Abstract

In France, the « Grenelle de l’Environnement » has reinforced the role of multi-level local authorities in the setting up of cross-sectoral policies linking climate and energy issues with the capacity to adapt urban systems, buildings and transportation choices. A new generation of Plans called “Territorial Plans for Climate protection and Energy saving “(PCET) has been launched in order to achieve these cross-sectoral policies. Nevertheless, this challenge leads local authorities to develop comprehensive strategies based on a collaborative process between actors dealing with urban changes and transportation choices. What could be methods and instruments used to develop this policy integration?

In order to answer to this question, we will present the first results of an ANR project called “Systemic approach for Climate Energy Plans at the Territory scale: projection for 2050”. This project aims at helping planning the PCETs through a systemic approach focused on the “core” of territory policies composed of the “transportation/buildings/land occupancy” system.

The paper will focus on the two first tasks of the project, which both includes a top-down approach based on the analysis of scientific works and of available expertise (a state of the art task), and a bottom-up approach based on the territory evaluation of local authorities at the city area scale. The following points will be specifically addressed: main factors influencing GHG emissions, interaction between urban form and mobility mechanisms, intersectoral action policies that could be mobilized. The example of the Great Lyon will be given to illustrate each step of the presentation.

Finally, the first draft of a conceptual model of the urban system defined by its sectorial, spatial, and governing interactions will be exposed.
