Going green seems to be at the forefront of every lifestyle choice now; from recycling waste, to energy saving light bulbs, through to the car you drive. But following panic over global warning, the introduction of the Low Emission Zone in London, and the recent announcement by Chancellor Alistair Darling that cars with higher emissions will face higher road tax, choosing a green car has never been so important to road users in the UK.

The term 'Carbon Footprint' has rapidly become part of our vocabulary over the past couple of years through frequent use by everyone from environmental campaigners to MPs; and while we all understand that everything has one and the smaller it is the better, working out what your actual effect on the environment is and finding realistic options to decrease it can often be a source of confusion. That’s why Parker's has introduced its 'Carbon Footprint Calculator'. By taking just a few seconds to enter the make and model of your vehicle, plus the miles you travel every day, Parker's calculates the carbon footprint of your car, giving you the units of CO2 that you are producing per year.

While those who are passionate about pollution may be pleased to discover they are already driving a low emission motor, for everyone else the revolutionary tool not only provides you with the carbon facts about your current car, but also suggests greener alternatives along with reviews, ratings, depreciation values and all the buying and selling information you need should you be looking to switch to a more eco-friendly model.
