Environmental Governance by Contract: The Growing Role of Supply Chain Contracting

Corporate net zero climate commitments and environmental, social, and governance (ESG) policies have the potential to bypass barriers to international, national, and subnational government action on climate change and other environmental issues. This Article presents the results of a new empirical study that demonstrates the remarkably widespread use of environmental supply chain contracting requirements. The study finds that roughly 80% of the ten largest firms in seven global sectors include environmental requirements in supply chain contracting, a substantial increase over the 50% reported by a comparable study fifteen years ago. The Article concludes that the prevalence of environmental supply chain requirements, the types of contract requirements, and the motivations of the contracting parties signal new ways to fill important gaps in public governance.
