CPFM Environmental Sustainability & Green Fleet Management 2

Question 1

What is the main sustainability advantage of hybrid electric vehicles (HEVs) in fleet operations?

Accepted Answer

They improve fuel economy by recovering energy during braking through regenerative systems

Answer

HEVs use regenerative braking to capture kinetic energy that would otherwise be lost as heat and convert it to electricity, improving overall fuel economy and reducing emissions.

Question 2

Which greenhouse gas is most significantly associated with vehicle exhaust emissions and climate change?

Accepted Answer

Carbon dioxide (CO2)

Answer

Carbon dioxide (CO2) is the primary greenhouse gas emitted from vehicle exhaust as a direct byproduct of burning fossil fuels, making it the leading contributor to vehicle-related climate change.

Question 3

What does the acronym CAFE stand for in the context of U.S. vehicle fuel efficiency standards?

Accepted Answer

Corporate Average Fuel Economy

Answer

CAFE (Corporate Average Fuel Economy) standards set the average fuel efficiency that a manufacturer's entire vehicle fleet must achieve, driving improvements across the industry.

Question 4

Which telematics capability most directly helps a fleet manager reduce carbon emissions?

Accepted Answer

Driver behavior monitoring that identifies excessive idling and aggressive acceleration

Answer

Monitoring driver behaviors such as excessive idling, hard acceleration, and speeding directly reduces fuel consumption and greenhouse gas emissions fleet-wide.

Question 5

What is a key environmental benefit of converting a fleet from diesel to compressed natural gas (CNG)?

Accepted Answer

CNG combustion produces lower particulate matter and CO2 emissions compared to diesel

Answer

CNG combustion produces significantly lower particulate matter, nitrogen oxides, and CO2 emissions compared to diesel, making it an environmentally cleaner fuel for heavy-duty applications.
