IWA 26 is an ISO-deliverable that aims at helping users of ISO 26000 and users of ISO-management system standards understand each other a bit better. During the final plenary of the workshop a draft communication plan was initiated and it has now been finalized. It gives a good summary of the document and of why a management system approach to ISO 26000 can be beneficial. It is available here.
Let us know if you have examples of application of IWA 26 or management systems for social responsibility/sustainability.
