Summary/Accomplishments (Outputs/Outcomes):
The HEI Strategic Research Plan for 2020–2025 has guided HEI’s Environment and Health Program over the past 5 years. That plan included four themes — Transport and Urban Health, Accountability, Complex Questions for the Air Pollution Mixture, and Global Health—and identified additional priorities in cross-cutting areas, including data access and transparency, evaluation of statistical methods, a focus on sensitive or vulnerable populations, and enhanced exposure assessment. The sections below briefly highlight activities in Transport and Urban Health, Accountability, and Complex Questions for the Air Pollution Mixture. Activities involving global health research have been conducted primarily by the separately funded Global Initiatives Program; a few highlights from the Global Initiatives are provided in the final section.
 Between 2020-2025, the Environment and Health Program published 13 research solicitations. Thirty-three new studies were initiated, 25 reports were published, and 12 reports were in the review and publication process by the close of the current grant period (March 31, 2025). Table 1 and Figure 1 summarize the status and reach of activities in the Environment and Health Program over the past 5 years. A detailed table of all HEI-funded studies over this period is provided in Appendix 1. Note that there are a few studies in Table 1 that fall under the global health theme. Those studies were supported with funding provided by philanthropies, development agencies, and others and provide domestically and globally relevant science that helps to inform regulatory decisions worldwide.

HEI research reports continue to be an important source to inform standards and guidelines. For example, 38 HEI reports were referenced in the most recent Integrated Science Assessments of the U.S. Environmental Protection Agency (EPA) for particulate matter, nitrogen oxides, sulfur oxides, and ozone. HEI-funded research on the effects of the clean bus program has also been cited extensively, including in the EPA Clean School Bus Program report to the Congress for Fiscal Year 2023.
HEI also tracks its reach and impact through several other indicators, including number of website visitors, number of downloads of HEI resources, and mentions of HEI’s work in print and digital media. Overall, the HEI website continues to be an effective means of providing access to HEI resources. Between April 1, 2020 – March 31, 2025, an average of 87,000 visitors accessed the HEI website each year and downloaded an average of 28,000 reports, special reports, statements, and other resources annually. HEI’s reports and data are also widely cited in the print and digital media. In the same timeframe, HEI was cited over 9,400 times in the media in more than 95 countries in more than 35 languages.
Transport and Urban Health 
 In 2022, an HEI expert panel completed its systematic review of the epidemiological evidence on the health effects of traffic-related air pollution (TRAP); highlights are shown in Figure 2. The large number of people exposed to TRAP, combined with the strength of the evidence for an association between long-term exposure to TRAP and several adverse health outcomes as revealed in this review, further bolstered the evidence that TRAP remains an important public health concern that warrants attention from the public and policymakers. 
Figure 2. Highlights from a systematic review of the epidemiological evidence for associations between long-term exposure to TRAP and selected adverse health outcomes. Outcomes for which the expert panel reported associations with high, moderate to high, or moderate confidence are shown here. Outcomes for which the overall confidence in the evidence was low to moderate, low, or very low are discussed in the panel’s report. 
  
Building on the recommendations from that systematic review, HEI issued a request for applications 
 (RFA) in 2023 and awarded funding to four studies examining the health effects of exposure to TRAP. These studies aim to create a framework for full-chain assessment of transportation systems and effects of TRAP on population health; examine associations of TRAP with lipids and other biomarkers to explore pathways that might mediate cardiovascular disease risk; assess consequences of future urban transportation landscapes on cardiometabolic health; and develop models for relating exposures from vehicle, rail, and aircraft sources to birth outcome data.  
Research funded by HEI and others has indicated that a better understanding is needed of contextual factors that might confound or modify associations between TRAP exposure and health outcomes. Accordingly, HEI funded three studies under an RFA designed to disentangle the effects of exposure to TRAP from such spatially correlated confounding or modifying factors as traffic noise, socioeconomic status, the built environment, and green space. These studies include multiple pollutants and attempt to distinguish between tailpipe and nontailpipe motor vehicle emissions and other pollution sources while incorporating information about relevant co-exposures to strengthen the evidence on health effects of TRAP in the context of spatially correlated factors.
