Question 1

Which transportation mode produces the LOWEST carbon dioxide emissions per tonne-kilometer on average?

Accepted Answer

Ocean container shipping

Answer

Ocean container shipping produces roughly 10–15 grams of CO2 per tonne-kilometer, far less than trucking or air freight.

Question 2

What is 'carbon offsetting' in logistics operations?

Accepted Answer

Purchasing credits that fund emission reduction projects to compensate for unavoidable emissions

Answer

Carbon offsetting involves buying credits tied to projects that reduce or sequester emissions elsewhere, compensating for emissions that cannot yet be eliminated.

Question 3

A company adopts a 'circular economy' logistics model. Which practice is most consistent with this approach?

Accepted Answer

Designing packaging for reuse and establishing closed-loop return systems

Answer

Circular economy logistics emphasizes designing products and packaging for repeated use and building return systems to keep materials in circulation.

Question 4

Which key performance indicator (KPI) best measures fleet fuel efficiency improvement over time?

Accepted Answer

Miles per gallon (MPG) or liters per 100 km across the fleet

Answer

Fleet MPG or fuel consumption per distance is the direct measure of fuel efficiency and directly correlates with emissions and operating costs.

Question 5

What is the environmental advantage of cross-docking in a distribution network?

Accepted Answer

It reduces storage time and consolidates loads, cutting transport trips and energy use

Answer

Cross-docking minimizes storage energy consumption and enables load consolidation, reducing the number of vehicle trips and associated emissions.
