The ETN is an international clearinghouse for information on current, past, and developing water quality trading projects and other environmental markets in the United States and globally.

Goals & Vision:

The ETN seeks to obtain, generate, and disseminate accurate and timely information on water quality trading and other market-based ecological programs, increasing public awareness and support. In this way, ETN envisions further facilitation and implementation of programs established through state and federal environmental regulations.


The ETN originated as the Great Lakes Trading Network in 1996 to support a Water Quality Trading Demonstration Project in the Kalamazoo River Basin of Michigan. With funding from the Great Lakes Protection Fund, it sought to share new information on trading within the broader Great Lakes Basin. Immediately, as national interest in the subject grew, several other active trading pilot projects in the U.S. desired to be a part of this information exchange. To accommodate this growing interest, the ETN took on its present name and form in 1998.

Since its foundation, the ETN has led and participated in a variety of market-based environmental market projects. In the Great Lakes, these projects focused on issues of water quality and water quantity and how markets or market-like mechanisms could be used to help maintain the balance between use and protection of water resources. The network maintains a principal focus on water quality trading, though it has expanded to include information regarding other relevant environmental markets including wetland and habitat banking.


The ETN is maintained through project funding and in-kind support from Kieser & Associates, LLC (K&A). Mark Kieser of K&A has voluntarily served as Acting Chair of the Network since 2000.  Contact us for more information:
