To restrain the phenomenal increase in oil consumption in China, the Chinese government called for measures to reduce oil consumption of the road transportation sector through adopting vehicle fuel consumption standards. This paper describes the development of China's first set of fuel consumption standards for light-duty passenger vehicles. The adopted standards cover M1 class vehicles, which, according to European definition (and adopted by China), include passenger cars, minivans, and sports utility vehicles (SUVs). In particular, we present the goal, technical background, structure, and values of the adopted standards. We also present their potential effect on oil use reduction. The standards are set in liters of fuel consumption per 100 km for individual vehicle weight categories. The standards are maximum fuel consumption values for given vehicle weight categories.

Because of its abundance and because it offers significant energy and environmental advantages, natural gas has been promoted for use in motor vehicles. A number of transportation fuels are produced from natural gas; each is distinct in terms of upstream production activities and vehicle usage. In this paper, we present greenhouse gas emission impacts of using various natural gas–based transportation fuels. We include eight fuels – compressed natural gas, liquefied natural gas, liquefied petroleum gas, methanol, hydrogen, dimethyl ether, Fischer–Tropsch diesel, and electricity – for use in five types of motor vehicles – spark–ignition vehicles, compression–ignition vehicles, hybrid electric vehicles, battery–powered electric vehicles, and fuel–cell vehicles. In our evaluation, we separate these fuels and vehicle technologies into near– and long–term options to address technology progress over time.
