Comparison of the implementation of MFA, EE I-O and process LCA on different cities of Southern Europe for their urban metabolism study
Résumé
The percentage of global population living in urban areas increases and could rise up to 70% of the total in 2050. These areas consume large amounts of materials and energy to
maintain their activities. In the last years, they have promoted sustainable development initiatives to reduce the environmental impacts generated by their material and energy
metabolisms.
This research takes place within the framework of the Ecotech Sudoe Project. This project contributes to build an industrial ecology network between member-state academics in
southern Europe. It consists in studying urban metabolisms of three Southern European cities (Aveiro in Portugal, Barcelona in Spain and Marseille in France) and their environmental
impacts, to contribute to the development and testing of environmental accounting and impact assessment methodologies. It aims at 1/ comparing the elements resulting from the use
of Material Flow Analysis, Extended Environmental Input-Output analysis and Process Life Cycle Assessment and 2/ identifying their potential articulation in the production of a
territorial diagnosis. On the basis of these results, a comparative analysis of the three cities is performed in order to highlight the levers and opportunities on the three territories
