Virgin's biofuel flight is all spin and greenwash

With all the excitement happening today at Terminal One, it's worth remembering that yesterday was another eventful one in Heathrow's calendar as a Virgin Atlantic plane steered away from its usual transatlantic route to fly between Heathrow and Amsterdam. No, the guidance systems weren't malfunctioning: it was a test flight to demonstrate that biofuels can be used in aircraft. But what's that dripping from the undercarriage? Could it be a tonne of greenwash?

Virgin announced its plans to test biofuels some time ago but has been reluctant to say exactly what kind of biofuel they would be using. To quell concerns about the impact on the cost of food, a press release assured us that it wouldn't "compete with food and fresh water resources". The rumour was that it would be made from algae, but in the end it turned out to be a mixture of coconut and babassu oil. These aren't food crops as such, but if the aviation industry leaps on them as an apparently easy way to reduce emissions, that's going to have a huge environmental impact.
