1.A.3.b vi-vii - Road Transport: Automobile Tyre and Brake Wear and Road Abrasion

Last updated on 31 Mar 2020 06:33 (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 fundamental revision of the TREMOD software.
