This quiz aims to

develop your analytical thinking and data-driven analysis skills in the context

of transport and environmental systems. You will work with real-world data from

the heavy vehicle sector in Australia to estimate total CO₂ emissions. Please download the Excel File of Quiz 4-Week 10 on Moodle.

You are provided with

several datasets related to

• Table 1

  :

  Number of vehicles and average vehicle kilometres travelled (VKT) for LCVs

• Table 2

  :

  Share of petrol vs diesel engines in the LCV fleet

• Table 3

  :

  Distribution of LCVs by age and corresponding Euro emission standards

• Table 4

  :

  CO₂

  emission factors (g/km) by vehicle type and Euro standard

• Table 5

  :

  Total annual fuel consumption (megalitres) for petrol and diesel LCVs

Q1. Using Tables 1–4, estimate the total NOx pollutants (in tonnes

), and

incorporate:

• The distribution of engine

  types (Table 2)

• The Euro standard mix (Table 3)
• Emission factors (Table 4)
