The Single-Facility Location Problem (SFLP) is one of the most important problems in Logistics and Supply Chain Management. Its significance is crucial for transportation routes and capacity planning, selection of suppliers, and international expansion of enterprises. Concerns regarding the emission of pollutants by transportation vehicles have led to the development of green technologies and sustainable practices.  Within this context we present a model to dynamically integrate an emission factor of CO₂ emissions in the SFLP. This model is proposed in order to consider the pollutant risk factor within the location decision process. Experiments performed on standard FLP instances present a difference in the final location of the facility if the CO₂ factor is considered. This is an important insight to estimate the generation of CO₂ for this kind of decisions and the pollution risks in specific regions.
