ABSTRACT- Many sets of sustainable development indicators currently exist. They all share the aim to describe the state of the various dimensions (economic, social, institutional, and environmental) of sustainable development. EPSILON brings this strategy one step further, evaluating dimensions per se but also interactions between them: It models the links between consumption, production of goods and pollution and also adds, in parallel, the exchange between regions. This is a critical issue when working at the regional level since the smaller the area the larger the importance of imports and exports. In addition, since regions are more specialized than countries, it is of importance to know how a region is benefiting from the others (importing goods and not the related pollution for example) or coping with the burden of others (transfer of air pollutions for example). The presentation will show the use of the model starting from a case study on selected regions and showing the exchanges of goods and the transfer of pollutants at regional and national levels. Two types of interactions are studied: From a socio-economic aspect, both production and consumption issues are included, through and extended Input-Output framework and a Life Cycle Assessment of the consumption basket. Long range pollutants transfers are incorporated thanks to the EMEP model.
Key words: Pollutants transfers, Input-Output, consumption
