Buses in Kaohsiung and Chiayi, as well as garbage trucks in many other areas, now run on 2-5 % biodiesel blends, and gas stations around the island offer B1 biodiesel (a 1 % blend). By 2010, all the diesel for sale in Taiwan is expected to be B2 (2 %) biodiesel. Biodiesel is nontoxic, renewable, and relatively nonflammable.
如今高雄、嘉義街上的公車及許多縣市的垃圾車，已全面添加 2 % 到 5 % 生質柴油，各加油站也已打出「B1 生質柴油」的招牌，預計 2010 年全台灣的化石柴油中，都將添加 2 %（B2）的生質柴油。
