This work presents the formulation and pilot application of the Urban Air Quality Management Capabilities Index (CECA). This composite index offers a comprehensive and systematic analysis of a city’s capacity to formulate and implement air quality management (AQM) strategies. CECA is comprised of 31 indicators organized across nine dimensions and three components. A first component addresses technical capabilities in three dimensions including air quality measurements, understanding of emission sources, and use of modeling tools. A second component refers to data managing capabilities in the dimensions of data validation and analysis, level of data usage and dissemination. The third component is related to the enabling capabilities to lead air quality improvements. This component includes institutional, policy and regulation, and implementation potential dimensions. Each CECA indicator is calculated from the responses that local authorities give to a questionnaire. For each indicator, a specific analytical scoring scale has been defined.

CECA formulation and pilot application leaded to relevant information on the needs and possibilities for cities in Latin America to implement basic and rapid actions to reduce air pollution. Within the ten Latin American cities included in the pilot study, Mexico City and Santiago stand out for leading urban AQM capabilities. They have integrated technical knowledge into long-term AQM plans and implementation strategies. Consequently, both cities have managed to strengthen their institutions and policies to set effective command and control mechanisms, while proposing incentives for technological improvements. The group of cities with CECA intermediate and low scores evidenced that AQM is starting to emerge in the region. An essential aspect to improve across such cities is the transition to a comprehensive AQM, that goes much further than monitoring. The application of CECA on multiple cities is a way to promote an interchange of experiences along similar countries, this kind of platform has the potential to strength learning processes and promote interactions among cities in finding solutions. As a further action, CECA approach seeks to encourage urban AQM as a priority that demands a comprehensive view and multisector action at local and national scales.
