We want to make sustainability a component of all our business processes and of our employees' everyday lives. Our integrated health, safety and environmental (HSE) management system assists with this at the Group level. The management system helps us systematically to plan, implement and improve our HSE processes. This promotes the health of our employees and has a positive effect on their performance. It is also beneficial when it comes to bidding on new projects, since an increasing number of potential customers now require their suppliers to provide HSE certificates.
Our Group-level HSE management system is covered by an umbrella certificate based on the international standards OHSAS 18001 for occupational health and safety and ISO 14001 for environmental management. For some units, it also covers international standard ISO 9001 for quality management. Some of the national companies are not covered by an umbrella certificate because they have their own certifications which are, in part, even more comprehensive. This is the case in Greece, for example. This national company has an integrated management system, which in addition to the above-mentioned standards, also covers the international standards ISO 50001 for energy management and ISO 27001 for data security. Telekom Deutschland also has an environmental certification.
Through our compliance with legal regulations, we already meet the essential requirements for OHSAS 18001 certification in Germany. All employees in Germany and 99 percent of employees outside of Germany are employed at an OHSAS 18001-certified workplace. Some 93 percent of employees in Germany are employed at an ISO 14001-certified workplace. Internationally, we are at 83 percent coverage. Our goal is to cover all companies that have more than 50 employees by the end of 2018. Furthermore, we have additional certificates outside of Germany for our health, safety and environmental management systems, with which we cover 99 percent of our international employees.
