What's in the air you breathe? Is it safe to go jogging outside today? Are your children exposed to unhealthy levels of air pollution? ClairCity is an innovative project tackling air pollution across Europe. We are involving thousands of people in six cities across the continent. We work with city councils and citizens to decide the best local options for a future with clean air and lower carbon emissions. ClairCity is funded by the European Union under grant agreement no. 689289.
