Artificial intelligence improves air quality

More than half the world's population now lives in cities And many of these cities have a problem: poor air quality. Harmful substances such as nitrogen oxides and fine dust regularly exceed legal limits, and residents – especially children and older people – suffer the health consequences, such as asthma and heart disease. This problem affects already disadvantaged groups in particular, since the air quality in poorer neighborhoods is often the worst. Reducing pollution is therefore not just an ecological issue but also a matter of social justice. Many large cities have identified the problem and developed plans for improving air quality.
