Green walls as a sustainable urban solution

Abstract

Green walls or vertical greenery represent an innovative approach to the integration of greenery in the urban environment. The paper will explain green walls as a sustainable urban solution. The aim of the work is to highlight the ecological, aesthetic, and functional aspects of green walls, emphasizing their contribution to air quality improvement and the visual appeal of city spaces. The paper will present concrete achievements and benefits of the implementation of green walls worldwide, the percentage of green areas in cities, and legal regulations defining a certain percentage of green areas with the goal of reducing the effects of greenhouse gases. At the recently held COP28 conference in the United Arab Emirates, the focus was on climate change and planetary warming caused by the effects of greenhouse gases such as carbon dioxide from burning fossil fuels for energy. In addition to reducing fossil fuels and exploring alternative energy sources, minimizing harmful gases can also positively impact the increased presence of green areas in urban spaces, a topic further discussed in the paper itself.
