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. | In sub-category //1.A.3.b vii - Road Transport: Automobile Road Abrasion// emissions from road abrasion in Road Transport are reported.

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. | Emissions from road abrasion are directly linked to driven mileage.
