Voluntary sustainability standards (VSS) have become a significant element of the governance of international trade and production. Even though VSS are not mandatory (required by law), in practice they are often necessary for producers to participate in global value chains. Finally, VSS are often considered costly for producers.

The analysis is empirical, and it is based on a data collection project called Standards Map (SM), launched in 2011 by the International Trade Centre (ITC). The analysis covers a population of up to 180 VSS. This large-n approach allows for a macro-perspective which complements the existing literature characterized by micro-level studies.
