Received: 14 September 2020; Accepted: 10 November 2020; Published: 18 November 2020 Abstract: Air pollution causes more damage to health and economy than previously understood, contributing to approximately one in six deaths globally. However, pollution reduction policies remain controversial even when proven effective and cost negative, partially because of misunderstanding and growing mistrust in science. We used an expert assessment to bridge these research–policy divides in the State of Utah, USA, combining quantitative estimates from 23 local researchers and specialists on the human health and economic costs of air pollution. Experts estimated that air pollution in Utah causes 2480 to 8000 premature deaths annually (90% confidence interval) and decreases the median life expectancy by 1.1 to 3.6 years. Economic costs of air pollution in Utah totaled $0.75 to $3.3 billion annually, up to 1.7% of the state’s gross domestic product. Though these results were generally in line with available estimates from downscaled national studies, they were met with surprise in the state legislature, where there had been an almost complete absence of quantitative health and economic cost estimates. We discuss the legislative and personal responses of Utah policy makers to these results and present a framework for increasing the assimilation of data into decision making via regional expert assessment. In conclusion, combining quantitative assessments from local experts is a responsive and cost-effective tool to increase trust and information uptake during time-sensitive policy windows.

Deaths associated with reported by the World Health Organization [7] and Our World in Data [8]. Deaths associated with COVID-19 were current on 9 October 2020. We note that each of these estimates has an uncertainty range, COVID-19 were current on 9 October 2020. We note that each of these estimates has an uncertainty but because they are compiled from different studies with different metrics of variance (e.g., standard range, but because they are compiled from different studies with different metrics of variance (e.g., deviation and confidence intervals), we show only the central estimate. standard deviation and confidence intervals), we show only the central estimate. Outdoor air pollution is the single largest contributor to pollution-related deaths, accounting for 61% of the loss of life from pollution worldwide (Figure1). Outdoor air pollution accounts for even higher proportions of the pollution burden in developed countries, where water, soil, and indoor air pollution are typically less severe [1,2,6,9]. It is estimated that 80 to 90% of outdoor air pollution is produced by fossil fuel combustion (e.g., transportation, electricity, and heating) and biomass burning Atmosphere 2020, 11, 1238 3 of 28 (e.g., heating, cooking, and fabrication) [2,9–12]. Fossil fuel and biomass burning produce primary and secondary combustion products, including particulate matter, ozone, and oxides of nitrogen, sulfur, and carbon [13–16]. The link between outdoor air pollution and health is well established for a wide range of health conditions, including cardiovascular and respiratory diseases, central nervous system disorders, psychological problems, metabolic conditions, and reproductive disfunction [17–23].
