The aim of the workshop is to examine various types of standards and labels and to build upon lessons learned from concrete examples to identify issues and challenges to be addressed, discuss their potential contribution to improve sustainability of food systems, and propose measures in order to improve their effectiveness. The workshop will try to answer five crucial questions that could facilitate the uptake and scaling-up of VSS: (1) how to make them work for farmers and small food producers; (2) how can VSS be used to enable green trade opportunities, particularly in agri-food products not currently using VSS; (3) how to make them work for consumers globally; (4) how to make it work for the private sector; and (5) what is the role for public actors.
