The Clean Air Act at 50

The Clean Air Act has significantly improved U.S. air quality and public health since 1970, with benefits outweighing costs by 30-to-1 in 2020. However, the Clean Air Task Force notes that communities of color and low-income populations still suffer disproportionate pollution burdens, and the Trump Administration's rollbacks of climate and methane regulations have undermined the Act's goals.

• Since 1990, the implementation of the Clean Air Act has resulted in a 40 percent decline in fine particulate matter pollution and a 22 percent decline in ozone smog concentrations.
• An EPA study found that by 2020, the Act's reductions in ozone and fine particle pollution avoided over 230,000 premature deaths, 200,000 heart attacks, and 120,000 emergency room visits annually.
• The Act has demonstrated that economic growth and environmental protection are compatible; between 1970 and 2020, aggregate emissions of conventional air pollutants fell by 68 percent while the U.S. GDP increased by 212 percent.
• In 2020, the economic benefits of the Clean Air Act were estimated at $1.8 trillion, outweighing its $65 billion cost by a ratio of more than 30-to-1.
• Despite national progress, communities of color and lower-income populations continue to be disproportionately impacted by toxic air pollution from oil and gas development, diesel exhaust, and power plants.
• The Trump Administration carried out extensive rollbacks of the Act's goals, including the rescission of methane emission standards for the oil and gas industry, vehicle greenhouse gas standards, and the Clean Power Plan.
