Europe is seeking ways to decrease the growing negative impact of passenger cars on climate, currently responsible for up to 12% of total EU CO₂ emissions. After biofuels in the nineties and hydrogen in 2000, the new answer to climate change appears to be electric. But contrary to many marketing messages, electric cars are not zero emissions cars. They will not necessarily contribute to actual CO₂ emission reductions before 2020 and even then, not in every country. 

Marie C. DONNELLY, DG Energy, reported that the EU is “unlikely to achieve a 20% reduction on the current set of policies” [1] by 2020. According to her, based on a modelling exercise, the estimate of energy savings “would be somewhere between 9 and 11% on current policies” in spite of the contribution of the economic crisis to decreasing the EU primary energy consumption.
