This document provides an overview of market-based instruments (MBIs) for environmental regulation. It discusses the need for MBIs and examples like cap-and-trade programs and environmental offsets. Cap-and-trade programs set a limit on pollution and allow trading of permits between companies. Offsets allow pollution in one area if equivalent reductions are made elsewhere. The document also examines MBIs compared to traditional command-and-control regulation and examples of MBIs used in India, including a case study of the US Acid Rain Program sulfur dioxide cap-and-trade system.
