This paper presents an application of a multi-attribute aggregation methodology to the construction of a sustainability index. Sustainability is a multi-faceted issue, in which synergies or conflicts may arise among the different components, thus making it a complex concept to which multi attribute methods can be applied. This paper addresses the development of the FEEM Sustainability Index (FEEM SI), a composite index including 19 different indicators grouped in the three classical pillars of sustainability ‒economic, social and environmental. We present the relevance of multi-attribute aggregation methodologies when dealing with such complex concepts and provide an aggregation methodology used for this case study, the Choquet-integral aggregation. In particular, since this methodology requires the assignment of weights on indicators and their coalitions, an ad hoc questionnaire is implemented to assess the importance of sustainability indicators through expert elicitation. After computing consensus weights for the Choquet-integral aggregation procedure the overall sustainability index, the FEEM SI is calculated. This paper also conducts robustness analysis and discusses the main implications of the aggregation methodology used.
