London Gatwick has cut carbon emissions from its diesel vehicles by 90% by swapping the fuel for Hydrotreated Vegetable Oil (HVO). The switch means London Gatwick will save more than 950 tonnes of carbon emissions per annum. HVO is a low-carbon biofuel made from plant waste, oils and fats making it a more sustainable and lower-carbon alternative to diesel. All 300 diesel vehicles, 85% of London Gatwick’s fleet, are now powered by HVO until they are retired from use. They will then be replaced by electric vehicles as part of the airport’s sustainability policy, Decade of Change.
