household and ambient air-pollution are associated with negative health outcomes, particularly for pregnant women and children. Although the health impacts of poor air-quality are well documented, the pathways and entry points to solutions that improve air-quality are less described, particularly for lower- and middle-income countries (LMICs). LMIC urban air-pollution Solutions (July 2019) was developed through contributions from more than 20 technical experts in an effort to aggregate the potential solutions to address air-pollution that are policy-relevant to LMICs and positively impact public health. In addition, this technical document describes the steps for approaching air-quality management, including methods for measuring air-pollution levels, identifying sources, and considering associated health impacts, and the document ends with a series of case studies to illustrate ongoing work to solve air-quality challenges.
