We know that air pollution is associated with the development and worsening of asthma and that improving air quality can result in respiratory health gains.

The challenge associated with achieving sustained reductions in air pollutants to reduce new-onset asthma and prevent worsening symptoms in those already afflicted should not be considered an intractable one.

We have clear targets and a wealth of opportunities to effectively act and make progress.

In this review, we discuss a broad array of interventions, targeted to multiple sectors of society, with the aim to bring multiple public health benefits, in addition to air quality improvements.
