The article “Mobility scenarios and their impact on air quality in the city of Naples” is now available online. It investigates the impact of different mobility scenarios on urban air quality in the Naples metropolitan area, using an advanced high-resolution modelling system.

The research quantitatively assesses the contribution of road traffic and maritime activities to atmospheric pollutant concentrations (NO₂, PM₂.₅, PM₁₀, and SO₂), by simulating intervention scenarios such as port electrification (cold ironing) and vehicle fleet renewal.

The results show that:

• the targeted road-traffic interventions, particularly the removal of the most polluting vehicles, are the most effective in reducing NO₂ and particulate matter, with the greatest benefits observed in high-traffic urban areas and along major road corridors;

• the electrification of ships at berth leads to reductions in both emissions and concentrations of NO₂, SO₂, and particulate matter, with the most pronounced effects in port areas and surrounding zones;

• the adoption of integrated mobility policies can effectively contribute to improve air quality in complex coastal urban environments.
