Adaptation of the LCA framework to support land use planning policies

Adaptation du cadre méthodologique de l'ACV afin d'aider les politiques d'aménagement du territoire

Résumé

Since the implementation of the European Directive on strategic environmental assessment (2001), local authorities are in charge of carrying studies on the environmental impacts of land use planning policies. However, they are facing with a lack of standardized approaches to perform such assessement. Methodological developments are therefore needed for the environmental assessment of spatial planning policies adopted on a territory. In order to achieve this, different kinds of tools and methods can be used. Among them, LCA has been identified as a promising tool as it has the ability to avoid burden shifting between environmental impacts as well as between life cycle stages. Yet, no study which performs the environmental assessement of a territory as a whole has been reported. The aim of this presentation is twofold. Firstly, the main methodological bottlenecks which can partlty explain the lack of applications of LCA to territories have been identified and discussed, i.e., (i) functional unit definition, (ii) boundary selection, (iii) data collection and (iv) the refinement of LCIA indicators in order to provide useful information for land planning policies. Secondly, for each bottleneck, proposals have been made to overcome it and to provide a general framework adapted to land planning issues. One of the main adaptations relies on the functional unit definition. The territory (defined by its geographical boundaries) and its related land planning scenario will now be considered as the reference flow. The adapted framework will hence deliver two kinds of indicators (calculated outputs), the environmental impacts and a set of services provided by the territory. This adapted framework offers a new perspective on the issue of the environmental assessment of land planning policies by proposing a global approach which include all the activities located on a territory, avoiding burden shifting between territories, prioritizing environmental issues and identifying the most polluting activities on a territorial context which could need a complemetary analysis (e.g., environmental risk analysis).
