From decarbonization to depopulation: an emerging challenge for the carbon-intensive regions under the energy transition in Spain

Abstract

Since 1990, Spain has undergone a rapid decarbonization process focused on closing carbonintensive facilities such as coal mines and coal-fired power plants and promoting renewable energy sources. These facilities have been the main source of income and employment in the regions where they were located, in addition to being a major source of carbon emissions. Their closure can have a huge impact on the socioeconomic and demographic composition of these carbon-intensive regions, damaging the social fabric and accelerating the process of depopulation. Based on a detailed analysis of policy documents and demographic data (from municipal registers and the 1991-2011 census), this article aims to: first identify and delineate the main carbon-intensive regions in Spain that are vulnerable to the negative impacts of the ongoing decarbonization process; second, examine the different policy responses and phases of the decarbonization process in Spain; and finally, examine the impact of the decarbonization process on the demographic (size, structure, and composition of the population) and socioeconomic configuration of the different carbon-intensive regions in Spain.
