Since January 1, 2008, all the vehicles in the STL’s fleet have been filling up with gasoline made of B5 biodiesel, which comes from recycling used cooking oil and animal fat.
Using this fuel helps cut down on CO2 emissions at a rate of 926 metric tons annually, which is equivalent to removing 200 vehicles from the road, each covering a distance of 20,000 kilometres per year. This is a significant contribution toward reducing greenhouse gases, and the STL will be pursuing its efforts in this regard.
