How other international cities achieve a long-term zero emission strategy for sustainable future development?



The mayor led the change. The London Mayor has stepped up to lead a move to tackle air pollution and public health threat by transforming its buses to zero emission.

  • London bus fleet (as of March 2020):
    3,773 hybrid buses / 316 electric buses / 10 hydrogen buses
    Total bus fleet: 9,102
  • 12 Low Emission Bus Zones have been implemented between 2017 and 2019 to tackle the worst air quality hotspot outside central London
  • Since 2020, all double-deck buses are hybrid and all single-deck buses are zero exhaust emission across Central London
  • By 2037 at the least, all 9,200 buses running in London will be zero emission
  • The entire public transport system in London will be zero emission by 2050. The radical plans focus on increasing walking, cycling and public transport use; transforming bus fleet and taxis to zero emission.



Tokyo announced its commitment to net zero emission by 2050.

The Japan Government set out a hydrogen dream to respond to the emerging threats on energy security and carbon emission restriction. Tokyo strives to demonstrate to the world the potential of a hydrogen economy for the 2020 Olympics.

  • Introduce 300+ zero emission buses by 2030
  • All cars drive in Tokyo to be zero emission vehicles by 2050
  • 1000 fast charges and 150 hydrogen stations will be set up before 2030



Singapore launched its Land Transport Master Plan 2040 (LTMP 2040) to envision how might a transport system should be designed to support a healthier and cleaner country. The Plan opens up doors for the transformation of the bus fleet to clean energy.

  • Introduce 50 diesel hybrid buses since 2018 for trial
  • 10 fully electric double-deck buses and 15 electric single-deck buses have been deployed on roads in 2020
  • The Government is committed to having a 100% cleaner energy public bus and taxi fleets by 2040
  • Aim to deploy 60,000 charging points at carparks and private premises for EVs by 2030



China set out a new energy vehicle program in 2009 to invest in vehicle and infrastructure in 10+ pilot cities. Shenzhen is the world’s first major city to run an entire electric bus and taxi fleets. Now, more than 16,000 electric buses and 22,000 electric taxis running across the taxi.

  • The electrification of the bus fleet was completed in 2017
  • All taxis in Shenzhen converted to electric-powered in 2018
  • The electric bus fleet reduces annual CO2 emission by 440,000 tonnes and emits fewer pollutants on roads
