+ | ===== 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: | ||
+ | |||
+ | ==== Emission factors ==== | ||

+ | |||
+ | |||
+ | 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 ===== | ||
+ | |||
+ | With both **activity data** and **emission factors** unrevised, emission estimates remain unaltered compared to last year's submission. | ||
+ | |||
+ | <WRAP center round info 60%> | ||
+ | For more **information on recalculated emission estimates for Base Year and 2019**, 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. | ||
