Last updated on 29 Aug 2019 09:29 (cf. Authors)

Short description

In sub-categories 1.A.3.b vi & vii emissions from automobile tyre and brake wear & road abrasion are reported. Therefore, these sub-categories are important sources for a) particle emissions and b) emissions of heavy metals, POPs etc. included in these particles.

NFR-Code Name of Category
1.A.3.b vi Automobile Tyre and Brake Wear
1.A.3.b vii Automobile Road Abrasion

Activity data

Specific mileage data for all different types of road vehicles are generated within TREMOD [1].
The following table provides an overview of annual mileages.

Discussion of emission trends

Please see sub-category chapters 1.A.3.b vi - Tyre and Brake Wear and 1.A.3.b vii - Road Abrasion.

Recalculations

Recalculations were carried out due to a regular the revision of the TREMOD software, resulting in changes in mileage data for 2016 only.
Here, the main revisions took place for passenger cars, with all other data remaining unchanged.

For changes in the emission factors applied, please refer to the sub-ordinate chapters on tyre and brake wear and road abrasion.

Emission estimates

For specific information on recalculated emission estimates for Base Year and 2016, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations.

Planned improvements

Besides the routine revision of the TREMOD model, no specific improvements are planned.
