This article aims to explain the divergence between societal debate and biosafety legislation and presents approaches to bring both together. Main features The article reviews the development of biosafety regulations in the USA and the EU focussing on diverging concepts applied for assessing the risks of genetically modified organisms GMOs . Results The dominant environmental risk assessment methodology has been developed to answer basic questions to enable expedient decision making. As a first step methodologies that take into account complex environmental and landscape aspects should be applied. Expanding the scope of risk assessment more holistic concepts have been developed for example the Organisation for Econonomic Co-operation and Development OECD concept of systemic risks which includes socio-economic aspects. International bodies as the OECD the Convention on Biological Diversity CBD and the European Union EU have developed the Strategic Environmental Assessment SEA as an instrument that includes the additional aspects of risk assessment as demanded by many stakeholders. Interestingly there had been no attempts yet to link the existing frameworks of GMO risk assessment and SEA. Conclusions It is recommended to adapt current models of SEA to assess the systemic risks of GMOs. It is also suggested to revise the EU GMO legislation
