My understanding is that most European regulators err on the side of caution with respect to banning chemicals. It's more of a "you have to prove this is safe" mentality, rather than "you have to prove this is dangerous" in terms of the scientific uncertainty. They're all looking at the same global set of available research data it seems:

> "This principle, in the words of the European Commission, “aims at ensuring a higher level of environmental protection through preventative” decision-making. In other words, it says that when there is substantial, credible evidence of danger to human or environmental health, protective action should be taken despite continuing scientific uncertainty. In contrast, the U.S. federal government’s approach to chemicals management sets a very high bar for the proof of harm that must be demonstrated before regulatory action is taken."
