Madrid is testing a new approach to urban logistics and sustainable delivery by shifting parcel transport underground. With e‑commerce growth driving up to 20% of city traffic, officials and delivery firms are exploring how the Madrid Metro can ease congestion and cut emissions.

If successful, the model could offer a template for other European cities seeking greener last-mile delivery solutions while keeping streets clear above ground.
