    Ojo, el estudio es engañoso. En el Scope ya advierte que sólo se están teniendo en cuenta las emisiones del tanque a la rueda, no del pozo a la rueda. Las emisiones del pozo a la rueda sólo se tienen en cuenta para la fabricación y reciclaje del vehículo, pero no durante su uso.

    “Green NCAP’s tests currently involve the measurement of gaseous emissions in a range of different test environments, both in the laboratory and on the road. The tests therefore consider only the emissions generated by the vehicle once it is on the road. This is known as ‘tank to wheel’ assessment. However, on a global scale, other factors are important too. For petrol and diesel engines, the energy expended in extracting the fuel and delivering it to the point of sale is important; for electric vehicles, the energy ‘mix’ of the electricity used for charging the car is important – good if comes from renewable energy; bad if it comes from fossil fuels like coal. This measure of emissions is known as ‘well to wheel’. Ultimately, all of the energy that goes into producing the car in the first place should also be considered – a whole ‘life-cycle’ assessment. This is Green NCAP’s ultimate aim: to be able to inform consumers which vehicles are the least damaging to produce, operate and, at the end of their useful lives, to destruct and recycle. However, at the start, Green NCAP will focus on ‘tank to wheel’ emissions.

    ‘Tank to wheel’: the tests consider only the emission generated by the vehicle once it is on the road.”
