Table 4: Global environmental efficiency indices classified by impact category. If the transports considered were to be made in a more sustainable way, the results would be significantly affected. For example, assuming an alternative scenario in which the use of private vehicles represented 45.7% of journeys and 54.3% used public transport [41], the indices shown in Table 5 would be obtained. Similarly, if an alternative scenario was considered in which employees used active means of mobility such as bicycles, when applying 2.1% of the annual kilometres travelled in 2019, reductions in the impact of transport of around 2% would be achieved in all categories (see Table 5). The studied hospital is located in a regional area away from patients and workers who need to use a means of transportation to travel to the hospital. The study led to recommending a location analysis prior to the design and implementation phases for hospitals [42]. Planned hospitals should analyse their future locations while considering, among other factors, the distance to the residences of their potential patients and employees.
