Nearly half of motorists (48%) say they would not consider a more eco-friendly vehicle if Vehicle Excise Duty (VED) tax breaks were increased

Meanwhile, 50% think that it is fair that VED on cars is based on the CO2 it produces, 32% think parking permit prices should be based on the size or length of the vehicle - the more space it takes up, the more you pay - and 29% think that everyone should pay the same. Only 5% of respondents felt that the CO2 emissions the vehicle produces should influence permit costs.

Low Emission Zones (LEZs) are slightly more popular, according to a poll by the IAM (Institute of Advanced Motorists).

LEZs were introduced in London in 2008 to reduce pollution from heavy diesel vehicles and 46% of drivers think they that they should be introduced for private vehicles, 41% disagree.

Interestingly, more than one in every five motorists (22%) think that driving has no impact on global warming. This is in line with other surveys that show 7% of people think global warming is not happening and 17% believe it is panic about an exaggerated threat.

IAM chief executive Simon Best said: "Eco-friendly vehicles haven't got the appeal so much so motorists are willing to pay higher costs in VED to compromise. Motorists aren't fully convinced of how low CO2 emissions are beneficial to them, or society.

"While more can be done to increase awareness about the benefits of eco cars, drivers can do their bit by changing to green driving to help reduce CO2. Looking ahead and anticipating hazards will mean less stopping and starting and a smoother journey." (Source: Fleet News)
