An integral evaluation of dieselisation policies for households' cars

► Unlike other approaches, I use an integral one to analyse diesel vehicle penetration. ► It is needed to make diesel cars lighter and accessible to all kind of drivers. ► Having more diesel vehicles will not reduce the amount of energy and CO2 emissions. ► It provides empirical evidence of the effect of improving vehicle efficiency. ► Taxing petrol cars and improving public transportation is the more efficient policy.
