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

Last updated on 30 Aug 2017 16:54 (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 amounts of fuels consumed by LDV in Germany.

Recalculations

Recalculations were carried out due to a regular the revision of the TREMOD software, resulting in slight changes in mileage data for all years as of 2012.

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

For information on the impacts on 1990 and 2014 emission estimates, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations.

Planned improvements

At the moment, besides the routine revision of the TREMOD model, no category specific improvements are planned.
