As well as harnessing solar energy, we have looked at other ways to reduce our carbon footprint. To that end, hydrotreated vegetable oil (HVO) fuel has provided an ultra-low emission alternative to diesel for in-house logistics vehicles – an initiative that makes the factory the first luxury automotive plant to run all in-house operations on renewable fuels or green electricity. A 34,000 litre tank and pump are used to fuel the ten logistics HGVs that transfer parts between the factory and a storage depot ten miles away, as well as over 20 smaller on-site vehicles including fleet cars and Bentley’s iconic Heritage Collection. The fuel itself, known as Green D+, cuts tailpipe CO2 emissions by over 86%, while reducing nitrous oxide by up to 30% and particulates by up to 80%, in comparison to conventional fuel.
Another project, dubbed Power Down, demonstrates what can be achieved when everyone is prepared to make small changes to the way they work. Estimates suggest that switching off devices such as screens, fans, lights and chargers at the end of every day could save up to 700kw – roughly the same amount of energy it takes to power three average sized homes.
