The 21st century is characterized by unprecedented rates of urbanization and the challenges associated with it. According to the UN’s 2024 projections, by 2050 around 68% of the world’s population will live in cities, while cities themselves will occupy only about ~3% of the Earth’s surface. At the same time, modern megacities consume 60–80% of global energy and generate up to 75% of carbon dioxide (CO₂) emissions, making them key players in the fight against climate change and in achieving the UN Sustainable Development Goals. At the same time, rapid urban growth exacerbates social problems: about a quarter of urban residents are forced to live in slums and informal settlements without access to basic services, reflecting the global housing crisis and infrastructure inequality. These environmental and social challenges, which remain highly relevant, highlight the need to rethink the development of urban infrastructure.
Urban infrastructure—transport, housing and коммунal services, energy networks, public spaces, etc.—plays a decisive role in shaping the quality of people’s daily lives. It is infrastructure solutions that determine the comfort and safety of the urban environment, residents’ access to services, as well as the city’s environmental “footprint.” Thus, with increasing urbanization, the development of critical infrastructure (affordable housing, efficient transport, water and energy supply systems, social services) becomes an imperative for creating sustainable, safe, and inclusive cities that meet the needs of all population groups. Under these conditions, cities face the challenge of adopting a comprehensive approach to development: it is necessary to simultaneously improve living conditions, preserve the environment, and use resources rationally. As a basis for analysis, the “Life – Environment – Resources” model is proposed, linking these three dimensions of urban development into a unified framework.
Environmental Infrastructure. This term encompasses a set of natural and engineered systems aimed at environmental protection and ensuring ecological sustainability. In the context of rapid urbanization, the integration of natural elements into the urban environment has become not merely an aesthetic task, but a critically important factor in ensuring environmental well-being and quality of life. In other words, environmental infrastructure is a strategically planned network of natural and semi-natural areas, as well as specialized engineering structures, which provides a wide range of ecosystem services: air and water purification, carbon dioxide (CO₂) absorption, flood protection, recreation, etc., and protects biodiversity. The key principle is multifunctionality: each element of such a network must simultaneously perform several functions—ecological, social, and economic. In addition, the contemporary agenda of the 2020s emphasizes “nature-based solutions” and digitalization—“smart” ecosystems are emerging, equipped with sensors and software for the optimal management of green spaces, water resources, and climate adaptation. For example, in Vilnius—the European Green Capital of 2025—about 61% of the territory is covered with vegetation. The city has installed intelligent sensors to monitor the irrigation of trees and shrubs. This allows for more efficient maintenance of green areas and adaptation to climate change. The city is developing green infrastructure, reducing the share of cars, obtaining 40% of its heat from waste, and actively expanding green spaces.
Key components of environmental infrastructure:
Environmental infrastructure yields tangible benefits: in addition to improving living environments, it contributes to mitigating climate risks, for example by preventing pluvial flooding through urban parks and water bodies, improving air and water quality, and enhancing the overall standard and quality of life of urban residents. An important trend in recent years has been the effort to combine green infrastructure with traditional “grey” infrastructure (transport and engineering systems). Examples include street greening, the use of biophilic design in buildings, the creation of hybrid drainage systems, natural rain gardens, and permeable surfaces on roads and sidewalks. Innovative eco-projects are being implemented worldwide. For instance, in Milan, the “vertical forests” Bosco Verticale—residential towers covered with hundreds of trees—have been built; in Singapore, the futuristic park Gardens by the Bay with giant “supertrees” has been created; in New York, an abandoned railway line has been transformed into the elevated urban park High Line.
Social Infrastructure. Social infrastructure refers to the set of facilities and institutions that ensure normal human life, satisfy basic social and household needs, and support development and health protection. It directly affects people’s quality of life and the formation of human capital. According to urban planning standards, social infrastructure includes institutions of education, healthcare, social protection, culture, physical education and sports, as well as everyday service facilities. In other words, it encompasses schools and kindergartens, universities, hospitals, outpatient clinics and feldsher-midwife stations, social service centers, cultural centers, museums, libraries, sports facilities (stadiums, swimming pools), and other facilities without which a comfortable social life is impossible. The availability of hospitals and medicines affects the health and longevity of the population; the presence of kindergartens and schools influences birth rates and education levels; and sports and cultural facilities contribute to the comprehensive development of individuals and social cohesion.
