Reappraising the public health benefits conferred by environmental policy: Considerations for an aging society.

Although addressing environmental pollution and unprecedented societal aging are concurrent public health challenges, rarely is the relationship between the two considered. Current approaches to valuing the public health benefits conferred by environmental policy may be ill-suited to aging populations. We describe the limitations of the age-invariant approach used by the United States Environmental Protection Agency to estimate the public health benefits corresponding to environmental regulation. These include the poor age-representativeness of the samples informing the valuation of mortality risk reduction, the exclusion of age-related outcomes from valuation, and the omission of age-related third-party expenditures. We offer an empirical framework that could address these limitations. Our recommendations could improve the calibration of environmental regulatory analysis to the changing age distribution of the United States population.
