Decisions on Complex Interdisciplinary Problems of Health and Environmental Risk (D-CIPHER) (2017-2018)
This project team aimed to improve holistic understanding of decisions about complex public health and environmental risks by generating comprehensive case study profiles on specific salient risks and related decisions. The project team brought together focused research expertise from a diverse array of disciplines to tell the story of (and reconsider) past risk-based scenarios from multiple angles.
In 2017-2018, the team focused on fluorinated chemicals. Introduced to replace toxic ammonia as a refrigerant in the 1920s, chlorofluorocarbons (CFCs) were later found to deplete the stratospheric ozone layer. Bans resulted in ozone protection, but primary replacement chemicals are potent greenhouse gases, and some may be flammable or toxic.
The team examined each “decision node” along the story arc of the risk from a variety of vantage points, considering each key decision point, assessing what was known, assumed, decided and how that determined the path forward—and how each decision might have been improved.
The team assessed the engineering and scientific dimensions of the situation; the historical context of the risk; stakeholder perspectives, media and public coverage of the risk(s); the legal and regulatory framework, including statutes, agencies, oversight and potential new regulatory policies; and economic, behavioral, cultural, ethical and sociological considerations involved in identifying and evaluating risk mitigation options.
The team developed a suite of pedagogical tools, including templates for teaching modules on the risks of CFCs using aspects of the team’s methodology and reading guides, and an infographic poster.
