Transport, social development as an important medium and tool, is an important source of greenhouse gases. Case of Shanghai, 2009, car ownership in Shanghai reached 1.46 million, motor vehicle emissions account for the whole society has a significant share of carbon emissions. Passenger transport industry in Shanghai Energy Consumption structure, accounting for 65% of the community bus, taxi, 17%, 10% bus, rail, 7%, 1% ferry, individual mobility, urban transport sector as the main energy consumption, is the largest carbon source. In the current rapid growth of motorization in China under the premise of low-carbon transport is to achieve energy conservation, the development of an important part of a low carbon economy. 25 November 2009, the Chinese Government officially announced that the unit of GDP by 2020 carbon dioxide emissions in China from 2005 down from 40 to 45 percent, and as binding targets into national economic and social development and long-term planning, stress speed up the building to characterized by a low-carbon industry, construction and transportation system. Therefore, low-carbon transport system to speed up development is an important and urgent strategic task of changing the inherent requirement of transport development. Understand the "low-carbon transport" Low carbon transport is a kind of energy-efficient, low power consumption, low pollution and low emissions characteristics of the transport mode of development, its core is to improve the energy efficiency of transportation, improve transportation energy structure, optimization of traffic transport mode of development. Objective is to make transportation infrastructure and public transport system will eventually reduce the need for traditional fossil energy sources, represented by the high carbon intensity of energy consumption. To achieve low carbon transport, it is necessary to low-carbon technology. Transportation development is a continuous effort to "carbon reduction" process. As the means of transport must rely on energy consumption, unless the use of clean energy (such as solar, etc.), otherwise difficult to achieve carbon-free transport, can only continue the development of low carbon technology. Second is the importance reduction, especially transport emissions. "Energy" and "emissions" are low-carbon transport important way, it is necessary to attach importance to "saving", but must "reduce emissions" up to a certain height. Third is systematic. Is a low-carbon transport system with the concept, whether it is transportation system planning, construction, maintenance, operation, transportation, or transportation of production, use, maintenance, as well as related systems and technical security measures, people's travel mode or Transport consumption patterns and so on, need to "low carbon" of the idea to transform and optimization. 4 is integrated. On the one hand, the means of low-carbon technology is diverse, including both technical and carbon reduction (such as saving and environmental protection technology), including structured carbon reduction (such as by optimizing the network structure, capacity structure to improve energy efficiency), but also the system of carbon reduction (such as market access and exit mechanisms). On the other hand, carbon-based approach is a two-way, both the "supply" or "production" of carbon reduction (such as providing a more low-carbon transport services system), but also "demand" or "consumer" level carbon reduction (such as the rational choice of travel mode to guide the public to encourage use of public transport or by bicycle, etc.). Fifth, systemic. Complete low-carbon transport system should include three basic system. First, support system based on energy saving, low-carbon system is the first step in promoting the need to increase efforts to systematically improve the traditional work; Second, optimize the use of clean energy systems, developing new energy vehicles is low traffic important way carbonation; third public transportation system of social guidance, we should use all legal, economic, technological and even morality strength, correct guidance of public transport spending.
