DPD delivers every parcel in Hamburg's city using emission-free vehicles. This is why we have joined forces with the cities of Lisbon, Paris and Madrid in a pilot project using next generation sensors, our delivery vehicles and our depots measure air pollution by particular matter (PM_2.5) in real time. The comprehensive data has enabled the authorities in Lisbon to create a low-emission zone in the heart of the city. Building on this success, DPDgroup plans to extend the initiative to 20 focus cities across Europe by 2021. Hamburg is one of them. In our opinion this is a great example of how responsible local action can contribute to the well-being of cities and their residents.
