1.3. Emission Factors for Vehicles

Try these first

1. 1.

   What is an emission factor?

   Hint

   Think about how emissions relate to fuel usage.

2. 2.

   Name one factor that can affect emission factors.

   Hint

   Consider different types of fuels like gasoline and diesel.

3. 3.

   What does an emission factor represent?

   • The cost of fuel
   • The amount of pollutants emitted per unit of activity
   • The distance traveled by a vehicle

   Hint

   Think about what measures pollutants.

4. 4.

   Organizations like ARAI measure emission factors under standardized conditions.

   • True
   • False

   Hint

   Recall what defines reliability in measurements.

5. 5.

   Suppose a diesel vehicle emits 50 g/km of CO2 and a gasoline vehicle emits 120 g/km. How does the difference affect air quality regulations?

   Hint

   Consider the significance of each pollutant in environmental discussions.

6. 6.

   Given that emission factors for older vehicles can be consistently higher, propose a strategy for policy changes to reduce pollution from this sector.

   Hint

   Think about financial incentives or regulatory requirements.
