Why clean air?

We all need clean air to live, grow and thrive. Yet 99% of us breathe air that is harmful and dirty, making air pollution one of our biggest health threats.

Over 8 million people die prematurely every year as a result of air pollution – more than twice as many as from malaria, tuberculosis and HIV/AIDS combined. It doesn’t have to be this way.

An urgent issue

Air pollution is everywhere and it’s getting worse. Invisible particles penetrate cells and organs in our bodies – our lungs, heart, blood and brain. Common sources of outdoor air pollution include burning fossil fuels, vehicle fumes and crop burning.

Why tackle air pollution?

By reducing air pollution, we can save and improve millions of lives. We can also tackle climate change, build fairer societies and strengthen economies.
Facts and stats
Poor air quality is bad for our health, planet and economies. Here are some statistics and facts about air pollution to help you make the case for clean air.
Health
Air pollution is a global public health problem. Every year, millions of adults and children die prematurely from poor air quality.
Climate
Burning fossil fuels causes climate change and air pollution. That’s why we need joined-up action to tackle the climate crisis and dirty air together
Economy
Dirty air imposes a heavy economic burden. Air pollution results in eye-watering health care costs and reduces businesses’ productivity. Cleaner air will help build stronger and more resilient economies.
Cities
Cities are hotspots for poor air quality and much of the world is rapidly urbanising. Improving mobility and public transport is key to clearing the air, while creating sustainable cities and communities.
Society
The burden of air pollution is unequal. Marginalised communities bear the brunt of dirty air. Improving air quality is essential for addressing racial, gender and income inequalities.
Children
Poor air quality especially affects the health and well-being of babies and children. Tackling air pollution prevents exposure during pregnancy and can avert asthma and other associated illnesses.

How can you help?

Take action
Air pollution harms the health and wellbeing of billions of people across the world. But it doesn’t have to be this way. By tackling air pollution together, we can save and improve many lives.
