Urban air quality is deteriorating in many cities in the developing world as population, motorization, industrialization, urbanization, and other related pressures increase. This increasing air pollution poses a serious threat to human health, including increases in morbidity such as chronic bronchitis, cancer of the respiratory tract, asthma, as well as premature mortality. At the same time, there is an increasing concern about climate change, and rapidly growing urban areas are being viewed as holding opportunities to be able to reduce greenhouse gases to mitigate climate change. There is a need for an appropriate analytical framework to help choose technical, policy, economic, or other options across sectors in a manner that not only reduces local air pollution, but also provides co-benefits for climate mitigation. Additionally, these need to recognize the additional information and institutional challenges. The speaker will present an overview of urban air quality management challenges and options in developing country cities, and the framework for such co-benefits analyses. He will present case studies from India to provide a flavor of the applicability and customization of this work and the interactive tools involved.