The development of social infrastructure is a priority in many countries. Governments invest significant resources in the construction of new facilities and the modernization of existing ones, aiming to reduce the deficit of social services and improve their quality.
In Uzbekistan, a large-scale transformation of social infrastructure is underway. The volume of investments directed toward education, healthcare, social protection, culture, sports, and the urban environment is comparable to major international examples. According to the National Committee of the Republic of Uzbekistan on Statistics, in 2025, 68 new schools were commissioned in the country, while approximately 748 schools were built over the previous five years—representing one of the largest infrastructure breakthroughs in the education sector since independence. Overall, the network of general secondary education institutions has grown to 10,943 schools, which is 762 more than at the beginning of the 2020/2021 academic year, with private schools also demonstrating significant growth, their number increasing 4.5 times in recent years.
At the same time, the system of preschool education and social care is expanding. According to the UNDP report “On Improving the Care System in the Republic of Uzbekistan (2024),” the development of care infrastructure and educational institutions has been recognized as one of the key priorities of Uzbekistan’s public policy. Each new preschool facility creates not only additional places for children but also new jobs, especially for women, thereby contributing to economic growth and expanding employment in the regions.
Significant transformations are also taking place in the social protection system: new social service centers, inclusive educational institutions, rehabilitation centers, “Mehribonlik” homes, youth hubs, and multifunctional women’s centers are being established in the regions. These measures are aligned with the goals of the National Development Strategy “Uzbekistan – 2030,” as outlined in the UN Common Country Analysis, according to which the state seeks to provide the population with modern systems of social protection, healthcare, and education that meet international standards..
Innovation Infrastructure. Innovation infrastructure is understood as a set of organizations, institutions, and facilities that ensure the implementation of research and innovation activities in the economy. In other words, it is an ecosystem for the emergence, development, and support of innovations. In Uzbekistan, the term “innovation infrastructure” is закрепed in the Law of the Republic of Uzbekistan dated July 24, 2020 No. 630 “On Innovation Activity,” as well as in the Strategy for Innovative Development of the Republic of Uzbekistan for 2022–2026. It is defined as a system of institutions, organizations, and mechanisms that ensure the creation, implementation, and commercialization of innovations, as well as the development of scientific and technological entrepreneurship.
The elements of innovation infrastructure include technoparks, business incubators, technology transfer centers, venture funds, research laboratories, and digital platforms. All of them are aimed at accelerating the innovation cycle—from a scientific idea to a finished product and its entry into the market.
Official regulatory and legal acts of Uzbekistan emphasize that innovation infrastructure should provide:
Thus, innovation infrastructure is considered the foundation of technological development and the transition to a knowledge-based economy.
Special attention is paid to the creation of regional innovation ecosystems that connect universities, research institutes, IT companies, industrial enterprises, and startups. One of the most large-scale projects in recent years was the establishment of IT Park Uzbekistan in 2019, which has become a central element of the country’s digital and innovation ecosystem. Today, IT Park has branches in all regions, provides startups with incubation and acceleration services, access to technopark infrastructure, educational programs (“One Million Uzbek Coders”), as well as incentives for IT companies—thereby attracting international firms and shaping an export-oriented IT industry.
Another key element of the innovation infrastructure is the “Yashnabad” technopolis, focused on biotechnology, pharmaceuticals, new materials, instrument engineering, and energy technologies. Residents of the technopolis have access to modern laboratories, production facilities, and government support mechanisms. At the same time, the youth center “Innovatsion Markaz,” university-based technoparks (for example, Tashkent State Technical University, universities of Urgench and Samarkand), and technology transfer centers within the system of the Ministry of Higher Education, Science and Innovation are developing.
Uzbekistan is also actively introducing public-private partnership mechanisms in the field of innovation: private companies participate in the creation of technoparks, IT hubs, and research centers, as well as finance applied developments through grants, funds, and corporate accelerators. International financial institutions (the World Bank, the Asian Development Bank, the Islamic Development Bank) support reforms through Science, Technology and Innovation Development programs aimed at enhancing the capacity of universities, scientific infrastructure, and technology commercialization.
