Research on "Green Management Matters" has tended to focus at the levels of organizational strategy and institutional change. Between these levels lies the supply chain or value chain, a critical focus for analysis and practice in moving toward more environmentally sustainable business practices. Governance of value chains, and innovation and change across firms in the chain, can multiply the positive impact of a firm seeking to improve its ecological footprint. Yet doing so requires strategizing and partnering across boundaries, seeing broader systems of which the firm is part, and institutionalizing change across multiple organizations, as Peter Senge and colleagues have recently demonstrated. This panel explores these challenges inherent in moving toward sustainable value chains, the capabilities required of firms and their partners, and open questions for research. The participants, heralding from academia and research-based NGOs, have played leadership roles in clarifying this territory and defining the art and science of sustainable value chains.
