Take a moment to recognize how public health achievements, such as The Clean Air Act, have improved our daily lives, safeguarded our families, expanded our life spans, and strengthened our communities.
Ready: The Clean Air Act, passed in 1970 and strengthened in 1990, made clean air a national priority. Instead of leaving pollution control up to local areas, it created a shared responsibility across federal and state governments based on public health science.
Set: The law put systems in place to actually reduce pollution, like setting limits on air quality, requiring permits and enforcing rules. These protections made cleaner air the norm, not just a goal and led to long-term reductions in harmful pollutants like smog and fine particles.
Action: Air pollution still doesn’t affect everyone equally. Communities near highways and industrial areas, often low-income communities and communities of color, face higher exposure. Next steps include strengthening standards, improving monitoring in these areas and making sure we continue measuring and funding the health benefits of clean air.
Health Outcomes Impact: By 2020, the Clean Air Act was estimated to prevent over 230,000 early deaths each year, along with millions of cases of illness and missed days of work and school.
