As cities across the globe face population growth and space scarcity, the development of green infrastructure in urban environments has the potential to protect buildings against extreme weather. Aiming to develop a local approach to respond to this global challenge, Arup worked together with the Subdirectorate General for Energy and Climate Change of the Madrid City Council to prepare the Madrid + Natural report – a series of guidelines to tackle climate change through multiple local solutions.
This forward-thinking report highlights the importance of greening buildings, infrastructure and open spaces in Madrid and proposes strategies to integrate nature into the urban fabric as a tool to address climate change, reinvigorate neighbourhoods, and improve wellbeing of dwellers.
From this collaborative work, Arup and the Madrid City Council created a framework of nature-based solutions, adapted to the real needs of cities, to increase resilience and improve livability for residents.
Project Summary
16 urban solutions
-4.5ºCin summertime
40% cooling savings in buildings
Greening and reusing existing infrastructure
Making existing infrastructure greener – from transport hubs and empty spaces to obsolete infrastructure – has the potential to reduce cities’ carbon footprint , creating more natural habitats for wildlife and more recreational spaces for residents.


16 solutions to creating green cities
Arup’s sustainability experts created a framework of 16 nature based solutions that operate at three different scales: city, neighbourhoods and buildings; all key to increasing resilience and climate change adaptation towards building a more sustainable future for the city of Madrid.
The 16 solutions use nature as a source to regulate Madrid's urban environment and respond to problems such as pollution, increased high winds and rainfall, periods of very high temperatures and the loss of local biodiversity. From designing sustainable roofs and using resilient urban planning to restoring riverbanks and creating urban forests, the report proposes achievable solutions to designing healthier, liveable, and resilient urban areas.
