JRC B2 Seminar: “Ensuring a just energy transition: a distributional analysis of diesel tax reform in Spain with stakeholder engagement” – Eva Alonso-Epelde and Manuel Tomás


In Spain, the increase of the tax on diesel has sparked passionate debates. Arguments against it stressed its potential adverse effects on the economy and society. In this paper, we shed light on the distributional impact of raising the excise tax on diesel to the same level as on gasoline for final consumers and various compensation schemes jointly designed with several stakeholders. Results confirm that raising the diesel tax without offsets would have slightly regressive effects, with rural and middle-income households being the most affected in relative terms. However, the effects become progressive when the co-designed offsetting schemes are implemented.
