Traditional home delivery involves couriers delivering individual parcels to individual households, whereas locker delivery enables couriers to deliver multiple parcels to a single location. This means couriers can spend less time travelling from home-to-home and make their journeys more efficient (e.g. one stop with 50 drops versus 50 different stops. Locker deliveries also don’t rely on people being in to receive their parcels. Parcels can be delivered first-time without any need for second and third delivery attempts, or trips to depots when parcels can’t be delivered. These changes alone could cut CO2 emissions by up to two-thirds.
Locker delivery has also been shown to reduce mileage on the road by up to 95% per parcel compared to home delivery, reducing its contribution to global warming by 3 times in urban areas. This increases to 13 times within extra urban areas.
Air quality is another area that lockers can help to improve. Nitrous oxide from road vehicles has been on the decline since 2010, but the proportion from vans has kept on increasing. If parcels are grouped into locker drops, we can help to clean up the air which costs the UK a projected £3.7bn annually in health impacts.
By placing lockers on the route to where people work, shop and play, InPost is encouraging customers to make more out of their existing journeys (trip chaining), rather than making separate trips. This in turn reduces their carbon footprint and lowers emissions and exposure to road related pollutants.
