Creating climate-neutral electronic communications is a shared responsibility for the industry and urgent action is needed in the face of warming trends due to global climate change. Despite this, environmental sustainability in the regulation of the electronic communications sector in Hungary has not yet received sufficient attention, nor has there been any related research, articles or studies. Therefore, the aim of this paper is to fill this gap, to review the relevant international, EU and domestic regulatory situation and trends, to provide a comprehensive and high-level picture of sustainability initiatives in the electronic communications sector and to evaluate it in order to suggest possible directions for domestic regulatory action. It is hoped that this will serve as a starting point for launching a discourse in the industry and for properly positioning the green transition in electronic communications regulation.