A major challenge in epidemiological studies of long-term exposure to air pollution is the accuracy of exposure assessment, particularly for outdoor air pollutants that vary widely across space and time such as ozone, nitrogen dioxide, ultrafine particles, and chemical constituents of fine particulate matter (PM2.5). To address this gap, HEI initiated five studies under an RFA focused on applying novel approaches to improve long-term exposure assessment of outdoor air pollution. These studies aim to assess exposures to air pollution using new and conventional exposure assessment approaches, evaluate quantitative exposure measurement error to determine the added value of the novel approaches, and apply the exposure estimates in epidemiological analyses to evaluate the potential effect of exposure measurement error on health estimates. Together, these studies should provide novel insights in accounting for spatial and temporal variability in long-term outdoor air pollution exposure assessment in relation to chronic health outcomes. HEI anticipates publishing an article that provides a synthesis of the study findings and discusses lessons learned from this set of studies once they have all have been published in 2025.
Accountability 
 HEI has a long history of funding accountability research that examines the relationships between air quality actions that are intended to reduce emissions and exposure and improvements in air quality and public health (Figure 3). Accountability studies are appealing because they are the closest epidemiological equivalent to controlled experimental studies in air pollution research and thus can potentially provide supporting evidence for causal relationships. In addition, this research provides critical feedback to decision makers to ensure that they have the most relevant information for crafting effective policies. Most accountability studies to date have focused on the effects of relatively short-term, local-scale, and sometimes temporary interventions. A common challenge encountered is lack of statistical power due to small improvements in air quality or a small population that is affected by the action taken. Another issue is that findings might not be readily transferable to other locations and populations. Only a few accountability studies have sought to investigate large-scale, multiyear regulatory programs. These studies encounter particular difficulties such as making appropriate adjustments for background trends in air quality and health. Moreover, direct attribution of changes in air pollution and health to a single intervention among many regulatory actions remains difficult. Hence, HEI-funded research in this area continues to develop and apply new methods that have shown promise in addressing some of the challenges, including the use of quasi-experimental and causal inference methods.

Accountability studies completed during the current grant period showed that actions to reduce emissions from goods movements were effective in protecting people who had chronic respiratory conditions and lived near ports and goods movement corridors. Other studies showed that replacing older diesel-powered school buses resulted in improvements in school attendance and educational achievement and that enacting policies that reduce exposure to traffic emissions in a large urban area might improve birth outcomes. Another study showed that reductions in a relatively small proportion of emissions could yield a large societal health benefit while targeted emission reductions in certain transportation sectors could yield climate and health co-benefits. In addition to those completed studies, three studies in the review process evaluated major national and state air quality regulations that target power plants and mobile sources in North America and China. A fourth study underway is developing fine-scale metrics for evaluating changes in PM2.5 from various sources to support regulatory accountability and to understand the heterogeneity in air pollution exposure across the United States.
Complex Questions for the Air Pollution Mixture 
 In 2022, HEI completed a comprehensive research initiative to investigate the health effects of long-term exposure to low levels of air pollution in the United States, Canada, and Europe. The three studies in this research initiative considered associations between several pollutants—including PM2.5, nitrogen dioxide, and ozone—and a variety of health outcomes and documented positive associations between mortality and exposure to PM2.5 below the level of the annual U.S. NAAQS and current and proposed European Union limit values. Heterogeneity, however, was found in both the magnitude and shape of that association within and across the studies. HEI’s simultaneous funding and collaborations among the investigators created synergies among the teams and facilitated methodological developments and harmonization for pooled analyses. Some data have been made publicly available, thus facilitating transparency and reproducibility. All three studies addressed critical research gaps in understanding the health effects of exposure to low levels of ambient air pollution and provided policy-relevant science. 
