City Vehicles in Beijing
Total Vehicles in Beijing： 5,168,000 (2012-09-31)
Cars： 4,447,000 (2012-09-31)
Trucks： 425,000 (2011-12-31)
Busses： 42,887 (2011-12-31)
Public Transit Busses ： 21,628 (2011-12-31) Taxies： 66,646 (201112-31) Sanitation Vehicles ： 7,400 City Trucks for Goods and Materials: 42,000
Why? …… City CO2 Reduction
In Beijing, each transit bus runs 200km per day averagely
with an average fuel consumption of 45liter/100km. If it is
replaced by an electric bus and runs 350 days per year,
there would save fuel by 31,500 liters and reduce CO2
emission by 63 tons after the consideration of 11 tons CO2
emission during the electricity generation process.

A fleet of 50 E-buses ran 24 hours a day, 7 days a week in the zero-emission central Olympic zone. The target of zero-failure operation is achieved.
EV for 2008 Beijing Olympics
EV for 2010 Shanghai Expo
1230 EVs including 120 E-buses operated in Shanghai Expo. Here the largest charging/Swap station in the world provided service for pure electric buses, amounting to 60,000 times of charging and battery exchange. An average of 500,000 passengers took the buses each day.

EV in 2010 Asian Games in Guangzhou
26 electric buses also operated successfully in the 2010 Asian Games in Guangzhou.
National Projects: 2011-2015
The “Ten Cities with 1000 EVs Each” Program has been launched by the national government. Actually 26 cities have received national support. Stimulus policies for private EVs are being tried out in 6 cities like Beijing, Shanghai, Hefei, Shenzhen, Hangzhou, Changchun.
