Classification Method of Energy Efficiency and CO2 Emission Intensity of Commercial Trucks in China's Road Transport

With the rapid economic growth in China, the road transportation system was becoming one of the largest and most rapidly growing oil consumers in China. This paper focused on the current status and development trend of energy efficiency and CO2 emission intensity of commercial trucks. According to the statistical data of commercial trucks from China's Ministry of Transport, there were 10% ∼ 30% differences about the energy efficiency and CO2 emission intensity among different brands of trucks under the same mass section in the industry standard (JT719-2008). There have appeared a group of vehicle with low emission and high energy efficiency. Energy efficiency standards and energy efficiency label system have been proven to promote energy-saving technology progress. In order to promote the development of energy efficiency and CO2 emission intensity of commercial trucks, the ‘Top Runner’ method was proposed to classify the energy efficiency and CO2 emission intensity of commercial trucks by coincidence rate, which would lead the road transportation enterprises to high energy efficiency trucks.
