In these hot days of the end of July a new station has been added to the SUDOE Stop CO2 Project. Now the sustainable stations network counts on thirteen infrastructures. Palencia Bus Station (the first of the Autonomous Community of Castilla y León in the project) has achieved three stars during the evaluation through the digital tool which evaluates the energy efficiency of the stations of transport. The managers of the station explained how, despite the economic difficulties, they are constantly modifying the building's lighting and heating systems in order to improve the energy efficiency and, above all, to reduce management costs.
