For instance in the energy and environmental fields, IDA is widely used to disentangle and separate changes in energy consumption, energy intensity or greenhouse gases (GHG) emissions. Although a large number of IDA methods have been reported in the literature over the last decades, there is still no consensus as to which is the preferred one. We aim at developing a framework to determine which IDA method is the most suitable for a given situation. This scheme should avoid four main drawbacks that are frequently come across in the literature. First, such comparative study should integrate a wide range of methods, including the most recent ones. Second, it should be conducted according to a thorough and well-organized set of criteria. Third, since method selection can be problem specific, the characteristics of the situation should be considered and taken into account. Finally the collection of results and opinions should be synthesized using an elaborated and objective tool. After reviewing the literature on decomposition methodologies, we come up with a tree of alternatives that constitutes a scheme of investigation for the comparison of them and a guideline for this study. We also detail thirteen different formulae, classify them into three clusters and provide a table that summarizes the formulae. The research is performed through a three stage process. First two case studies test the impact of using different indicators and methodologies. This provides some useful insights on the behavior and on the ease of application of the decomposition methods. V Summary Second, we review the literature related to comparative studies, use the advancements made in economics and eventually come up with a set of criteria that integrates both methodological and empirical elements. It includes the size of the residual term if any (factor reversal test), the time reversal test, the proportionality property, the usability of both additive and multiplicative approaches, the existence of a direct and simple relation between both approaches, the applicability, computational ease, transparency, adaptability and ease of formulation of the method. Third, we propose a framework to deal with the complication induced by the trade-offs between criteria. We use a combination of both Analytical Hierarchy Process (AHP) and Quality Function Deployment (QFD) that has some interesting properties. It appears that five methods seem to have better overall results than the others: Logarithmic Mean Divisia Index (LMDI) and LMDI 2, then Fisher, Mean Rate of Change Index (MRCI) and Marshall-Edgeworth. For a particular situation, the framework shall lead to the most suitable decomposition method, which should be one of the five above mentioned. As to time treatment, fixed base year decompositions lead to results that are not satisfying and should be avoided when possible.
