Assessment, Inventory, and Modeling

The Assessment, Inventory, and Modeling (AIM) Division prepares comprehensive source emission inventories for the Bay Area and conducts air quality modeling at both regional and community scales. AIM prepares technical assessments that evaluate equity in air pollution exposures and health impacts in support of Air District programs. AIM coordinates and implements programs to improve and report estimates of emissions of criteria pollutants, toxic air contaminants, and climate forcing pollutants. AIM assesses emissions, concentrations, and exposures of toxic air contaminants, particulate matter, ozone, and their precursors, to support targeted strategies that reduce impacts of air pollution both regionally and within communities.


The Communications Office reports news and information about Air District efforts to the public and media. Communications manages behavioral outreach programs such as Spare the Air and 1-800-EXHAUST. In addition to media releases, the office publishes the Air Currents newsletter and other publications for the general public, and oversees advertising and public relations for Air District programs.

Community Protection

The Community Protection section implements the Air District’s Public Participation Plan. It facilitates community meetings, and coordinates local air improvement Spare the Air Resource Teams and youth outreach activities.

The Community Engagement section engages with the public, businesses and local governments as the Air District works to protect public health, improve air quality and protect the global climate.

Compliance and Enforcement

The Compliance and Enforcement Division helps companies comply with air quality rules and regulations by offering education, guidance, and technical assistance. The Compliance and Enforcement Division’s inspection staff checks that companies are complying with regulations and responds to complaints. When companies do not meet air quality requirements, the division takes action in proportion to the violation.


The Engineering Division evaluates permit applications and permit renewals for equipment and operations that emit air pollutants in the Air District’s jurisdiction. The division is responsible for other programs related to facilities with air quality permits, including - but not limited to - the emissions inventory and air toxics programs. The division provides technical support to other agency programs and assists businesses, trade associations, agencies, environmental groups, and community members with issues related to permitting and compliance.

Planning and Climate Protection

The Planning and Climate Protection Division quantifies and analyzes sources of air pollution and greenhouse gases, prepares plans to meet air quality standards, identifies and mitigates localized air pollution impacts through the Community Air Risk Evaluation (CARE) Program, and assists cities and counties with local air quality and climate programs including the California Environmental Quality Act (CEQA). The Planning and Climate Protection Division coordinates the integration of climate protection into Air District air quality and health plans and programs.
