The inventory of CO2 emissions from freight vehicles in Guiyang
was calculated. As shown in Table 3.1, the number of vehicles
(only referring to freight vehicles) in Guiyang was 60,200, and their
CO2 emissions totalled 440,600 tonnes in 2011.
Table 3.1 Guiyang’s Inventory of CO2 Emissions from Freight Vehicles in 2011 (10,000 t/a)
Vehicle types Fuel Types Number CO2
Light-duty freight vehicle Gasoline 22,982 20.81
Diesel 24,897 24.11
Heavy-duty freight vehicle Gasoline 316 0.87
Diesel 12,014 23.80
Total (ten thousands) 60,209 69.60
From Table 3.1, it can be observed that the light-duty diesel vehicle is
the largest source of CO2 emissions (241,100 tonnes/year), followed
by the heavy-duty diesel vehicles (238,000 tonnes/year), light-duty
gasoline vehicles (208,100 tonnes/year), and heavy-duty gasoline
vehicles (8,700 tonnes/year). The heavy-duty gasoline vehicles
produced less CO2 emissions because the number of this type of
vehicle is the smallest, while the light-duty diesel vehicles is the largest
in number. Its running emission factor is only second to the heavy-
duty diesel vehicles.

from Freight Vehicles in Guiyang
3.7.1 Quantitative Prediction of Freight Vehicles in
Guiyang in 2015
The study discussed in this chapter predicts the quantity of freight
vehicles in Guiyang in 2015 by applying the LEAP (long-range energy
alternative planning) model, and calculates the elastic coefficient by
applying the regression algorithm. The results of the forecast are
shown in Figure 3.7.
3.7.2 Scenario Design of Emission Reduction for
Motor Vehicles
In recent years, Guiyang has actively taken optimization measures
for freight transport so as to control the CO2 emission from freight
vehicles, such as implementing the stricter vehicle emission standards
of the state, eliminating aged motor vehicles, promoting clean fuel
