I’m attaching a recording of the excellent webinar give by Jane Wright of Transport for London hosted by the London Hammersmith Network on 21st October 2021. In it Jane describes TfL's journey towards a zero-emission fleet by the early 2030's. The journey includes a retro-fit programme to a better-than Emission 6 standard fleet, trials on hydrogen fuel cell buses, the introduction of efficient hybrid buses and ultimately an all electric bus fleet. She also explains the operating and infrastructure constraints and TfL's solutions to dealing with these.
