The concept of ‘sustainable retail development’ implies that retail centres should serve their communities economically and socially, while not degrading local environments. However, existing evidence shows that shopping malls often negatively impact both the core and peripheries of city regions from environmental, social, and economic perspectives. This paper adapts commuting data to estimate the hypothetical shopping-related emissions associated with travelling to-and-from retail centres. We perform this analysis at the Small Area level for Ireland’s five major city regions. Our results suggest that the environmental degradation from retail centres increases as distances from urban cores increase.
