Par: Shaun McCarthy. I will be spending the next four days negotiating the content of an ISO standard for sustainable purchasing with representatives from 16 nations. I have tried to set out the key principles we will be negotiating: • Using procurement to deliver sustainable outcomes • Focus on impacts material to the procurer • ‘Sustainable supply’ not ‘sustainable supplier’ • Not one-size-fits-all • Manage demand • Embedding sustainability into current procurement practice
