The difference is the precautionary principle, applied in the EU. You can read up here: https://ensia.com/features/banned-in-europe-safe-in-the-u-s/ https://ensia.com/features/banned-in-europe-safe-in-the-u-s/ The quintessential difference is explained in this qutein this quote: "A key element of the European Union’s chemicals management and environmental protection policies — and one that clearly distinguishes the EU’s approach from that of the U.S. federal government — is what’s called the precautionary principle. 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."
