New research from WMG has found that the carbon footprint of collecting and refurbishing abandoned trolleys adds up to the equivalent of flying from London to New York and back twice!

“Thousands of shopping trolleys are reported as abandoned in the UK every year. When you multiply the carbon impact of retrieving each one, it becomes both significant and concerning,” explains Neill Raath, Assistant Professor at WMG, University of Warwick, who led the research.

Despite supermarkets introducing a range of methods to stop shopping trolleys leaving their premises, including coin slots and wheel-locking mechanisms, over 520,000 are still reported as abandoned in the UKLink opens in a new window each year, according to global trolley and retail equipment manufacturer, Wanzl.

Supermarkets rely on commercial collection services, typically using diesel vans to survey suburban areas, to collect and return the trolleys. Researchers at WMG assessed the environmental impact in order to tally the true cost of abandoning a trolley.
