The risk factors of various diseases for the modern urban dweller are the environmental conditions of the environment, and above all the quality of the air. The aim of this work was to generalize the environmental innovations proposed as technological solutions for air purification using plants. Methods. The modern methods of greening urban space, allowing to solve environmental problems, including air purification of cities are analyzed. Results. Modern solutions of green architecture and different approaches to landscaping elements of urban areas are considered. It is shown how vegetation provides and regulates (within certain limits) the gas composition of the air, the degree of its pollution, improves the microclimatic characteristics of urban areas, reduces the influence of the noise factor and is a source of aesthetic relaxation, increases the comfort of living conditions in the city. Conclusion. The implementation and use of the technologies considered should involve specialists in various fields, conduct educational work and solve environmental problems in practice. © 2020 Published under licence by IOP Publishing Ltd.
