I don't think there's a big difference among developed countries in the approach that they take.
The terms that you will hear as we continue to discuss this bill are “risk-based” and “hazard-based”.
A purely hazard-based approach looks at a substance or a group of substances and considers whether, in the abstract, the substance has characteristics that could, in some circumstance, pose a harm to the environment or to human health.
A risk-based approach starts with the hazard assessment, but then asks how the substance is used. Based on how it's used, is there an opportunity or a likelihood of exposure occurring? If there is no exposure occurring, then there is no risk, and that's a risk-based approach. It combines the hazardous characteristics of a substance with its current and possible uses.
