Last updated on 01 Mar 2018 14:15 (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.

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 only marginal changes in mileage data for all years as of 2012.
Here, the main revisions took place for heavy-duty trucks, with all other data remaining more or less unchanged.

Emission estimates

For specific information on recalculated emssion estimates reported for Base Year and 2015, 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.
