This study aims to analyse the impact of two transport pricing policies using the PLANET model. The transport policies are (1) a harmonisation of excise duties on petrol and diesel and (2) road pricing for heavy goods vehicles in accordance with the EU proposal for the Eurovignette III directive. The effects studied concern the consequences for the transport activity for persons and goods, the environmental impact and the impact on social welfare. For both policy types, the impact on the public budget is neutralized through general taxation or labour taxation.
