Spanish supermarket chain Mercadona and its transport suppliers have allocated 4 million euros ($5m) in 2018 towards adding 40 liquefied natural gas (LNG)-powered trucks.
The trucks will be deployed in Madrid, Barcelona and Valencia.
They will join the 7 gas-powered vehicles that have already been operating since 2017 as part of the company’s plans to reduce carbon emissions, Mercadona said in a statement on Thursday.
The new LNG-powered trucks will gradually be incorporated into the company’s fleet throughout the year, it said.
