The use of alternatives assessment in chemicals management policies: Needs for greater impact.

Alternatives assessment is a methodology used to identify, evaluate, and compare potential chemical and nonchemical solutions with a substance of concern. It is required in several chemicals management regulatory frameworks, with the objective of supporting the transition to safer chemistry and avoiding regrettable substitutions. Using expert input from symposium presentations and a discussion group hosted by the Association for the Advancement of Alternatives Assessment, four case examples of the use of alternatives assessment in regulatory frameworks were evaluated and compared: (1) the US Environmental Protection Agency Significant New Alternatives Policy (USEPA SNAP), (2) authorization provisions in the EU REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals) regulation, (3) the California (CA) Safer Consumer Products (SCP) Program, and (4) the Safer Products for Washington (WA) Program. Factors such as the purpose of the alternatives assessment, the timeline of actions, who completes the assessment, the role of stakeholder engagement, and the regulatory response options for each policy are outlined. Through these presentations and expert discussions, four lessons learned about the use of alternatives assessments in regulatory policy emerged: (1) the goal and purpose of the regulatory framework significantly affects its ability to result in safer substitution, (2) existing frameworks struggle with data access and insufficient stakeholder engagement, (3) some frameworks lack clear decision rules regarding what is a safer and feasible alternative, and (4) regulatory response options provide limited authority for enforcement and do not adequately address options where alternatives are unavailable or limited. Five recommendations address these lessons as well as how the application of alternatives assessment in regulatory settings could have greater impact in the future. This synthesis is not meant to be a comprehensive policy analysis, but rather an assessment based on the perspectives from experts in the field, which should be supplemented by formal policy analysis as policies are implemented over time.

Advancing alternatives assessment for safer chemical substitution: A research and practice agenda.

Alternatives assessment has emerged as a science policy field that supports the evaluation and adoption of safer chemistries in manufacturing processes and consumer products. The recent surge in the development and practice of alternatives assessment has revealed notable methodological challenges. Spurred by this need, we convened an informal community of practice comprising industry experts, academics, and scientists within government and nongovernmental organizations to prioritize a research and practice agenda for the next 5 years that, if implemented, would significantly advance the field of alternatives assessment. With input from over 40 experts, the agenda outlines specific needs to advance methods, tools, and guidance in 5 critical areas: hazard assessment, comparative exposure characterization, life cycle considerations, decision making, and professional practice. Fifteen research and practice needs were identified, ranging from relatively simple efforts to define a minimum hazard data set to the development of more complex performance and decision-analytic methods and data integration tools. Some research needs involve adapting existing approaches to the alternatives assessment context, while others will require the development of entirely new methods and tools. The proposed research and practice agenda is ambitious. Implementing it will require expanding the current network of researchers from academia, government, and industry, as well as increased funding for methodological, application, and evaluation research.

Lessons from the 2018 International Symposium on Alternatives Assessment: Advances and Reflections on Practice and Ongoing Needs to Build the Field.

Alternatives assessment is gaining traction as a systematic method to support the informed substitution of chemicals of concern. The 2nd International Symposium on Alternatives Assessment, on 1-2 November 2018, convened nearly 150 professionals from government agencies, industry, consultant firms, academia, and advocacy organizations to advance a greater understanding of the evolving methods, practices, and challenges in the use of alternatives assessment. This article reviews highlights and lessons from the symposium, including 1) notable advances in methods, 2) shared insights from practitioners on best practices as well as inherent tensions and challenges, and 3) research and practice needs in the field that can be addressed by organizations such as the newly launched Association for the Advancement of Alternatives Assessment. Being interdisciplinary in nature, the establishment of educational frameworks across disciplines and inclusion of diverse expertise in hazard and exposure assessments, life cycle impacts considerations, design principles, and economic and engineering evaluations will ensure continued growth of the field.
