The value of the sustainability of the development of the Ansaldo STS Group is twofold: one aspect is connected with the accomplishment of our mission, i.e. the development of railway and mass transit transport systems through the implementation of ever more advanced, safe and environmentally friendly products and solutions, in order to stimulate their use, the other is connected with the procedures through which the company accomplishes its mission: the strategies of Ansaldo STS concern the economic, social and environmental dimension of its development. Furthermore, the Management Systems adopted by Ansaldo STS, which are based on a combination of shared values, allow the Group to ensure consistency between the culture of a responsible conduct and the actions of the individual collaborators, thus enabling the company to continue in its path of sustainable growth.
