Courier-Mail. The state Government of South Australia will begin running Adelaide’s metroplitan trains and diesel buses with a B5 biodiesel blend (5% biodiesel) starting next month.

Over time, this will be increased to B20 (20%).

Adelaide Metro runs a fleet of 810 buses, of which 535 are dieses and the rest natural gas.  A trial biodiesel bus service has been in operation along selected routes since mid-2002.   

“This clean fuel initiative is part of our State Government plan to reduce greenhouse gas emissions and fuel consumption by doing our bit for the environment,” [Premier Mike] Rann said. “Together with the extensive use of compressed natural gas in buses and the purchase of new Euro 4 standard emission buses, this will make our public transport system fleet the cleanest in Australia.”

Rann also called for a meeting of Australian governments on greenhouse emissions.
