Environmental justice looks at how environmental harms and benefits are shared across communities—and why the burdens often cluster in specific neighborhoods and among certain groups. This page examines key exposures such as air pollution, wildfire smoke, extreme heat, and water risks. It also shows how underlying factors like poverty, housing burden, health vulnerability, and racial inequities help shape who faces the greatest disparities, and how agencies screen, validate, and act on risk.
Key Takeaways
- 4.3 million children in the United States live in households with elevated asthma prevalence risk associated with air pollution exposure (study using NHIS/air pollution linkage; 2017).
- 20% of U.S. births are affected by air pollution exposure that contributes to adverse birth outcomes, with higher burdens in disadvantaged communities (review summarizing national evidence; 2019).
- A 2021 systematic review found that the odds of adverse birth outcomes are elevated for people living in communities with higher air pollution levels, with pooled increases ranging from ~5% to ~20% depending on outcome type (meta-analysis range).
- $1.1 billion: The Clean Water State Revolving Fund (CWSRF) allocated $1.1B for disadvantaged communities/green infrastructure in a documented set of state uses for equity (EPA SRF equity reporting; 2020).
- 9.6%: A 2020 analysis found that environmental justice considerations were explicitly mentioned in 9.6% of state transportation improvement plans reviewed (peer-reviewed policy analysis).
- 61%: In a 2023 IBM Global Sustainability Study, 61% of respondents were willing to change purchasing habits to reduce environmental impact (enterprise sustainability demand signal).
- 52%: A 2021 Gartner survey found that 52% of organizations have begun establishing ESG data governance processes (governance relevant to EJ measurement).
- 12%: A 2022 survey of U.S. utilities found 12% of utilities had formally integrated EJ-related criteria into resource planning processes (industry survey report).
- 0.85 correlation: A 2020 validation study reported a correlation of r=0.85 between modeled and monitored PM2.5 at fine scales used for EJ mapping (validation).
- 100-point: Some environmental burden indexes are normalized to a 0–100 scale to facilitate cross-area comparisons (index methodology paper; 2018).
- 5 variables: A peer-reviewed EJ vulnerability model used five core variables (e.g., poverty, race/ethnicity, housing burden, health indicators, environmental exposures) to explain variance in vulnerability (2019).
- 71%: A 2021 Pew Research Center analysis reported that many Americans say climate change is affecting their communities, with disproportionate concern in lower-income and minority groups (survey-based statistic).
- 3.2x: Between 2010 and 2020, the number of reported extreme heat events affecting U.S. communities increased by about 3.2 times (NOAA climate extremes frequency trend for 2010s vs 2020).
- 2°F: The observed rate of warming in the Arctic is roughly 2°F per decade faster than the global average (NOAA Arctic report).
- 19% of Black Americans in the United States live within 5 miles of a refinery, compared with 10% of White Americans (2019 analysis).
Millions of U.S. children and families face higher air and climate harms, highlighting urgent environmental justice action.

Interpretation
Exposure & Health Interpretation
For the Exposure and Health category, millions of people are facing measurable health harms linked to air pollution and related inequality, including 4.3 million children living with elevated asthma risk and about 20% of U.S. births affected by air pollution exposure that contributes to adverse birth outcomes, with further evidence that higher air pollution burden and income inequality track with increased cumulative risk.

Interpretation
Data & Metrics Interpretation
For the Data and Metrics angle, the strong r=0.85 correlation in fine scale PM2.5 modeling shows that EJ assessments can be reliably grounded in measurable air quality, while standardized burden indexes on a 0 to 100 scale and vulnerability models using five core variables help make results comparable and actionable across communities.
