+ | ===== Short description===== | ||
+ | |||
+ | In sub-categories //1.A.3.b vi - Road transport: Automobile tyre and brake wear// emissions from automobile tyre and brake wear in RT are reported. Therefore, these sub-category is an important source for a) particle emissions and b) emissions of heavy metals, POPs etc. included in these particles. | ||

+ | |||
+ | ==== 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: | ||

+ | ===== Recalculations ===== | ||
+ | |||
+ | **Activity data** (mileage) have been revised due to the regular revision of the TREMOD model. (see [[sector: | ||
+ | |||
+ | 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. | ||

+ | For more information on recalculated emission estimates for Base Year and 2018, please see the pollutant-specific recalculation tables following chapter [[general: | ||

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