Pima Association of Governments is the designated air quality planning agency for eastern Pima County. PAG's Air Quality Planning Program develops regional air quality plans, analyzes air quality conformity of transportation plans and ensures that air quality programs comply with federal, state and local air quality requirements.
Clean air is essential to the economic viability of metropolitan Tucson, healthy living and preservation of the region’s desert ecosystem.
With increasing concern over climate change and the role of carbon dioxide (a greenhouse gas), PAG’s Air Quality Planning program will soon be developing an estimate of greenhouse gas emissions in the greater Tucson region. |

Air Quality Report
Map of Annual Total Pollutant On-road Emissions for 2030 (tons/year)
PAG Air Quality staff completed the gridded on-road emissions mapping for the transportation network for 2000 (shown below) and for 2030. (Maps can be found in the Air Quality Report 2007. As expected, much of the pollution is emitted along the freeways and major arterial streets due to heavy traffic and at intersections, where cars idle. Detailed information with gridded maps for individual pollutants can be found in the 2000 On-Road Mobile Source Emissions Inventory.
