Hundreds of thousands of people in Diamaguène Sicap Mbao live squeezed between an oil refinery, an industrial zone, a busy motorway, and the smoke of an open landfill, yet not a single station measures the air they breathe. Our project changes that. Over eighteen months, we will install a network of low-cost air-quality sensors on schools, health posts, and public buildings, and publish the readings openly and for free, so anyone can see how polluted the air really is. Measuring, though, is only the start. Working with the municipality, national institutions, scientists and civil society, we will turn this evidence into action: stronger national air-quality standards, healthier future cities, and a model other Senegalese communities can adopt. Clean air should be a right, not a privilege.

In Diamaguène Sicap Mbao, one of the most pollution-exposed towns in West Africa, families breathe air that no one currently measures. Over the next eighteen months, our team will close that gap with open, reliable PM2.5 data, free for everyone. But data is only a beginning. Working hand in hand with the Mayor, national institutions, scientists, and citizens, we want this evidence to move from the sensor to the law: to modernize Senegal’s outdated air-quality standard and embed clean-air thresholds in the new cities we are building. For us, clean air is not a privilege to earn but a right worth defending.
