 +The following chart illustrates the increase in annual mileage of electric road vehicles in 10<sup>6</sup> kilometers. Despite the exponential growth, only about 1 per cent of annual mileage was "electric" in 2021 (7,000,000,000 of 682,831,000,000 km).

-With both **activity data** and **emission factors** unrevised, emission estimates remain unaltered compared to last year's submission.+Compared to last year's submission, mileage data has been revised widely due to the availability of additional data sources. 
 +However, total mileage changed only marginally.
