The Stakeholder Feedback Round (SFR) must happen prior to the completion of validation and should take place for a minimum duration of two months There is no rule in GS4GG that a project must be Listed before it starts the SFR.  However, we recommend – as a minimum – that the SFR start after receiving SustainCERT’s Preliminary Review response.  This will allow you to consider any comments SustainCERT raises in your Preliminary Review before it starts.
