Lamborghini has clearly misunderstood the meaning of ‘Going Green’. Lamborghini’s interpretation of a green car (pictured above) is the 640 hp Murcielago LP640 in a Lime Green paint job, which does not go well with the Environmental Transport Association (ETA) of the UK.

While the world is increasingly becoming environment-conscious, there are a few car manufactures with their ‘heart over mind’ approach who seem to care little about the rants of environmentalists. Lamborghini Murcielago’s notoriety in this regard has encouraged ETA to award it the ‘Least Greenest Car of the Year’ title.

ETA has released the list of the ‘Greenest’ and the ‘Least Greenest’ cars in all categories and the Lamborghini has fared the worst. ETA examines over a 5,000 car models every year to pick the winners and losers of the ‘Green Car of the Year’ award in 11 categories.

With emissions five times worse than the greenest car, the Lamborghini is the bull in an environmental china shop. Thankfully, there are very few on the roads and there is an increasing choice of environmentally-sound cars.

ETA reports that the Lamborghini Murcielago produces as much CO2 as a ‘football field full of tress’. The winner of the ‘Green Car of the Year 2010′ award is the Toyota iQ. The ‘Least Green car’ is five times worse than the Toyota iQ in polluting the environment.
