When Virgin Records singer/songwriter KT Tunstall criss-crosses the U.S. on a month-long headline tour starting this week (8th September), it will be in a bus that runs on biodiesel. 

Tunstall, whose Eye to the telescope album is certified gold in the US and triple-platinum in her native U.K., says that making the effort to use a bus modified for biodiesel was a gesture of respect to the environment, the country, and her American fans. "It seems unacceptable to tour using non-environmentally friendly fuel when there's an alternative available," Tunstall comments. "I'm very excited about venturing into a greener touring lifestyle, and I hope sooner rather than later, it becomes the norm for all little traveling circuses like us." She is traveling in a bus outfitted for B20 biofuel -- a 20% blend -- because a B100 bus (running on a pure biodiesel formula) could not be located on short notice, but she plans on using one on the next tour. Biodiesel is a renewable fuel made from vegetable oils or animal fats. It replaces fossil fuel in diesel engines, and results in reduced toxic gas and particulate emissions from vehicles that use it.
