RITZENHOFF has introduced an energy management system in accordance with DIN EN ISO 50001: 2011. The efficient use of energy is an integral part of the company policy. When procuring products, services and facilities that have or may have an impact on the significant use of energy, procurement is partly based in part on energy-related performance throughout the lifecycle. Our employees are convinced and committed to implement energy saving and energy efficiency measures successfully. Two years in a row now, we were able to successfully certify the ISO 50001: 2011 assessment on the basis of ISO 50003: 2014.
