The impact of cities on climate change is undeniable. While they occupy only 3% of the Earth’s surface, cities house over 50% of the world’s population, consume between 60% and 80% of global energy, and are responsible for 75% of carbon emissions. It is evident that any sustainability plan must start with our cities.
Rapid urbanisation and demographic pressure force cities to think beyond traditional planning methods and adopt innovative strategies that integrate urban greening and nature-based solutions. Below, we explore six standout examples of urban sustainability, leading the way towards a greener and more resilient future.
1. Madrid and the Living Walls of the M-30
In an ambitious green redevelopment project, Madrid has transformed a significant section of the M-30 motorway’s walls into an extensive living wall. Covering over 3,250 square metres and stretching across 400 metres of wall, the Living Walls of the M-30 help reduce air and noise pollution while acting as a crucial thermal regulator in one of the city’s busiest areas. The system also includes sensors to monitor air quality and pollutant capture, helping Madrid adapt to climate change and improve urban life quality(
2. Hamburg and its Green Roofs
Hamburg, Germany, has made significant strides in stormwater management with its Green Roof Strategy, where rooftops act as natural sponges. These systems capture and store rainwater, releasing it gradually to help prevent flooding. With over 140 hectares of green roofs already installed, Hamburg plans to create an additional 100 hectares, offering subsidies of up to €100,000 per project. This approach not only combats climate change but also promotes urban biodiversity(
3. Medellín and its Green Corridors
In Colombia, Medellín has transformed both its image and ecosystem through the creation of 30 green corridors. These landscaped areas reduce urban temperatures, improve air quality, and serve as refuges for biodiversity. Additionally, this project has had a positive social impact by providing employment for individuals from vulnerable backgrounds, training them as urban gardeners. This is a clear example of how green infrastructure can benefit both the environment and local communities(
4. Melbourne and its Fight Against Urban Heat
Melbourne has focused much of its sustainability plan on tackling the “urban heat island” effect. Through the Plan Melbourne 2017-2050, the city is creating new parks, forest areas, and promoting greening of buildings through green roofs and living walls. These measures not only lower temperatures but also improve water management during droughts, making Melbourne more resilient to climate change(
5. Paris and Energy Efficiency in Schools
Paris has committed to reducing the energy consumption of its public buildings by 60% by 2050, starting with the renovation of 240 schools under Energy Performance Contracts. So far, the 100 schools that have already been renovated have achieved a 33-38% reduction in energy consumption. These efforts not only help reduce emissions but also serve as an educational example for future generations on the importance of sustainability(
6. London and the Living Walls of Carnaby Street
In the heart of London, Carnaby Street is not only known for its vibrant shopping scene but also for its innovative approach to urban sustainability. In this iconic district, living walls have been installed on commercial facades, offering visitors a unique experience. These living walls improve air quality in a high-traffic pedestrian and vehicle area, contribute to thermal regulation, and support urban biodiversity. This is a clear example of how urban greening can be integrated into even the most densely developed areas(.
The Future is Green
These examples demonstrate that urban sustainability is not merely an option but an urgent necessity. Cities that adopt nature-based solutions, such as living walls, green roofs, and sustainable public spaces, are transforming the lives of their citizens and leading the fight against climate change. At Terapia Urbana, we specialise in the design and implementation of urban greening systems, including Living Walls & Urban Greening Systems, which not only beautify cities but also improve air quality and combat global warming.
Living walls are a powerful tool to enhance urban sustainability, reduce energy consumption, and create more liveable spaces
