Why has the ZNU Standard - driving sustainable change been revised?
The ZNU Standard – driving sustainable change was developed for and together with the food industry in 2013 and has been tried and tested in practice for six years. As a result, enterprises along the value chain as well as other industries took notice of the ZNU Standard – driving sustainable change so that manufacturers of other consumer goods (e.g., cosmetics and pet food or logistics and food services) could be certified according to the ZNU Standard – driving sustainable change. Another objective was to make the standard more accessible: Now it is also applicable to companies with several sites – and on an international scale as well. Last but not least, the quality of a standard is about reviewing it on a regular basis and adapting its contents to current issues as well as to modifications of other standards and initiatives. The present ZNU Standard – driving sustainable change may therefore serve the business community as an instrument for implementing global sustainability goals.

The certification body issues the ZNU Standard – driving sustainable change certificate for a period of three years. An annual review ensures that the company complies with and implements the requirements of the ZNU Standard – driving sustainable change. Before the certificate expires, it is possible to extend it for a further period of three years by passing a re-certification audit.
What changes result from the revision?
The ZNU StandardFood turns into the ZNU Standard – driving sustainable change: open to all industries, to manufacturers as well as to service providers, and applicable on an international scale. In addition, the site-specific standard turns into a corporate standard facilitating multi-site certification, thus simplifying the certification process for large companies with several sites or branches.
The standard is subdivided into nine documents for a better overview:
Z 1 (Objectives and overview) and Z 2 (Requirements including compliance options) are the standard’s core documents. Documents Z 3 to Z 9 include further information on the standard and certification system. That way, the information is provided in a more targeted and clearer way.
