Sir Sadiq Khan's efforts to enhance London's air quality and reduce carbon emissions have reached a milestone with over 2,000 zero-emission buses now operating in the city. The recent conversion of route 337 to electric buses marks a significant step towards the goal of transforming the entire fleet of 8,800 buses by 2030. The Mayor's ambition to achieve a net zero carbon city by 2030 faces challenges due to lack of government funding, potentially delaying the complete transition to 2034. London's investment in zero-emission buses has not only improved air quality but also generated approximately 3,000 jobs in various UK locations. TfL's commitment to sustainability is evident through initiatives like the trial of tram-like buses with innovative pantograph charging technology. With 107 fully zero-emission bus routes and 30 partially converted, London stands as a leader in green public transportation in Western Europe.
