Why clean air

The air around us
is part of our health.

Prevention starts in everyday places: the home, the school, the playground and the workplace.

A preventable health risk

WHO identifies ambient air pollution as a contributor to cardiovascular and respiratory disease and lung cancer. Reducing exposure is a public-health objective, even where effects cannot be traced to a particular individual.

Children deserve deliberate protection

Children’s lungs and other organs are still developing. Their activity patterns and breathing rates affect exposure. The EEA describes risks to lung development, asthma and birth outcomes, alongside emerging evidence on brain development.

That makes schools, homes and routes between them important settings for prevention. Protection also needs to reach older people, people living with illness and communities facing greater exposure or fewer choices.

Different outcomes. Different strengths of evidence.

We will assess each pollutant, exposure period, population and health outcome separately. An association means two things occur together; it does not by itself establish that one causes the other. A probable causal relationship requires stronger, converging evidence. An established causal conclusion requires a robust body of evidence assessed for alternative explanations.

Health areaHow we will communicate it
Cardiovascular disease, stroke, respiratory disease, COPD, lung cancer and mortalityCore health concerns supported by major evidence assessments. We will use the causal classification and exposure definition of the chosen assessment, rather than assign a single label to every pollutant.
Asthma, respiratory development, pregnancy and birth outcomes, allergiesImportant public-health concerns. We will distinguish disease onset from symptom exacerbation, and specify where evidence varies by endpoint and pollutant.
Cognition, neurological development and mental healthResearch priorities requiring endpoint-specific review. We make no general causal claim and include no projected benefits for these endpoints in our founding impact model.

Concentration is not the same as exposure

A monitor measures pollutant concentration at a place and time. Personal exposure also depends on where someone spends time, indoor conditions and movement. We will label fixed-site concentrations as such and validate any estimates of personal exposure.

A short-lived peak cannot simply be compared with an annual limit. A local observation cannot by itself identify a source, prove a legal breach or diagnose a person’s illness.
