Handbook emission factors for road transport (HBEFA)


The Handbook Emission Factors for Road Transport (HBEFA) provides emission factors for all current vehicle categories (PC, LDV, HGV, urban buses, coaches and motor cycles), each divided into different categories, for a wide variety of traffic situations. Emission factors for all regulated and the most important non-regulated pollutants as well as fuel/energy consumption and CO2 are included.




In the HBEFA update of 3.11.2019, the shares of bioethanol in petrol in the Austrian fuel mix were unfortunately incorrect. This affects results for the pollutant "CO2(rep)" for petrol vehicles for the years 2007-2050 in Austria. A patch program to correct these values is available - please log in to download it.




An update of HBEFA 4.1 is now available. This affects mostly results for Austria and Norway. More information can be found here.




Version HBEFA 4.1 (August 2018) is now available and can be ordered online.
