Assessment of some indicators within an impact

Abstract

A thorough presentation and discussion of principles for the selection and building of indicators was given in Chapter 4. Chapter 4 also discussed the role of different kinds of criteria for the selection or building of indicators. A procedure applicable for the selection or building of environmental indicators for transport was arrived at in section 4.4.2. The procedure, including the use of ten criteria listed in Table 25, is brought further in the present Chapter 5. This is done by presenting how the suggested procedure can be applied to seven of the chains of causalities described in Annex 6: direct toxicity of air pollutants (section 5.1), natural habitat fragmentation (section 5.2), non-renewable resource use (section 5.3), loss of cultural heritage due to land take (section 5.4), noise as annoyance to humans (section 5.5), greenhouse effect (section 5.6), and waste (section 5.7). The seven chains have been selected so as to − be of value for European-level policy makers − be of value for national government policy makers − be of value for regional planners and policy makers − be of value for researchers and other academics − be pedagogic − include causality chains that are qualitatively different − include chains that are well described and well known For three of the chains, the application of the different steps of the procedure has been outlined. For six of the chains, examples of existing indicators for a limited number of chain steps are presented and discussed. The chapter also illustrates how the procedure could be applied for the building of an indicator where there is a lack of indicators (section 5.4
