Resumen: n recent decades, Spain has undergone a strong economic expansion; however, it has not made a robust response to fulfil the international greenhouse gas Paris Agreement targets. Thus, understanding the dynamics of the environmental performance of the Spanish regions is essential for policymakers. We explore the convergence process of emissions intensity at the regional level during 1990–2018, differentiating between direct and diffuse emission sector, based on the degree of energy intensity of economic activities, which is the most novel aspect of our analysis. Our results recognise several convergence clubs; predominantly, the determining factors are income level and added value breakdown, the energy mix of renewable power, as well as the temperature of the climate. In any event, the dispersion of behaviours and the existence of different factors driving the convergence process highlight the need for customised policies at the regional scale.
