On Monday 6th November we started the training course on “Sustainability, Energy Efficiency and Urban Mobility” given by NAIDER in the training centre of La Salle Irun, which is organised by Lanbide (Basque Employment Service), Bidasoa Activa – Bidasoa Bizirik and the centre itself. The first week of the course dealt with the different concepts related to sustainability, before starting the second week with energy issues, and finishing the last block related to sustainable mobility.
