London Mayor Sadiq Khan has unveiled a plan to transition London's iconic red double-decker buses to an emission-free fleet by 2030. This initiative aims to combat the city's air pollution crisis, with all 8,600 buses set to be replaced with either battery-powered or hydrogen-powered alternatives. The decision marks a significant step in enhancing environmental sustainability and reducing harmful emissions in the bustling city. The current diesel-powered buses, including the renowned NB4L or 'Boris Bus', will be phased out as part of this eco-friendly transformation. Although some Londoners and tourists cherish the nostalgia associated with the traditional buses, the shift towards cleaner public transport signifies a commitment to a greener future and improved air quality for all residents and visitors.
