John Lewis has announced it will be switching its delivery truck fuel to cow manure by 2021.
In a bid to reduce its reliance on polluting diesel fuel and switch to a carbon-neutral option, hundreds of the department store’s delivery vehicles will run on cow manure in two year’s time.
The retailer will start using renewable biomethane made from manure in almost 300 John Lewis and Waitrose vans as it looks to swap fuel sources under its supplier, CNG Fuels.
They’re also set to supply a 200-strong fleet of trucks for Courier Hermes, as well as delivery vans for Asda and Argos.
John Lewis currently runs 80 vans on biomethane from food waste, but plans to expand its green fleet by up to 200 vans within the next 18 months before switching to manure.
CNG told the Guardian that using biomethane made from food scraps reduces the carbon emissions of delivery trucks by 85 per cent compared with those running on diesel.
“Renewable biomethane sourced from manure is currently the best low-carbon solution for HGVs, but we want to be ready to support our customers when other technologies are commercially viable for freight transport,” CNG chief executive Philip Fjeld said to the Guardian.
Last year John Lewis announced it planned to switch all its heavy delivery trucks to biomethane-powered versions by 2028.
If that aim is achieved the new fleet will save more than 49,000 tonnes of carbon emissions every year, or the equivalent carbon footprint of just over 6,000 UK households.
