The formation of heat islands, poor air quality, loss of biodiversity and high motorisation, among others, have been aggravating pollution levels in the city of Granada for a long time. Meanwhile, the government, the regional and local administrations, and most of civil society have been disconnected from the problem. For this reason, it was decided to carry out a study on these problems and on how certain cities, both nationally and internationally, have adopted ecosystem mechanisms that contribute to the fight against climate change. In this way, an inventory of urban elements that make the green infrastructures of cities more resilient to the urban heat island phenomenon and function as a refuge for biodiversity is obtained. After several tables have been compiled, we systematise eight initial criteria for categorising spaces with ecosystem functions in three groups of urban facts, corresponding to three cartographic moments and an extra chapter: foundational trait, urban fabric, green infrastructure, and livability. With preliminary results presented, the focus would be mainly on understanding the special and urban capacity of the city to strengthen itself eco-systemically and prepare for real policies of decarbonisation and improvement of urban health and well-being.
