The Urban Transport Group in the United Kingdom has highlighted the urgent need for major cities to ramp up the adoption of zero-emission buses (ZEBs) to meet ambitious net zero targets. With a goal of converting around 15,000 buses to zero emissions by 2036, the report sheds light on the current low percentage of ZEBs in operation, particularly outside of London. Manufacturers stress the importance of having a clear end date for non-zero-emission bus sales to provide long-term confidence. The report also emphasizes the necessity of government funding for local authorities to achieve their net zero fleet decarbonisation goals. Additionally, recommendations include negotiating discounted bulk orders with manufacturers and upgrading bus depots to support ZEB infrastructure. The potential benefits of enhanced ZEB presence on the streets range from reduced emissions and cleaner air to economic growth and increased public transport usage, showcasing a positive outlook on the transition. While challenges exist, such as manufacturing and infrastructure deployment hurdles, the commitment of city regions to achieving net zero is evident.
