According to the first 'Impact Study of the Cornellà Natura project', the urban transformation has generated an estimated economic benefit of €218 per person per year for the health system, in addition to an average increase in life expectancy of 0.28 months per person, calculated based on increased physical activity.

The study, commissioned by the Cornellà City Council to the consultancy Healthy Cities, evaluated the evolution of health and urban environment indicators between 2017 and 2024, analyzing the impact of the 27 major actions developed in the city.

These works included the planting of 831 trees (a 4.3% increase), 65,137 shrubs, the creation of segregated cycle networks, and the improvement of green corridors. Furthermore, 12,279 m2 have been gained for pedestrians, an area larger than a football field.

The Cornellà Natura project, launched in 2016, is a strategy to make the city a greener, healthier, and more resilient space against future environmental challenges, promoting biodiversity and adapting public space to climate change.
