Minimizing exposure to endocrine disruptors (EDs) is high on the political agenda, both in the EU and in the Nordic region. One tool to speed up these efforts is by regulating groups of substances. This project analysed case examples of groupings of EDs. For each case example, advantages, challenges, uncertainties and regulatory perspectives were discussed and learnings were extracted. On this basis, recommendations for grouping of EDs were developed and incorporated in a simplified workflow, which can guide grouping of EDs. Main findings were that EDs can be grouped like other chemicals, their complex hazard profiles require special attention and groupings should start with the broadest group possible. To facilitate competence building for grouping of EDs in EU regulatory process, the report was presented to chemical authorities across the EU at a webinar in November 2024.