The principle of advanced development of innovation infrastructure is reflected in the Strategy for Innovative Development of the Republic of Uzbekistan for 2022–2026, approved by Presidential Decree No. UP-165 dated July 6, 2022 “On Approval of the Strategy for Innovative Development of the Republic of Uzbekistan for 2022–2026,” where innovation is considered the basis for economic modernization and increasing competitiveness in the international arena. Moreover, this approach is aligned with international sustainable development standards, in particular with UN Sustainable Development Goal No. 9 “Industry, Innovation and Infrastructure,” which emphasizes the interconnection between innovation infrastructure, sustainable industrialization, and the development of modern economies. That is why in recent years active measures have been implemented to:
It is important to understand that the success of innovation requires a comprehensive approach—technoparks alone are not sufficient without an educational base or accessible financing. Modern economies around the world strive to create full-fledged innovation ecosystems. A well-known example is Silicon Valley in the United States—a cluster of high-tech companies and startups in San Francisco that has become synonymous with a successful innovation hub. This cluster is renowned for its concentration of global IT giants and thousands of young companies, forming a community where technological trends and breakthrough ideas are constantly generated. Silicon Valley has demonstrated how effective it is for industry growth to concentrate large corporations, universities, and investors in one region, creating a synergy effect and a “magnet” for talent. Of course, it is not the only center of innovation. Similar technological hubs have emerged around the world, such as Shenzhen and the Haidian district (Beijing) in China, Bangalore in India, Tel Aviv in Israel, and Berlin and London in Europe. Many countries, including Russia, are forming innovation clusters and science cities (such as the Innopolis territory or technopolises in various regions). All these examples demonstrate the diversity of innovation infrastructure. The number of such centers is steadily growing, and each of them contributes to scientific and technological progress. Innovation infrastructure has become a cornerstone of the modern knowledge economy, and investments in it pay off through the creation of new technologies, jobs, and increased national competitiveness in the global market. At the same time, the examples provided above represent only some of the most well-known cases. In different countries, dozens and hundreds of initiatives are being implemented to support innovation and entrepreneurship. Collectively, they form a global network that drives scientific and technological progress forward.
ESG and Climate Neutrality: New Benchmarks for Urban Development
In the 2020s, ESG (Environmental, Social, Governance) has ceased to be a narrow topic of financial markets and has effectively become a common language of sustainable development. ESG is understood as a framework for assessing how an organization or territory manages environmental, social, and governance risks and opportunities. Initially, this logic was applied to companies and investors, but today it is increasingly being transferred to cities. The focus is no longer only on “green” enterprises, but also on the extent to which urban strategies, infrastructure projects, and budgetary decisions are aligned with ESG principles.
The environmental component of ESG in the urban context includes reducing greenhouse gas emissions, improving energy efficiency of buildings and transport, developing renewable energy, waste management, biodiversity protection, and the sustainable use of water and land resources. The social component focuses on the accessibility of housing, transport, healthcare, and education, reducing inequality, protecting the rights of vulnerable groups, and ensuring citizen participation in governance. The governance component concerns transparency in decision-making, anti-corruption measures, the quality of urban planning, and mechanisms for involving citizens in strategy development. Taken together, ESG in the urban dimension means that infrastructure projects must be assessed not only by economic returns, but also by their impact on nature, people, and governance quality.
This logic is also reflected in global city rankings. For example, the Arcadis Sustainable Cities Index 2022 evaluates 100 of the world’s largest cities based on 51 indicators grouped into three pillars: planet (environmental sustainability), people (social well-being), and profit (economy and governance). In essence, this is a “city ESG profile” — a balanced assessment of how a city manages resources, what quality of life it provides, and how competitive its economy is. In the latest ranking, Oslo holds the leading position, while other Northern European cities, as well as Tokyo, Seattle, San Francisco, and others, also rank highly, demonstrating that sustainability and livability are achievable across different cultural and climatic contexts.
The European Union has effectively made the ESG approach a regulatory standard for cities through the European Green Deal. This is a comprehensive strategy aimed at making the EU the first climate-neutral bloc by 2050, with a legally binding net-zero emissions target and an intermediate goal of reducing emissions by at least 55% by 2030. In 2025, the European Commission additionally proposed a benchmark of a 90% reduction in emissions by 2040 compared to 1990 levels, as a bridge between the 2030 and 2050 targets. For cities, this implies not only the need to decarbonize energy and transport systems, but also a profound transformation of building codes, water management standards, urban planning principles, and reporting systems.
