A business group has said learner drivers should be tested on their green knowledge.
The CBI claimed that a section on energy efficiency should be included in the test in a bid to cut emissions and help save drivers money.
It said the move would lead to smoother and more efficient drivers, while also cutting carbon emissions and bringing fuel savings of up to £250 per year.
Dr Neil Bentley, the CBI's director of business environment, said: "More than a quarter of the UK's greenhouse gases come from personal transport, half of which are from cars. Making small changes to the way we all drive will reduce carbon emissions and could save motorists up to £250 a year.
"Simply changing gears more smoothly to avoid sharp breaking and acceleration can reduce fuel consumption by a third. Learner drivers already have to demonstrate they can drive in a fuel-efficient way during the course of their driving test, but this is not a pass or fail element.
"Making energy-efficient driving techniques a mandatory part of the test will make a significant contribution to changing the next generation of motorists' behaviour, and to cutting transport emissions."
