Greener car choices

We each have our part to play in reducing the environmental impact of our motoring and we are working to increase the ‘greener’ choices available to you on the Motability Scheme.


Exhaust emissions

Every car gives off different levels of exhaust emissions. One of the most harmful emissions is carbon dioxide (CO2) and car manufacturers are continually working to reduce this.

All new cars are tested and given a CO2 emission level rating. In line with banding introduced by the government, these range from A (the lowest CO2 emissions) to G (the highest CO2 emissions.) Cars with a CO2 emission level of 100g/km are considered low emission models. There are several low emission models available through the Motability Scheme. Look for the green leaf symbol on our Car Search .

The majority of the low emission cars (bands A and B) are the models with smaller engines and/or body size, making them potentially unsuitable for those who require more space, for wheelchair storage or to carry multiple passengers, for example.

We recognises that one size does not fit all, and we therefore offer greener choices for all class of vehicle. With emission levels differing by up to 65g/km between various small family cars and 100g/km between MPVs, your choice of car model could make a significant difference in your environmental impact.

Diesel or petrol

You might also like to consider the type of fuel your car would use. Petrol and diesel engines have different effects on the environment.

If most of the driving you do is long distance or on motorways, think about a diesel engine for fuel efficiency and lower CO2 emissions. Some manufacturers will fit an optional extra DPF (diesel particulate filter) which reduces air pollution from diesel engines.

If most of your driving is in town where congestion is heavier, air quality is more important, a petrol engine may be best as they produce fewer air pollutants such as nitrous oxide and particulates.

Fuel efficiency (mpg)

The amount of fuel you use depends on how many miles per gallon (mpg) a car will do. Cars with a higher mpg cost less to run and produce lower CO2 emissions. By choosing a more fuel-efficient engine, you could save in fuel costs and reduce your engine CO2 emissions by up to 24 percent.

Green driving tips

Check your tyres
Under-inflated tyres mean your engine has to work harder and will produce more CO2 emissions.      

Clear the clutter
Remove unnecessary clutter from your boot and reduce your engine's workload.

Stick to the speed limit
High speeds produce more emissions. At 70mph you could be using up to 15 per cent more fuel than at 50mph.

Slow down as you approach traffic jams
Stop-start traffic jams use more fuel. Slow down early and take your foot off the accelerator.

Don’t over-rev
Changing up a gear early can reduce revs. For diesels, change up when the rev counter reaches 2000rpm. For petrol cars, change up at 2500rpm.

Switch off your engine
If you are likely to be at a standstill for more than three minutes switch off your engine.

Close windows
Keeping your windows closed at higher speeds will use less fuel.

Cut down on air-conditioning
Air-conditioning increases fuel consumption and produces more emissions.
