Edinburgh airport has started using a form of vegetable oil to fuel some of its ground vehicles to reduce its carbon emissions.
The Scottish airport has converted 34 of its airside vehicles from diesel to using hydrotreated vegetable oil (HVO), which is a renewable fuel capable of removing up to 90 per cent of CO2 emissions.
Gordon Robertson, the airport’s director of communications and sustainability, said using vegetable oil to fuel its airside vehicles was part of a strategy to "actively chip away at our emissions by replacing diesel with a renewable fuel source”.
Edinburgh airport plans for another 30 airfield vehicles to be switched to HVO in the next few months and it has also installed an on-site HVO fuel pump.
