In 2021, 68.8% of buses registered in the European Union are diesel-powered.

Acea, the European Association of Automobile Manufacturers, took the picture of the market, which also recorded strong growth in electric-charging vehicles, with a consequent increase in their market share from 6.1% in 2020 to 10.6% last year. Alternative fuels power 10.5% of all new buses sold, while hybrid electric vehicles accounted for 10.1%. Together, all alternatively powered vehicles accounted for 31.2% of the EU bus market in 2021. Last year, the European Union's demand for diesel buses fell by 2.9% to 19,895 units, with a share reduced from 73.2% in 2020 to 68.8%, as mentioned. Of the four main EU countries-markets, only Italy recorded an increase in diesel sales (+ 7.9%); Spain recorded a double-digit decline (-19.8%), followed by Germany (-8.5%) and France (-2.4%).
