Last updated on 16 Oct 2015 06:19 (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 2006.

In contrast, tier1 emission factors remain unchanged compared to submission 2014.

Due to the broad changes in the NFR structure, no sector- and pollutant-specific information on the impacts on emission estimates are provided in chapter 8.1 - Recalculations with this submission.

Planned improvements

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