This paper from the International Council on Clean Transportation (ICCT) provides an in-depth look at the progression of China’s fuel consumption standards for heavy-duty vehicles, focusing on the first two regulatory stages between 2012 and 2017. Using certification data from over 10 million trucks and buses, the study analyses how these policies have shaped vehicle design, technology adoption, and certification practices across key commercial segments. It also examines the structure and effectiveness of China’s regulatory approach, laying the groundwork for future standards. This research offers valuable insight for policymakers, manufacturers, and researchers interested in the intersection of fuel efficiency, regulation, and vehicle technology in one of the world’s largest commercial vehicle markets.
