Animal behaviour isn’t just fascinating—it also opens up important questions for chemical regulation:
🔍 Which science should inform decision-making?
📊 How do we define population-relevant effects, and which behaviour changes are population-relevant?
✅ How can we increase regulatory uptake?

The European Commission suggested it in their Chemical Strategy for Sustainability, and we are now asking them to honour their initial commitment, as no new evidence has emerged against implementing MAF.

Now is the time to start addressing mixtures in REACH, and MAF is a pragmatic, science-based method that enables us to address the fact that we are exposed to numerous chemicals simultaneously.

There is still time to sign and help us reach researchers who have not yet signed, as the deadline for signatures is June 20. After that, the signatures will be sent to the European Commission, as well as to the Ministers for the Environment.
