Approaches to environmental value analysis of products, processes, and services

The objective of the paper is to present a model for the environmental value analysis (EVA) and its usefulness as tool towards environmental improvement analysis. A new concept called EVA, which focuses on integrating environmental issues with value analysis, is proposed in this paper. The mathematical model of environmental value index (EVI), which is derived from EVA analysis, aims to define the relationship between the importance of the environmental functions and the cost of the functions. The development of EVI provides the basis for generating feasible alternatives, which are performed simultaneously. By determining the EVIs, this approach ensures prioritisation, and thereby predicts a better set of environmental improvement alternatives. Three case studies are used to illustrate the implementation of EVA methodology.
