Sustainable environment indicators and possibilities of their aggregation by

Abstract: There are dozens of sets of indicators, which try to resolve the problem of sustainable environment development on different levels from local to global. Currently, there are two approaches under development: policy based and capital approach. This article engages evaluation of sustainable environment on regional level, where the number of indicators had to be, for purposes of strategic decision-making, limited only to the most important ones. It is possible to solve the problem by Petri nets. The result is example of aggregation for group of indicators, which would allow us to give information to regional development management in form usable for superior decision-making
