Cargo drones vs trucks in the mid-mile: An integrated cost, reliability, and emissions analysis for sustainable logistics
Abstract
Purpose. This paper investigates whether cargo drones can serve as a viable, sustainable alternative to diesel trucks in mid-mile freight logistics, an operational segment linking regional hubs and fulfilment points that remains dependent on fossil-fuel trucking despite mounting cost, emissions, and regulatory pressures. Methodology. An integrated, scenario-based analytical framework compares drones and trucks across cost, carbon emissions, and operational reliability. The framework combines modular cost decompositions, first-principles emissions accounting, and a simplified additive reliability model, parameterised with consolidated secondary data on energy prices, grid carbon intensity, and weather-driven unmanned aerial vehicle performance across five representative operational scenarios. Results. Drones deliver lower per-kilometre operating costs than trucks in most high-demand and high-fuel-price scenarios and consistently achieve 80-90 percent lower emissions across all scenarios. Reliability is the binding constraint: drone availability drops sharply under adverse weather, while trucks maintain stable performance across nearly all conditions. Theoretical contribution. The study extends the drone-logistics literature, previously concentrated on last-mile, single-dimension assessments, by offering one of the first integrated, multi-criteria comparative frameworks for mid-mile operations and by showing that climatic and grid-decarbonisation factors, not technology maturity alone, determine modal competitiveness. Practical implications. The findings support hybrid truck-drone network design, weather-adaptive routing, and prioritised regulatory pathways for Beyond Visual Line of Sight corridors in climatically stable, decarbonising regions, providing operators and policymakers with a decision-support basis for sustainable freight modal choice.
