This scoping study outlines various options for methodologies that can underpin indicator(s) on the risk of (single/mixtures of) chemicals on various types of ecosystems, habitats and species. The aim of the indicator is to provide a sufficient and indicative level of information to contribute to risk governance. It can inform governmental institutions, non-governmental organizations and the general public on to what extent terrestrial ecosystems, habitats, or species, are put at risk by the occurrence of chemicals in the environment, as a consequence of human activities (e.g., farming). The report highlights the data required for the development of such an indicator and their availability through a review of existing databases. A case study illustrates the applicability of the indicator and the need for further development
