This white paper examines the technology roadmap and costs for fuel efficiency increases and CO2 reduction in Chinese new passenger cars in 2030. The study was supported by the Energy Foundation China and the Aspen Global Change Institute, and the authors thank Dan Meszler, Hui He, Anup Bandivadekar, Nic Lutsey, and others for their technical support and critical comments. The study was conducted using a bottom-up approach, which involved analyzing the technical feasibility and cost of various technologies for improving fuel efficiency and reducing CO2 emissions in Chinese new passenger cars. The authors also considered the regulatory environment and market dynamics in China. The study found that a combination of technology and policy measures could achieve a 50% reduction in CO2 emissions from Chinese new passenger cars in 2030, at a cost of around $100 billion. The authors conclude that China has the potential to lead the global transition to cleaner and more efficient vehicles, and that government policies and investments will play a critical role in achieving this goal.
