摘要:The deterioration of modern urban environment caused by rapid development of megalopolises is becoming increasingly important. The development of modern cities, necessitated by the need to improve the living conditions, results in the creation of new buildings and structures, the development of transport and engineering facilties. As a result, the density of built-up areas, the congestion of transport networks increases, which leads to environmental pollution and complicates the environmental situation in cities. The article is devoted to the analysis of the environement of major cities in Russia. The main factors influencing environmental pollution, characteristic only of modern cities, have been identified. The relationship between energy consumption by various industries and environmental pollution has been established. Based on a comparative analysis of harmful emissions in the most environmentally unfriendly cities of Russia, the role of urban transport in increasing the level of urban pollution is described. The main causes aggravating urban environment are indicated. These include significant high-density development development, which leads to a high concentration of harmful substances that pollute the city.
