Discussion
To track the process of information technology implementation in Moscow, we turned to the reporting data of the state program «Development of the Digital Environment and Innovation». The report is presented by 8 parameters. We will consider 4 of them. To track the dynamics of development, we calculated the growth rate for each indicator.
Below is an analysis of the growth rate of personal accounts of applicants, both individuals and legal entities, relative to the indicators for 2017. The diagrams show positive dynamics. To a greater extent, this can be seen by the number of personal accounts of legal entities (in particular in 2020 and 2021). It is well known that in 2020 there was an active digitalization of all spheres of society, both ordinary people and the business sector began to apply more actively for public services and services in electronic form. The diagram shows that digitalization covers the business sphere to a greater extent.
By digitizing documents and storing them electronically, organizations can significantly reduce their paper usage. This not only saves money but also helps to reduce the environmental impact of paper production and disposal. Digital documents can be accessed from anywhere, making it easier for employees to work remotely and reducing the need for transportation to and from the office. This can help to reduce carbon emissions and promote more sustainable work practices. Digital documents take up less physical space than paper documents, reducing the need for physical storage space. This not only saves money but also reduces the environmental impact of building and maintaining storage facilities. Digital documents can be protected with advanced security measures, such as encryption and access controls. This can help to prevent unauthorized access and reduce the risk of document loss or theft [29][30][31][32][33][34][35].   Next, we demonstrate data on the share of lessons in general education organizations conducted using the services of the Moscow Electronic School project. The bar chart shows that in 2020 there was a sharp increase in the use of information technologies of the MES project, but later the growth began to decline and reached 5%. Schools can use digital textbooks, e-books, and online resources to reduce the use of paper and promote sustainable practices. This not only reduces the amount of paper waste but also helps students to develop digital literacy skills. Collaborative tools like Google Drive and Microsoft Teams can help students work together on projects without the need for paper-based documents. This not only reduces paper waste but also helps to build digital literacy and teamwork skills.  The data on the share of medical institutions connected to the unified radiological information service are presented below. The bar chart shows that by 2020, 100% of institutions are connected to the radiological information service. Wearable health monitoring devices can help to track and monitor a patient's health remotely, reducing the need for frequent visits to the doctor and lowering carbon emissions from transportation. A smart city is an innovative city that uses information and communication technologies (ICT) and other means to improve the quality of life, the efficiency of urban activities and services, as well as competitiveness, while meeting the needs of current and future generations in terms of economic, social, environmental, and cultural aspects [36][37][38][39][40][41][42][43][44][45][46][47][48][49].

Conclusion
The possible prospects of using digital and «smart» technologies of the urban environment for human development are revealed.
Also, the introduction of «smart technologies» is not affected by government programs. A positive trend was revealed in the enthusiasm of events for the development of the digital environment in Moscow in accordance with the state program «Development of the digital Environment and Innovation».
Developing smart cities presents a hopeful solution to constructing environmentally sustainable cities. By utilizing technology to gather and evaluate data, manage energy consumption, and diminish waste and contamination, cities can address the demands of their inhabitants while safeguarding the planet for generations to come.
