-**Activity data** (mileage) have been revised due to the regular revision of the TREMOD model. (see  [[[1-a-3-b-vi-vii-emissions-from-wear-and-abrasion | superordinate chapter]]]). +With both **activity data** and **emission factors** unrevised, emission estimates remain unaltered compared to last year's submission.
  
-However, the biggest changes occur in the tier1 **emission factors** that have been revised fundamentally in order to be in line with the tier1 default values provided in the EMEP/EEA Guidebook 2019. 
-Unfortunately, the variety of old and revised emission factors cannot be compared here in a comprehendible way.
