The article discusses the significant progress made by European countries in adopting zero-emission city buses, particularly focusing on electric buses. Countries like the Netherlands, Finland, and Iceland have fully embraced battery-electric buses, setting a high standard for clean transportation. The European Union has seen a notable shift, with almost half of new city buses being zero-emission in 2024, driven by strict regulations and city-level initiatives. While some countries such as Spain, the UK, and Italy are leading in this transition, others like Austria and Czechia are slower to adopt, although Estonia made significant progress by introducing electric buses in Tallinn. The push for hydrogen buses is also gaining momentum, doubling its market share in 2024. The article highlights the importance of smarter government purchasing policies to promote the uptake of zero-emission buses manufactured in Europe. Hybrid and gas-powered buses are gradually decreasing in sales, reinforcing the shift towards electric fleets. Overall, there is optimism about the EU's direction, with predictions that more than half of new city buses will be zero-emission in 2025, potentially accelerating the transition to cleaner transportation.
