Transboundary environmental problems can no longer be solved by national measures alone. The cooperation of several states in an integration community such as the European Union enables the development of new solutions for such problems, which can also be of interest for other regions of the world.
The author identifies the special solution possibilities within the framework of community law and analyzes their mechanisms of action from the perspective of economic science. He condenses the results of his analysis, which is supplemented by a summary of experiences with transboundary environmental problems on the Rhine, Elbe and Euphrates rivers, into concrete policy and action recommendations. The focus is on suggestions for transboundary activities outside the governmental level.

This work also provides a general understanding of solution mechanisms for transboundary externalities. It is addressed not only to economists, but also to scholars and practitioners from other disciplines.
