This book contains six studies on various national environmental policies and environment -oriented technology policy systems in Austria, Denmark, Germany, the Netherlands, Spain, and the United Kingdom, sandwiched between this introductory and a concluding chapter. These studies were conducted as part of the ENVINNO research project, "Towards an Integration of Environmental and Ecology-Oriented Technology Policy: Stimulus and Response in Environment Related Innovation Networks", which formed part of the Targeted Social and Economic Research (TSER) Programme of Directorate-General XII of the European Commission, now 1 Directorate-General for Research. We like to thank Mrs. Genevieve Zdrojewski of GD Directorate-General Research for her kind support of our research project. The project was carried out between 1998 and 2001 by research teams from the six countries. The co-ordinating institute was the Department of Environmental Economics and Management at the Vienna University of 2 Economics and Business Administration. At this place we want to mention all researchers involved in the ENVINNO project and we want to thank them all for their contributions to this book and the project and for the good time we have had performing the project and meeting each other at regular intervals in Vienna (A), Enschede (NL), Berlin (D), and Sevilla (E).
