In determining which approach or combination of approaches is most appropriate to a particular State or context, there are many resources that can be consulted. One of the best is Principles of Environmental Enforcement, which was prepared by the U.S. Environmental Protection Agency and has been a resource for enhancing environmental laws and institutions in many States. It is available in Chinese, English, French, Serbian, and Spanish at http://www.inece.org/enforcementprinciples.html
