Science and advanced-tech at the service of evidence-based policies
Designing the Future of Healthy, Pollution-Free Cities
When science and purpose
come together
Working for better urban environments
HARMONIE is a European project that helps cities design better policies for cleaner air, less noise, and healthier communities.
It improves how pollution is monitored, modelled, and forecast, and develops advanced tools to understand how different actions affect public health — especially for vulnerable groups such as children, the elderly, and people with respiratory conditions. These tools also assess the long-term economic and social sustainability of policies, supporting informed, evidence-based decisions.
Two environments, one vision
Impactful data for impactful results
By combining real-world insights from our pilot cities with advanced modelling from our Digital Twins, we create a continuous feedback loop between reality and simulation. Data gathered in the field — on air quality, noise, mobility, and health — feeds into the digital sphere, where scenarios can be tested, refined, and evaluated before implementation. In turn, results from these simulations guide targeted interventions on the ground, ensuring that every recommendation is both evidence-based and adapted to the unique needs of each city.
