For 50 years, the U.S. Environmental Protection Agency (EPA) has maintained its commitment to protecting public health by improving air quality and reducing air pollution. This annual report, titled Our Nation's Air, summarizes the nation's air quality status and trends through 2019. Sections of this report convey information across different time periods, depending on the underlying data sources. While some are consistently available since 1970, like growth data, our longer-term trends for air quality concentrations start in 1990, when monitoring methodologies became more consistent.
