Overview of the Region's Designated Air Quality Planning Organization
Pima Association of Governments’ Air Quality Planning Program develops regional air quality plans, conducts analyses to insure plans do not adversely affect air quality and ensures that air quality programs comply with all air quality requirements. With increasing concern over climate change and the role of greenhouse gases, PAG's Air Quality Planning program conducts routine emissions inventories of greenhouse gases for the region.
Clean air is essential to the economic viability and wellbeing of metropolitan Tucson, and preservation of our desert ecosystem. Motor vehicle travel, industrial activities, land development patterns and meteorological conditions all affect air quality in the Tucson region. Understanding the primary causes of air pollution and initiating steps to curb pollution are essential for maintaining healthy air.
National standards are established by the U.S. Environmental Protection Agency (EPA) to insure that our air remains healthy and to protect the visibility of our natural areas. Currently, the Tucson region meets federal health standards. However, ground-level ozone, particulate matter and carbon monoxide are of continuing concern.
