The UAH has prepared a series of activities for December coinciding with the celebration in Madrid of the COP25. The first one took place last Tuesday, day 3 in the context of the summit itself. The six Madrid public universities that make up the CRUMA have held sessions with the participation of their rectors and experts from each of these institutions. In the case of UAH, professors Emilio Chuvieco (director of the Chair of Environmental Ethics) and Mª Jesús Salado (director of Environmental Sustainability of the University of Alcalá) have intervened.
