Last-mile mobility describes transportation activity occurring near the end of a route—often involving delivery vans, motorcycles, and e-bikes that operate in dense neighborhoods and around workplaces. The public health relevance of last-mile transport lies primarily in its contribution to air pollution exposure and, secondarily, in how active or electric mobility can shape safety and chronic disease risk. A central topic in this context is emissions reduction: transitioning from internal combustion engines to electric vehicles (EVs) used for delivery workloads can lower tailpipe emissions such as nitrogen oxides (NOx) and particulate matter (PM). NOx contributes to ground-level ozone formation and can irritate the respiratory tract, aggravating asthma and chronic obstructive pulmonary disease (COPD). Particulate matter—especially fine (PM2.5) and ultrafine particles—penetrates deep into lung tissue and can drive systemic inflammation.
From a mechanistic standpoint, combustion processes emit pollutants that interact with airway epithelium. Oxidative stress and inflammatory signaling (including pathways involving cytokines such as IL-6 and TNF-α) can worsen airway hyperresponsiveness. Inhaled particles can also impair mucociliary clearance and increase susceptibility to respiratory infections. For COPD, repeated exposure accelerates decline in lung function by promoting chronic inflammation, increasing the frequency and severity of exacerbations. For asthma, pollutant exposure is linked to increased symptom burden, emergency visits, and medication escalation.
EVs reduce direct tailpipe emissions because they do not combust fuel onsite. While upstream electricity generation can create emissions, the net air quality benefit depends on the local electricity mix, grid decarbonization trends, and utilization patterns. Even before full grid transition, EV deployment can reduce localized pollutants where delivery fleets operate, a key factor for community exposure. Additionally, electric drivetrains can lower some noise-related stressors; while noise is not the same as air pollution, both can influence cardiopulmonary outcomes through stress physiology and sleep disruption.
Last-mile delivery also includes traffic micro-environments. Frequent stops, idling, and maneuvering in crowded streets elevate near-road concentrations. Electing EVs for these segments can specifically target these high-exposure moments. Environmental health literature often links near-road pollution to higher asthma prevalence in children, more severe COPD outcomes in adults, and increased cardiovascular events due to shared inflammatory pathways. Fine particles can promote endothelial dysfunction and a prothrombotic state, which is why air pollution reduction is considered both respiratory and cardiovascular preventive medicine.
To evaluate impacts, public health researchers typically use cohort studies, time-series analyses, and quasi-experimental designs such as difference-in-differences following fleet electrification. Outcomes include hospital admissions for asthma or COPD, all-cause mortality, lung function metrics, and symptom days. Several studies across urban settings have found that reductions in traffic-related pollutants correlate with improved respiratory health indicators. However, effect sizes vary depending on baseline air quality, population vulnerability, compliance, and the degree of electrification (e.g., conversion of motorcycles vs. larger vans).
Equity is an important dimension. Communities near distribution corridors may face disproportionate exposure because of higher baseline pollution levels and limited healthcare access. Electrifying delivery fleets can therefore function as an environmental justice intervention, potentially reducing health disparities. In practice, implementation should be paired with monitoring—using fixed-site and mobile sensors—to verify pollutant decreases and identify any rebound effects from charging-related energy use.
Beyond air quality, last-mile mobility innovations can support safer commuting patterns when paired with broader transportation planning. Safer streets and more predictable traffic can reduce injury risk, which indirectly affects respiratory health through trauma-related complications and healthcare system strain. For respiratory health specifically, however, the strongest evidence pathway remains pollutant reduction.
For clinicians and public health practitioners, the key takeaway is that emissions reduction in last-mile logistics can serve as a modifiable environmental determinant of health. Patients with asthma or COPD may benefit most in the short term as pollutant peaks decline, and in the long term through reduced cumulative inflammatory burden. Organizations deploying EV leasing programs for last-mile delivery can frame their impact using measurable indicators: NOx/PM reductions, ambient concentration monitoring, and downstream health endpoints such as respiratory exacerbations.
Ultimately, electrifying last-mile delivery is not a stand-alone cure, but it is a scalable prevention strategy grounded in well-established toxicology and epidemiology. When combined with clean electricity generation, strong grid planning, and local air monitoring, EV adoption for last-mile mobility can plausibly reduce respiratory morbidity and improve population-level cardiopulmonary outcomes.
