Why It Matters
The rollback threatens public‑health gains, deepens inequities, and could cost billions in health‑care expenses.
Key Takeaways
- •EPA deregulation threatens vulnerable communities.
- •Air pollution raises mortality even below current standards.
- •Cleaner air policies have proven health benefits.
- •Low‑income, minority neighborhoods face disproportionate exposure.
- •Climate change may cause 14.5 million deaths by 2050.
Pulse Analysis
The Biden administration’s recent decision to rescind the 2009 EPA endangerment finding marks the most sweeping deregulatory move in U.S. environmental history. By stripping the Clean Air Act of its authority to curb carbon dioxide and co‑pollutants, the White House frames the change as a $1.3 trillion savings, yet the real cost will be measured in public‑health outcomes. This policy shift reopens a legal gap that previously forced power plants, vehicles and industrial facilities to limit emissions, a gap that disproportionately protects affluent suburbs while leaving high‑exposure neighborhoods exposed.
Decades of epidemiological research confirm that fine particulate matter (PM2.5), nitrogen oxides, sulfur dioxide and ozone precursors are linked to premature death, asthma attacks, cardiovascular events, and adverse birth outcomes. Landmark studies such as the Harvard Six Cities cohort and the American Cancer Society analysis demonstrate a clear dose‑response relationship, even at concentrations below current standards. The burden falls hardest on communities situated near highways, ports, refineries and aging power plants—areas that are often low‑income and home to people of color due to historic segregation and disinvestment. These environmental injustices translate into measurable gaps in life expectancy and health‑care costs.
Future projections underscore the urgency: the World Economic Forum estimates climate‑related health impacts could claim 14.5 million lives and generate $12.5 trillion in economic losses by 2050, with the U.S. health system absorbing an extra $1.1 trillion. Conversely, past interventions—traffic reductions during the 1996 Atlanta Olympics, nationwide particulate controls, and the retirement of coal plants—have already added months to average lifespans and cut hospital admissions. Maintaining and strengthening air‑quality regulations therefore represents a high‑impact, cost‑effective public‑health strategy that safeguards equity while delivering tangible economic returns.

The White House has announced plans this week to rescind the 2009 endangerment finding that climate change poses a threat to the public. This action will remove the EPA’s authority to regulate carbon dioxide and other greenhouse gases under the Clean Air Act. The move is being framed as the “largest deregulatory action in American history,” with claims that it will save Americans $1.3 trillion in “crushing regulations.”
But stripped of political rhetoric, this decision is not about savings. It is about who really bears the cost of air pollution. If the EPA weakens federal standards on power plants, vehicles and industry, the cost will fall on you and me and our communities. And it will be measured not in dollars saved, but in asthma attacks, heat‑stroke deaths, pregnancy complications, lost homes and shortened lives.
As a health‑equity researcher, I rely on evidence. Decades of longitudinal research show that long‑term exposure to air pollution shortens lives. One of the most influential studies, the Harvard Six Cities Study, followed residents over many years and found that those living in more polluted cities had significantly higher mortality rates. The American Cancer Society cohort study tracked hundreds of thousands of adults and demonstrated that long‑term exposure to fine particulate matter increases the risk of cardiopulmonary mortality and lung cancer. More recent analyses involving tens of millions of Medicare beneficiaries show that even pollution levels below current regulatory standards are associated with increased mortality risk.
The combustion of fossil fuels releases carbon dioxide along with a complex mixture of harmful co‑pollutants — fine particulate matter (PM2.5), nitrogen oxides, sulfur dioxide, and ozone precursors. These pollutants, that are smaller than the width of a single hair strand, are inhaled deep into the lungs, where they trigger inflammation and enter the bloodstream, affecting nearly every organ system. Over time, this increases the risk of asthma, chronic obstructive pulmonary disease, heart attack, stroke, diabetes, adverse birth outcomes and cognitive decline.
Those harms will fall hardest on communities located near highways, ports, refineries and power plants — places that already face higher cumulative pollution exposures. Many of these neighborhoods are lower‑income, home to older adults and workers in high‑exposure industries and disproportionately communities of color shaped by decades of residential segregation and disinvestment.
These individual risks scale quickly. A recent World Economic Forum analysis estimates that by 2050, climate change could contribute to an additional 14.5 million deaths worldwide and $12.5 trillion in economic losses, with healthcare systems facing an added $1.1 trillion burden. These are not abstract projections. They reflect the cumulative impact of heat, air pollution, extreme weather and disrupted systems on human health.
And we also know something equally important: when emissions decline, health improves. Studies, summarized in the EPA’s second prospective report, proved that regulatory interventions and energy transitions resulted in measurable reductions in mortality and hospitalizations following improvements in air quality.
The Evidence: When Air Gets Cleaner, People Live Longer
-
1996 Atlanta Olympics Traffic Reduction – Temporary traffic restrictions reduced ozone levels and were associated with nearly a 40 % decline in asthma‑related emergency visits among children.
-
Controls on Air Pollution – Controls on fine particle pollution extended average lifespan in the United States by five months between 1980 and 2000.
-
Coal Plant Retirements – After eight power plants in California closed between 2001 and 2011, a measurable decline in fine particulate pollution, improved birth outcomes and reductions in respiratory hospitalizations were found.
Public health is rooted in prevention. We act when strong evidence shows that exposure causes harm. On air pollution, the data has been clear for decades.
Cleaner air is a public‑health intervention. And for all of us—our parents, children, communities and especially the most vulnerable among us—it is a lifeline.
