By 2023, 78% of logistics companies considered in expect to provide same-day deliveries, and by 2028, 39% of logistics companies anticipate deliveries within a two-hour window. This requires delivery services to become more responsive. Third, consumers increasingly participate in e-commerce with the expectation of shorter delivery times. It is largely expected that COVID-19 will result in a huge and permanent leap forward in e-commerce that otherwise would have taken another 5–10 years. The pandemic, indeed, had a great effect as many people turned to online ordering when local shops closed.

Boosted by the COVID-19 pandemic, it has produced a sharp increase in freight activities and consequently in city traffic. The volume of online shopping worldwide tripled between 20 and is predicted to increase almost five-fold by 2024. Second, e-commerce has steadily grown, and some of the world’s most sophisticated markets can be found in the European Union. A shift in this paradigm has occurred over the course of one century.

In 1950, only one-third of the world’s population lived in cities, while by 2050, the rural population is expected to be only one-third of the total. First, there is a trend in which the population has shifted from rural settlements to urban areas-in 2020, for the first time in history more people lived in urban than rural areas.

In recent years, important trends have put pressure on urban freight transport and have consequently led to increased environmental problems. Thus, this research identifies the operative features of LMD according to the delivery area-city center or peri-urban-and it examines the energy efficiency and the environmental impacts associated with LMD carried out by diesel LDV in both quantitative and qualitative terms. In a second step, this research applies and calibrates an energy demand model to compare the energy efficiency of LDV while delivering along different delivery routes which are local roads, mixed road sections, or crossing residential areas. For one month, 13 carriers from different depots (one located in the city center and the other in the peri-urban area) drove the same LDV model to perform their deliveries, while GPS position, speed, and other engine parameters were recorded instantaneously. Motivated by those results and following the recommendation of the literature stating the need to distinguish between different geographical contexts when planning urban deliveries, a data collection campaign was carried out in the metropolitan area of Madrid, in collaboration with the main logistics company of Spain, Correos. The outputs set a basis for recommendations for using LDV only for delivery routes with less traffic interruptions and foster intermodal solutions. Due to low speeds and frequent start-stops, the efficiency of vehicles in these areas is reduced to a minimum and pollutant emissions increase. Our results highlight the urgency of replacing diesel LDV for deliveries in the city center with no-motorized transport modes and of implementing intermodality to cover deliveries in residential peri-urban areas.

The results show that pedestrian crossings, traffic lights, and traffic congestion reduce the average operating speed by up to 57% in the city center and consequently overall energy efficiency. It enabled calibration and modelling dynamics to calculate fuel consumption and pollutant emissions according to delivery routes. Four different delivery routes typologies were compared, and the drag function of the vehicles was characterized.

Some 242 delivery routes performed by thirteen drivers were recorded for one month, including instantaneous GPS position, speed, and other parameters (7262 km travelled). Based on a real-life case study, this research compares the environmental performance of different delivery routes carried out by Diesel Light-Duty Vehicles (LDV) according to delivery area, city center or peri-urban. Cities are experiencing a process of suburbanization and last-mile delivery has grown, worsening traffic congestion, pollutant emissions, and citizens’ quality of life.
