16:00 – 17:30 - Auditorium 1


PRC’s automobile market has experienced 30 years of high-speed expansion, epitomizing the PRC’s economic miracle. Rapid motorization has brought a variety of benefits in industry development, societal advancement, travel convenience, as well as big challenges in air quality, energy security, climate change and human health. 

Over the last 20 years, PRC has phased in a succession of mobile source emissions control measures and developed a “Vehicle-Fuel-Road” integrated framework. For the time being, China VI standards for new vehicles and fuel quality have been fully implemented, a real-world emission regulation system incorporating multiple advanced techniques has been initially established, transportation structure & transport energy structure adjustment has been commenced and PRC has become the largest market for the promotion of electric vehicles. Because of these efforts, PRC has made impressive strides in reducing emissions from mobile sources. Megacities in PRC, in particular, have served as a pioneer in promoting these efforts. 

We believe that PRC's and particularly the megacities’ experiences with mobile source emission control can be helpful for other Asian countries that have pressing needs and ambitions to develop green transportation for clean air and decarbonization. This session will present the retrospectives on PRC’s transportation emission control and city experiences, as well as discussions about leapfrogging and opportunities for reducing mobile source emissions in Asian countries.


The session aims to introduce PRC’s progress and experiences over the course of its 20-year journey toward controlling mobile source emissions and key drivers for emission reduction, as well as joint discussions on opportunities for Asian countries towards green transportation. The session will discuss the following: 

  • PRC’s 20-year efforts in vehicle emission control 
  • City experience from Beijing, Chengdu, Shenzhen and Shanghai 
  • Leapfrogging and opportunities for Asian Countries
