Urbanization and low-carbon growth pathways : Modeling the interactions between energy and real estate prices

International audienceThis presentation proposes a framework for thinking the role of urban dynamics in the transition towards low-carbon societies. This is done by capturing both the driving effect of macroeconomic trends on urban dynamics and, conversely, the consequences of urban/regional location choices on mobility needs, investments and production possibilities affecting macroeconomic trajectories and carbon emissions. In an integrated description of global macroeconomic trajectories and location decisions in multiple agglomerations, we reassess the cost of climate policies when considering not only their global dimensions captured by carbon and energy prices, but also their local determinants associated to the spatial organization in urban areas. Among the latter, we focus more specifically on the interplay between constrained mobility needs corresponding to daily commuting distances, investment constraints due to housing and transport infrastructure deployment and land prices capturing the competition for different locations within agglomerations
