For example, the framework does not framework should address safer chemical select the factors to be used to determine substitution. Therefore, the committee's whether an alternative is safer than the chemical alternatives assessment framework represents a of concern because this decision is context structured approach for comparing human dependent and based on value judgments.

It could following: also include reducing exposure potential, such as by replacing an aquatic toxicant with another The goal of chemical alternatives assessments chemical that has some aquatic toxicity, but conducted using the committee's framework is breaks down quickly or has low solubility. The to identify safer alternatives that can be used to definition of "lower overall negative impact to replace chemicals of concern in products or human health and the environment" is context processes, thereby protecting and enhancing dependent and based on value judgments; human health and the environment.10 It is therefore, the selection of hazard end points for understood that the safer alternatives would comparison and their relative importance are also meet other requirements, such as cost and left to the discretion of the entity conducting performance.

This step should determine appropriate initiation of chemical alternatives assessments stakeholder engagement; identify goals, principles, for innovative green chemistry alternatives and and decision rules that will guide the assessment; sustainable designs, instead of only conducting gather information on the chemical of concern; and chemical alternatives assessments when there is determine assessment methods that will be used. a chemical of interest to replace.
