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 (see Methodology).
HBEFA is a standard data source for emission calculations in numerous studies and other applications (see Use cases). It is the product of a common effort by funding agencies and development partners in six countries (see Contact).
