Viessmann has set the pace in the heating sector for decades now, with energy-saving technologies, efficient heating systems, certifications and awards for its innovations.
Certification according to ISO 9001
Viessmann was first certified according to ISO 9001 in 1994. The certification is monitored annually.
In April / May 2018, the quality management system at Viessmann was reviewed by external auditors as part of a re-certification audit. The audit has been successfully completed. During the spring of 2018 the TÜV Rheinland confirmed once again that our quality management system meets the requirements of ISO 9001.
The certificate according to ISO 9001 is valid through May 30, 2021.
Certification to Eco Management and Audit Scheme (EMAS)
Thanks to its exemplary and innovative environmental management, Viessmann is recognised as an environmental pioneer. Not only is Viessmann certified in accordance with the environmental standard ISO 14001, but the company also participates in the EU's Eco Audit Scheme (EMAS) – one of the most stringent regulations regarding environmental protection. This order prescribes the determination of measurable environmental goals, which go beyond the current environmental legislation.
Viessmann is the third business in Europe and the second in Germany that meets the Eco Audit requirements. The audit must be repeated by an independent environmental assessor every three years, and a monitoring audit must be carried out on an annual basis. The EMAS order was issued in 1993 and, although numerous other companies have eventually satisfied the Eco Audit requirements, Viessmann still retains its leading position — it is the only company in its sector to have all sites in Germany certified.
Certification to ISO 14 001
Alongside the European Eco Audit, which lays down stringent requirements regarding environmental transparency, stands the international standard EN ISO 14 001 regarding the implementation of a general environmental management system.
This standard also aims to continually improve the environmental performance of businesses. Unlike the Eco Audit, this standard is implemented without an environmental statement validated by an external environmental assessor or publication.
Certification to ISO 50001
Viessmann was certified according to EU standard ISO 50001 for its energy management system at the Allendorf site and further locations.
Increasing energy efficiency plays a key role in achieving energy and climate policy goals. Efficiency can thus be thought of as our most important resource. Consequently, ISO 50001 will gradually establish itself as the standard for industrial companies in the coming years.
