In order to support transition policies at the level of the Arc lemanique territory, "LOCAL: Lifestyles and Carbon impact in the Arc Lemanique territory" is a project aiming to quantify the energy and carbon footprint of its inhabitants' lifestyle and their socio-economic determinants by jointly analyzing the different spheres of activity and their interactions. The project is based on an interdisciplinary methodology at the interface of environmental economics, urban sociology, and industrial ecology and is part of a broader study based on the survey "Panel lemanique de suivi de la durabilite des pratiques". Hence, LOCAL is an important step for local authorities towards a contextual understanding of regional carbon emissions and for the advancement of research on the interrelated dynamics of individual change and territorial policies in the face of climate change.
