The key objective of this paper is to bring about the notion of "Marketable permits" into consideration in Indonesian academic and policy-level discourse on environmental issues. It shows how economics has cvolved in its mission to find a way around preserving the environment while ensuring economic activities. As an alternative to the more traditional yet widely adopted, "command-and-control" approach, economists have offered ti relatively new approach, namely "iradable marketable peemits". It is another from the "market approach, previously represented by the the "tax and/or subsidy" approach. This paper focuses on the marketable permits. In particular, it summarizes the recent development in the field with a hope to provide a fruitful alternative to help solve the problem in Indonesia. Nevertheless, some caveats are discussed.
