The Environmental Trading Network began in 1998 to support the Kalamazoo River (MI) Water Quality Trading Demonstration Project. In the past 5 years the Network has grown to include international representation.

The ETN is an organization dedicated solely to the development and implementation of successful water quality trading programs and other market-based strategies for achieving healthy sustainable ecosystems. It is the only national clearinghouse for key policy and regulatory issues, and transferable water quality trading program design elements.

The goals of the ETN are to obtain, generate, evaluate and disseminate information on trading programs, support regional and watershed-based trading initiatives, increase public awareness and support for trading, and facilitate implementation of programs established by state and federal environmental regulations.

Further information on the ETN organization and projects is available under "About ETN" and "ETN projects and activities".

On this website, you will find information about the latest trading news, on past and upcoming trading conferences. Current trading programs and research, state and federal trading regulations and policies can be found under their specific topic:  water quality, water quantity, greenhouse gas and wetland/ecology.
