Reforming EU chemical risk assessment: from regulatory bottlenecks to systems solutions

EU chemical regulation remains slow, costly, and prone to “ecological surprises” such as unforeseen negative impacts, delayed neonicotinoid bans and ongoing pollinatordecline. Current approaches create silos, overlook cumulative impacts, and trap decisions in binary “safe/unsafe” categories. A systems-first, tools-second approach can deliver faster, cheaper, and more effective decisions by prioritising simulation and systems understanding before developing regulatory tools forEnvironmental Risk Assessment (ERA). Horizon Europe’s PollinERA project demonstrates how this can work in practice: building a prototype One Systemworkflow with interoperable data and models for pollinator risk assessment; an approach that can be expanded to other environmental domains.
