Shenzhen is expected to become China's first city to realize that all the buses in the city are pure electric buses by September this year. The city plans to build about 60,000 charging piles by 2018, significantly reducing vehicle exhaust emissions. At the same time, Shenzhen is speeding up the construction of a huge metro network, which currently serve a record of more than 5 million person-times during the day. By 2030, Shenzhen will have 30 metro lines with the operation mileage reaching over 1,000 kilometers. Green commuting and energy saving are now two highlights of Shenzhen as well as its important missions.

Since August 2010 when Shenzhen became one of the first pilot cities of carbon trading in China, it has been making all possible efforts to promote green and low-carbon travel, including replacement of fossil fuel-powered buses with new energy vehicles, rapid expansion of the metro network and adoption of new energy technology for port lifting equipment, in order to reduce carbon dioxide emissions.
    It is reported that some bus companies in Shenzhen have already completed replacement with pure electric buses. Following the principle of "appropriately advanced implementation", the Shenzhen Bus Group is making great efforts to promote the construction of charging infrastructure, and 270 bus lines of its four subsidiaries are now served with pure electric buses. As of the end of April 2017, Shenzhen has accumulatively deployed 14,603 pure electric buses, accounting for 90% of all the buses in service, and is expected to have all lines exclusively served with electric buses by 2017.

If all fossil fuel-powered buses in Shenzhen are replaced with electric buses, the city is expected to see the reduction of carbon dioxide emissions by nearly 100,000 tons and other exhaust pollutants by about 6,000 tons a year, contributing to low-carbon development, environmental protection and savings in energy consumption. To meet the requirement for the deployment and operation of pure eclectic buses, measures include speeding up of construction of charging facilities at 13 bus terminals and building stereo garages for bus have been taken. Shenzhen will have about 60,000 charging piles and all the buses will be pure electric buses by 2018.

To promote green commuting, the Urban Planning, Land and Resources Commission of Shenzhen Municipality has issued the "Shenzhen Rail Transit Plan (2016-2030)," according to which Shenzhen will have 32 urban rail transit lines with a total length of 114 kilometers. At present, eight subway lines are in operation, with the highest passenger traffic volume exceeding 5 million person-times on the peak day in May, which means a dramatic reduction in carbon dioxide emissions.

Since port lifting equipment is a major energy consumer, the Yantian Port and the Shekou Port of Shenzhen have also been promoting green operations to facilitate energy-saving and emission reduction initiatives. It is expected that by the end of 2020, the comprehensive energy consumption per unit of container throughput at ports in Shenzhen will be decreased by 5 percent compared with 2015; the carbon emissions per unit of container throughput will be decreased by 4 percent compared with 2015; the emissions of sulfur oxides, nitrogen oxides, and particulate matters of vessels during berthing will be decreased by 75 percent, 20 percent and 40 percent respectively compared with 2015.
