The percentage of supplies from certified suppliers reported an increase with respect to 2016 at Group level for the ISO 9001, ISO 14001 and OHSAS 18001 certification; this result is the consequence of both direct action taken by the Group companies, which systematically include the possession of certification in the calls for tenders or in the supplier qualification stage as a requirement for participation and/or incentive for the tender, and of the greater sensitivity acquired by the companies in considering the certification as a component of greater competitiveness.
