Low emission zones: Effects on alternative-fuel vehicle uptake and fleet CO2 emissions

This study analyses the actual effect of a representative low-emission zone (LEZ) in terms shifting vehicle registrations towards alternative fuel technologies and its effectiveness for reducing fleet CO2 emissions. Vehicle registration data is combined with real life consumption values on individual model level, impact LEZ then determined via an econometric approach. The increase vehicles (AFV) shares due to found be significant but fosters rather fossil powered AFV plug-in hybrid electric than zero emission vehicles. reflected average emissions newly registered vehicles, which do not decrease significantly. In consequence, while effective measure stimulating shift low support non-electric as jeopardizes decarbonizing fleet.
