Abstract: We project the well-to-wheels (WTW) and tank-to-wheels (TTW) fossil-energy use, petroleum use, and greenhouse gas (GHG) emissions of the road-transport sector in China up to year 2050 and evaluate the effects of various potential policy options with the fuel economy and environmental impacts (FEEI) model (http://www.feeimodel.org/). The policies evaluated include (1) vehicle fuel-consumption improvements, (2) dieselization, (3) vehicle electrification, and (4) fuel diversification, with plausible policy scenarios. Under the business-as-usual scenario, road transport in China would create 410–520 million metric tons (MMT) of oil-equivalent of TTW oil demand (three to four times the current level), 28–36 billion GJ of WTW energy demand, and 1900–2300MMT of CO2-equivalent of WTW GHG emissions by 2050. The policies (in the same order as above) are projected to reduce the TTW oil demand by 35%, 10%, 29%, and 44%, and reduce WTW GHG emissions by 34%, 5%, 12%, and 13%, respectively, by 2050. This evaluation reveals that the fuel-consumption improvement policy could achieve greater benefit in reducing oil use, fossil-energy use, and GHG emissions. Implications of each policy option are discussed and the uncertainties associated with the policy scenarios are analyzed.
