Hey Michael, I tried searching in HBEFA page for the exact fuels used (I guess there are no buses running in gasoline, or really few as you said) and so I thought that maybe, the considered fuel for the "Bus" category would be only natural gas, once diesel is covered in the other EURO categories for heavy duty vehicles, and gasoline has its own category "HDV_G". I based my assumption in this help file from their website:
http://www.hbefa.net/e/help/HBEFA32_help_en.pdf where In page 15, they say: - Fuel = Fuel consumption - HBEFA 3.1/3.2 consider primarily diesel and petrol vehicles, but provides also emission factors for - PC CNG Euro-2 to Euro-6, PC LPG Euro-2 to Euro-6 and PC E85 Euro-4 to Euro-6 - Urban buses: CNG Thus what do you think? Maybe it is only CNG for urban buses? Thank you again, Deborah.
