Aggregation of Environmental Data

Abstract

The paper deals with environmental data measuring and related problems. The main problem is undefined relation. On one hand, there are subjects which produce harmful substances or activities; on the other hand there are harmed subjects. The first subjects are known, those are the owners of the activities which cause damage while the other subjects are unknown. This leads to the fact that damage quantification and their value are practically not exactly measurable. It is, however, possible to work with assumptions and solve partial problems. The mathematical view sees it as defining scalar representatives of the comparative indicators such as prices. The paper draws attention to the fact that the literature often presents incorrect conception, e.g. the price level is defined by basic price index. The base has an assigned unit level. The indexes in general are, however, indicators of changes.
