León, Guanajuato, is the third most populated municipality in Mexico, and its rapid growth has generated accelerated and dispersed territorial expansion.
In León, two of its oldest neighbourhoods, 'Barrio Arriba' and 'El Coecillo' (close to the Killian II neighbourhood), have been selected for innovative projects led by the León Urban Lab.
Lying in the valleys of central Mexico, León - with its 2.1 million residents - has experienced significant population growth in the last decade.
To fight the climate crisis, cities have to become more sustainable now. Transformations towards sustainability must be based on the specific urban characteristics of each city.
