DHL wants to improve parcel deliveries in Germany with a 15-minute advance notification before a driver arrives, according to Deutsche Post DHL chief Frank Appel. The long-serving CEO also backed the idea of a CO2 emission tax to promote ‘green growth’ and supported the idea of consolidated last-mile deliveries in city centres by just one contracted logistics company in a wide-ranging interview with the Bonn-based General Anzeiger and the Rheinische Post regional newspaper. In response to increasing criticism and complaints about DHL’s delivery times in Germany as volumes grow, Appel promised improvements including better customer notification in future. “We will significantly improve the accuracy of (delivery time) predictions for parcels,” he declared.
