Globalisation, high tech development and environmental issues have made policy makers aware again of the possibilities of future studies for policy making. However, the lack of systematic knowledge about their impact is a major obstruction to a proper use of future studies. Especially since future studies no longer claim to predict the future, but are seen as a strategic tool for improving strategic interaction between key actors and for anticipatory policy making, insight in the dynamics of future studies is indispensable. In this article we review four future studies in the Netherlands with an eye on their methods and related impact on research in sustainable technology. Although in content the four studies were quite similar, they were complementary in linking research strategies and policy objectives.
