How real is the threat of imprisonment for environmental crime?

In this contribution, we investigate whether prison sentences for environmental crime are indeed used in practice, how they are used and whether they imply a real threat to violators. To this end we examine previous studies on the role of imprisonment and confront these models with some empirical data. The empirical application summarizes evidence from several countries, but focuses on detailed data for criminal prosecution of environmental legislation in Flanders (Belgium) between 2003 and 2007. Thus we are able to highlight some interesting policy issues and directions for future research
