Apple develops framework for prioritising chemicals of concern

The framework, which it calls a Chemical Prioritisation Protocol, "adapts and extends" established methodology for chemical hazard assessment.It also adds new metrics covering specific factors relevant to the electronics industry, such as policy and social factors.The framework (see box) produces a wide range of relevant information about chemical hazard, use, exposure potential and public concern into a "simple set of quantitative indicators".  In a 2018 report that sets out the framework, Apple says that with increasing attention on the safety of materials used across products and manufacturing processes, chemical management decisions increase in complexity and scope. "The need for a data-driven methodology to support the evaluation and prioritisation of chemical substances has motivated the development of this Chemical Prioritisation Protocol," it says Unsuitable tools.The company says that existing scientific tools and policy frameworks "do not provide immediately applicable and transparent methods that companies can use to identify chemicals of concern".Apple reviewed existing prioritisation frameworks, including risk and hazard assessment methodologies, list-based screening tools, ecolabel certification criteria and public policy frameworks.
