European cities are moving towards a greener future with the mandate for city buses to achieve zero emissions by 2035. In 2024, nearly 50% of new buses sold in Europe were zero-emission, surpassing the CO2 standards set by the EU. This success is credited to European regulations that are phasing out diesel buses, emphasizing the adoption of electric and hydrogen buses. The NGO Transport and Environment highlights that if the current growth continues, all new urban buses purchased in 2027 will be zero-emission. Countries like the Netherlands, Iceland, and Finland are at the forefront of this transition, with high percentages of new electric buses. However, some countries like France and Germany are lagging behind, choosing gas-powered buses, which could delay their transition to cleaner technologies. The shift to electric and hydrogen buses is seen as a positive step towards reducing emissions and improving air quality in urban areas, with Spain and the UK also making significant progress in this area.
