The aim of these investigations is the reduction of environmental pollution in urban regions. Especially the atmospheric dust pollution will be reduced by construction of new plants greenery on roofs of buildings. We illustrate a solution of principle (as an example the district Kreuzberg of Berlin and the centre of Madrid). The most important matter is to fix the aims which have to be approximated by the multicriterial optimization procedure. In many cases th e aims stand in contradictions in relation to other aims. A procedure for S02-reduction in East-Germany is illustrated. It supplies connections between pollutant emission of point sources, immission (concentration/deposition) at receptor points or grid elements. The user is provided with a tool for evaluation emission reduction strategies by scenario technique and by optimization facilities in order to calculate optimal timing of control strategies and minimal needed immission reduction. A possibility (waveform-relaxation- procedure) for model reduction of non-linear dynamical systems is given.
