The notion of "residential footprint" consists in aggregating the environmental impacts of the dwelling and the environmental impacts of the mobility induced by the home location, over their entire life cycle. This presentation proposes a review of 61 scientific literature documents which aims to present the state-of-the-art in assessing the residential footprint, in a perspective of evaluating the sustainability of residences in the Montreal and Quebec City metropolitan areas. First, the methods to conduct an assessment of the environmental sustainability of residences, as well as data requirements, are outlined. Second, the results of the studies are analyzed and compared. The studies highlight the importance of simultaneously considering housing and daily mobility, both of which account for a significant share of the residential footprint, but also of assessing and differentiating between direct and indirect impacts. They also make it possible to identify the explanatory factors for the different levels of impact, which is essential for implementing equitable measures to reduce households' environmental footprint. Finally, the current gaps in the literature, such as data limitation, incomplete assessment of daily mobility and lack of simultaneous consideration of environmental and monetary impacts, are discussed to guide future work on households' residential footprint.
