Potential effects are listed for those integrated energy-saving technologies for conventional vehicles. Low carbon transitions, including alternative vehicle power train systems and fuels, are discussed on their development status and trends, including life cycle primary fossil energy use and greenhouse gas emissions of each pathway. To further support the low-carbon vehicle technologies development, integrated policies should seek to： （1） employ those integrated energy-saving technologies, （2） apply hybrid electric technology, （3） commercialize electric vehicles through battery technology innovation, （4） support fuel cell vehicles and hydrogen technology R＆D for future potential applications, （5） boost the R＆D of second generation biofuel technology, and （6） conduct further research on applying low-carbon technologies including CO2 capture and storage technology to coal-based transportation solutions.展开更多
