 +===== Short description =====
 +
 +In sub-category //1.A.3.b vii - Road Transport: Automobile Road Abrasion// emissions from road abrasion in Road Transport are reported. Therefore, this sub-category is an important source for a) particle emissions and b) emissions of heavy metals, POPs etc. included in these particles.

 +===== Methodology =====
 +
 +==== Activity data ====
 +
 +Abrasive emissions from tyre and brake wear are estimated based on vehicle-type specific mileage data. For detailed mileage data, please see [[sector:energy:fuel_combustion:transport:road_transport:abrasive_emissions_from_road_vehicles:start | superordinate chapter ]] on abrasive emissions from road vehicles.

 +Emissions from road abrasion are directly linked to driven mileage. Thus, the overall trend of emissions from road abrasion is similar to the trend for total driven mileage.
 +
 +All reported emissons from tyre and brake wear are connected directly to the mileage driven by the road vehicles covered.

 +===== Recalculations =====
 +
 +**Activity data** (mileage) have been revised due to the regular revision of the TREMOD model. (see [[sector:energy:fuel_combustion:transport:road_transport:abrasive_emissions_from_road_vehicles:start | superordinate chapter ]] ). 
 +
 +However, the biggest changes occur in the tier1 **emission factors** that have been revised during a research study.
 +The variety of old and revised emission factors cannot be compared here in a comprehendible way.
 +
 +<WRAP center round info 60%>
 +For more information on recalculated emission estimates for Base Year and 2018, please see the pollutant-specific recalculation tables following chapter [[general:recalculations:start | 8.1 - Recalculations]].

 +
 +===== Planned improvements =====
 +
 +Besides a routine revision of the underlying model, no specific improvements are planned.
