This work deals with sustainable development in Graz and examines the university quarter and the Lendviertel. The question is picked out as a central theme, whether an educated society, as it is to be found in the sphere of a university, acts with a longer lasting effect than a society, which was always marked by disparities and unequal development and had therefore less access to education. Besides, the second investigation area is formed by the Lendviertel Graz and by means of the formulation of eight working hypotheses it should be the aim to reveal differences in the conversion of sustainable development between both investigation areas.The theoretical background refers to different topical literature of the called issue and tries to make sustainable behavior tangible and measurable to serve as a basis in the following empiric research. The empiric research mainly exists of a quantitative survey by means of questionnaires and applies to the three target groups „companies“, „restaurants“ and „consumers“ in both investigation areas. After a detailed presentation of the results and a subsequent comparison between both investigation areas, a large part of the working hypothesis is not confirmed at quantitative level, by which a positive answer of the research issue is impossible. A more in-depth discussion presents itself in the fact, that the comparison of the target groups „companies“ and „restaurants“ does only statistically show an unequivocal picture, however, not in a descriptive way. It is not too far fetched, to conclude, that, provoked by a structural change in the former suburbs of Graz, the population promotes sustainable development while companies and restaurants are still lagging behind.
