title: HBEFA3-based
---

Since version 0.21.0, SUMO is able to simulate vehicular pollutant
emissions based on the database application HBEFA in version 3.1. Though
HBEFA contains information about other pollutants, we decided to
implement only the following, major ones:

- CO<sub>2</sub>
- CO
- HC
- NO<sub>x</sub>
- PM<sub>x</sub>
- fuel consumption

## Vehicle Emission Classes

The vehicle classes below map directly to vehicle classes supplied by
[HBEFA](http://www.hbefa.net/). This is a major difference to the
clustering done with [HBEFA
2.1](../../Models/Emissions/HBEFA-based.md). Note, that within HBEFA
these classes are aggregates of more specific vehicle classes. To use
the emission classes below prepend the class name with the HBEFA3
prefix, e.g. `emissionClass="HBEFA3/PC_G_EU4"`.

The following tables give the emissionClass strings to use in the
definition of vehicle types.

Not all combinations of emissionClass and pollutant give meaningful
results. The following combinations are known to be faulty as of SUMO
0.21.0: LDV + NOx, LDV_G_EU0 + NOx, LDV_G_East + NOx, LDV_G_East +
PMx, PC_G_EU0 + NOx