In 2023, HEI hosted a workshop on the state of science for the health effects of particulate matter exposures. Convening thought leaders and technical experts, the workshop sought to identify critical research priorities to inform interventions or policies to protect health while integrating valuable lessons learned from the comprehensive low-exposure epidemiology research initiative. Participants discussed a variety of topics, including the biological plausibility of health effects from chronic low-dose exposure to particulate matter, the role of the indoor environment in evaluating the health effects of outdoor air pollution, the health effects of extreme air pollution events, and the changing nature of the particulate mixture due to a changing climate and transportation landscape. HEI released a new RFA based on the workshop findings in fall 2024 with funding decisions expected by summer 2025.
The COVID-19 pandemic produced unprecedented conditions that lent themselves to timely and novel air pollution research. In May 2020, only two months after the World Health Organization declared the COVID-19 outbreak a global pandemic, HEI issued an RFA for studies to investigate potential associations between air pollution, COVID-19, and human health. Four studies were funded to examine the relationship between air pollution exposure and COVID-19 incidence and associated health outcomes in several populations across North America and Europe. These studies revealed positive associations between exposure to ambient air pollution and COVID-19 outcomes, particularly in those with pre-existing conditions or low socioeconomic status. A fifth study was funded to examine the short-term changes in ambient air pollution resulting from COVID-19 lockdowns and the effects on mortality in various regions of the United States, China, Germany, and Italy that had low COVID-19 case numbers before and during the first lockdowns. The study showed that PM2.5 and nitrogen dioxide concentrations had decreased during the lockdowns — even after accounting for seasonal changes in weather — and that there were likely meaningful reductions in deaths related to air pollution because of the changes.
In 2022, HEI held a workshop to promote interdisciplinary exchange on the use of satellite-based remote sensing data in air quality monitoring, exposure assessment, and health applications. Participants explored approaches to incorporate satellite data products into large epidemiological studies and their application for studying the health effects of wildland fires. They also identified challenges, including the complexities of data assimilation and access, and pointed to a need for more communication between data providers and data users and better characterization of limitations. HEI released an RFA in early 2025 with a focus on characterizing how uncertainties and limitations in satellite-derived air quality data might affect the results of health studies.
Global Initiatives Highlights: A Separately Funded Program 
 Between 2020 and 2025, with support from philanthropic organizations and others, HEI expanded its Global Initiatives Program. In 2021, the program published the first comprehensive global estimates of contributions from the most common sources of exposure to PM2.5 and the associated burden of disease from various causes. As part of its State of Global Air platform, the program published a variety of reports and resources on topics related to air pollution and health; resources such as videos and factsheets are now available in several languages, including Hindi, Swahili, French, Russian, Spanish, and Arabic. New work was launched in Southeast Europe and East Africa, and work across South Asia was expanded with the goal of advancing research, science-policy translation, and capacity strengthening on air pollution and health in key geographies. In collaboration with the All India Institute of Medical Sciences, New Delhi, and the Indian Institute of Technology Delhi, the program initiated support for a national research network focused on air pollution and health effects research in India called the Collaborative on Air Pollution and Health Effects Research (CAPHER-India). To strengthen local research and capacity, the program is funding a research study led by India-based investigators to assess the association between exposure to air pollution and health. Targeted trainings have also been conducted to strengthen skills for early-career researchers in the design and conduct of air pollution and health studies. Under the Global Initiatives Program, much of the work is conducted in close partnership with local and regional organizations and scientific experts and is meant to complement ongoing in-country activities. For example, work in East Africa was initiated with a workshop on air pollution and health co-organized in partnership with the Stockholm Environment Institute–Africa Centre, World Resources Institute, Eastern Africa GEOHealth Hub, and AirQo. The program has also contributed to ongoing international efforts on air pollution.
