3. 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

4. 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.

7. 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.

9. 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.
