With up to half of clothing bought online returned to some retailers, the whole process is estimated to cost businesses about £7bn a year, according to a 2020 study by consultancy KPMG. It is tricky to measure
the environmental costs, but the transport, storage and disposal of items that cannot be resold because they are damaged or dirty is likely to weigh heavily on brands’ carbon footprints, and poses troubling questions about the dark side of the online sales boom.
Anita Balchandani at consultancy McKinsey says managing the flow of returned goods is a “sustainability imperative for the industry”, not just looking at the impact of the “last mile” delivery to, and from, homes – but also what happens to an item that is no longer wanted.
