Recent regulatory evolutions gave the opportunity to professionals and academics from the health, urban planning and environment sectors–within a working group–to conduct in-depth research at a national level on health challenges in the field of EIA procedure and urban planning. This work resulted in the publication of a guide aimed at all actors involved in the urban planning decision process, which has now become a national reference document. Among the key findings of this project, three main concrete outputs caught our attention: a reference framework for Healthy Urban Planning (HUP); an all-encompassing tool for analysing urban planning projects ‘with a health lens’; an operational tool aimed at French regional health agencies (ARS) to help them formulate their health statements within the framework of the EIA regulatory procedure applied to urban development projects. This paper reviews the process of co-constructing the guide with special attention paid to the ARS tool, present the key findings and outputs and discuss the potential of the EIA process in promoting HUP in the current French context
