Optimal retail location and CO₂ emissions

In this article, the <italic>p</italic>-median model is used to find the location of retail stores that minimizes CO₂ emissions from consumer travel. The optimal location is then compared with the existing retail location, and the excess CO₂ emissions compared with the optimal solution is calculated. The results show that by using the environmentally optimal location, CO₂ emissions from consumer travel could be reduced by approximately 22%.
