How does ISO 20121 compare with the GRI guidelines?

Written by 

ISO 20121 is a management system, which provides a framework for your way of working to support the implementation of sustainability. A management system provides you with a framework for ‘how’ you should work. The ASTM standard provides a more prescriptive outline and could be described as a checklist approach where you are given details on ‘what’ you should do.

It is worth remembering that ISO 20121 is relevant for all types, locations and sizes of events and the ASTM standard has been created for meetings. These standards are not mutually exclusive and you could use ISO 20121 as your way of working and the ASTM standard as the specific actions that you implement.
