Sustainability Index with Integrated Indicator Dependencies
Sustainability Index with Integrated Indicator Dependencies

Summary/Abstract: Sustainability is a growing concern worldwide. While companies used to focus on financial performance, now the focus has shifted to considering environmental and social performance as well. This trend is not only based on ‘image’, but recent research has proven that a complex approach regarding sustainability could significantly increase a company’s performance. The selection of sustainability indicators as well as the development of sustainability frameworks has been analysed by researchers already. The authors argue that interdependencies exist between different sustainability indicators and concepts. To address this issue, the fuzzy set method has been used and integrated into assessment methods, making it possible to develop a sustainability index which is able to consider the dependencies of the integrated variables. The proposed method can prove that indicator dependencies have a significant influence on the sustainability performance of a company and therefore on its overall performance.
