The objective of this paper is to highlight some of the most important implementation issues associated with the greening of global value chains (GVCs). Special attention is given to how public policies and business strategies can support each other in meeting the challenge, particularly in developing countries. The first part calls for holding a systemic view of GVCs. The second part focuses on the incentives that should be set within member firms and throughout the supply chain. The third part considers the global coordination of business and public policies, and concludes that the greening of a GVC will certainly work best if its members and stakeholders move in tandem.
