Abstract: With the acceleration of urbanization and the improvement of motorization level, traffic energy saving and emission reduction has become the sustainable development problem of urban transportation. Report to the 19^th Party Congress clearly puts forward to build the traffic power. The arrival of the big data age brings unprecedented opportunity and challenge for the statistic monitoring of vehicle energy consumption and emission. By using Big Data technology, we can fully tap the data resource potential of transportation industry and vehicle energy emission in China, improve the scale, quality and application level of data synchronously, give full play to the strategic function of data resources, and effectively improve the government service and supervision ability. At the same time, many things challenge the statistic monitoring work, such as the increasingly complex mass of data, constantly updated technical means, emerging new industry and new models, as well as energy conservation and environmental protection concerns.

Key words: transportation, Traffic Power, Big Data, energy emission statistic monitoring
