1.2 What are the benefits of Green Roofs and Vertical Gardens?

These urban greening solutions offer a multitude of ecological, economic, and social benefits:

• Biodiversity Enhancement: Provide new habitats for birds, insects (especially pollinators), and other small urban wildlife, counteracting habitat fragmentation.
• Stormwater Management: Absorb and filter rainwater, reducing runoff and the burden on urban drainage systems, thereby mitigating flood risks.
• Urban Heat Island Effect Mitigation: Reduce ambient air temperatures through evapotranspiration and by shading building surfaces, leading to cooler cities.
• Improved Air Quality: Plants filter air pollutants such as particulate matter, nitrogen oxides, and volatile organic compounds.
• Energy Efficiency: Insulate buildings, reducing heating needs in winter and cooling needs in summer, leading to energy savings.
• Noise Reduction: Vegetation can absorb and deflect sound, contributing to quieter urban environments.
• Aesthetic and Psychological Benefits: Enhance the visual appeal of urban spaces, promoting a sense of well-being, reducing stress, and fostering connection with nature.
