This thesis explores the strategies used by the chemical industry to delay, weaken, and prevent governmental regulation of industrial chemicals that pose a threat to public health. By analyzing industry engagement in regulatory processes since the 1960s, twelve different strategies have been identified that have contributed to the successful delay or weakening of policy outcomes. Using endocrine disrupting chemicals (EDCs) as a case study, this thesis further demonstrates how industry strategies are coordinated and employed in a synergistic manner. The strategies that have been identified in this paper are divided into three categories; (1) industry engagement in science, (2) industry engagement with the public, and (3) industry engagement with politics. By examining how individual strategies build off each other and are combined to achieve desired policy outcomes, this thesis demonstrates how the chemical industry’s current strategy on EDCs follows an elaborate playbook that has been developed and improved over years of regulatory engagement. Human exposure to industrial chemicals often results in adverse health effects that are gradual, ambiguous, and poorly understood. It is the complexity and uncertainty of chemical exposure science that allows industry to successfully carry out obstructive strategies and avoid public accountability. By framing the behavior of the chemicals industry in a context of violence, this thesis asserts that there are direct human health costs that result from obstructive engagement in regulatory processes.
