This rapid literature review summarises evidence on air quality interventions in LICs and LMICs to improve air quality and/or mitigate its impacts.
The review found limited evidence derived from such countries and instead draws on evidence from reviews and compilations compiled by bodies such as Public Health England (PHE) and the World Health Organisation (WHO).
The evidence base for what works where and why is limited, inconsistent and requires further assessment. It is broadly acknowledged that cooperation across sectors and at different levels – city, regional and national – is crucial to effectively address air pollution.
An array of interventions are identified in this rapid literature review and clustered around 7 areas. It is important to note that single interventions are unlikely to have a significant impact on long-term air pollution trends, but a set of well-designed and implemented interventions can reap benefits.
