It could well be the best time to invest in an environmentally friendly vehicle as the humble motor is much greener today than ever before with new cars being 20% cleaner and those of pre 2000 and much more fuel-efficient that the older models.
The rule of thumb is that less carbon dioxide is produced on cars with smaller engines and more fuel efficient the car the lower overall emissions and of course the lower the emissions the lower the tax on the car with no road tax paid by cars that are the greenest by emit up to 100g of CO2 per kilometer with other cars that are not so emission friendly paying up to £950 the first year and up to £435 thereafter.
Road transport, per a 2008 report, produced over 25% of the total emissions in the UK of which 55% were cars and there are an estimated 29 million cars registered for the road says an Energy Saving Trust report.
While looking to buy a new car there are several things to be aware of; the most economical cars emit the least amount of carbon dioxide, so it is important to check fuel efficiency. For the more budget conscious buyer there are fuel efficient cars available like the Smart Fortwo that releases only 86g per km and costs only £9,800.
Another option for a greener car is the hybrid that switches between an electric and petrol engine it means your car runs quieter and you have less trips to the garage forecourt. The list of hybrids is growing with the Toyota and their Auris and Pruis and Honda with its Insight and Civic but the prices for these are much higher and approach £20,000 for a new one.