A separate instrument is the EU mission “100 Climate-Neutral and Smart Cities by 2030.” A total of 112 European cities were selected, committing—on a voluntary but highly ambitious basis—to achieve climate neutrality by 2030 and to serve as “testing and innovation hubs” for others. In return, they gain access to funding under Horizon Europe, expert support, and sustainable financing instruments (green bonds, loans, ESG investments). Thus, climate neutrality and ESG criteria become a highly practical language—without clear goals, structured plans, and measurable indicators, cities cannot attract resources.
It is important to note that ESG is increasingly linked to the global sustainable finance agenda. According to UNEP FI, by 2024 more than 350 banks, representing about half of global banking assets, had joined the Principles for Responsible Banking and are gradually aligning their portfolios with the SDGs and the Paris Agreement. At the same time, climate finance is growing but remains unevenly distributed: according to the Climate Policy Initiative, developing countries benefit less from ESG investment flows and face risks and limited access to capital. For cities, this means not only setting ESG goals, but also learning how to properly “package” projects to meet the requirements of sustainable investors. This includes comprehensive infrastructure initiatives: modernization of heating networks and district heating systems, construction of energy-efficient and climate-neutral housing, development of low-carbon public transport and cycling infrastructure, implementation of water treatment and stormwater management systems, upgrading schools and hospitals with energy efficiency in mind, creation of green zones and urban parks, as well as deployment of renewable energy systems in municipal facilities. Such projects simultaneously reduce greenhouse gas emissions, increase cities’ resilience to climate risks, and create conditions for social and economic stability.
In parallel, a global movement of cities toward climate neutrality is emerging. The UN-backed Race to Zero campaign and the C40 initiative already bring together more than a thousand cities, regions, and companies that have publicly committed to achieving net-zero emissions by mid-century and to developing science-based interim targets by 2030. According to the Net Zero Tracker, by 2024 at least 343 major cities worldwide had formally set net-zero targets, collectively representing hundreds of millions of residents. This movement extends beyond Europe and includes megacities in Latin America, South and East Asia, Africa, and North America.
Global Practices of Sustainable Cities
The global landscape of sustainable cities today is highly diverse. From Scandinavian capitals to rapidly growing Indian metropolitan areas, different cities combine environmental, social, and innovation infrastructure in their own ways and “package” it within the ESG framework.
European cities largely set the tone due to a combination of ambitious climate policies and well-developed governance systems. Copenhagen (Denmark), which as early as 2009 announced its goal of becoming carbon-neutral by 2025, has built a comprehensive strategy: it has almost fully shifted district heating to centralized networks using renewable energy and waste heat recovery, constructed offshore wind farms, made cycling the primary mode of transport for nearly half of daily trips, and developed “blue-green” infrastructure to protect against heavy rainfall and improve quality of life. These actions simultaneously improve the city’s performance across all ESG components: “E” (environment and climate resilience), “S” (health, physical activity, and street safety), and “G” (long-term planning and citizen participation). Copenhagen actively participates in the EU mission on climate-neutral cities as well as in global C40 networks, spreading its practices to other cities.
In Asia, the case of Singapore—a city-state with extremely limited land area and high population density—is particularly noteworthy, as it has implemented a “City in a Garden” strategy. Nearly half of its territory is covered by vegetation, green roofs and façades are widely developed, and water management programs (NEWater, desalination, and rainwater harvesting) have transformed the country from a vulnerable water importer into a resilient system with four “national taps.” All of this is combined with strong digitalization: ICT solutions manage transport, energy networks, and water supply, and are also integrated into public urban services. In ESG terms, Singapore demonstrates how nature-based solutions and innovation can be integrated into a unified urban development strategy—from Gardens by the Bay parks to smart systems for air and water monitoring.
Alongside major capitals, examples of climate-neutral districts and neighborhoods are emerging at a smaller but highly significant scale. For instance, the German district Bahnstadt in Heidelberg was developed as one of the world’s largest passive housing projects: buildings consume about 80% less energy for heating than the conventional building stock. The district widely uses green roofs, has an extensive cycling network and smart metering systems, and is positioned as nearly carbon-neutral. In the United States, the Bryant neighborhood in Ann Arbor—previously characterized by high levels of energy poverty—became the first district in the country to declare carbon neutrality, achieved through comprehensive housing upgrades (insulation, solar panels, energy-efficient appliances) with active participation from residents and local organizations. Similar initiatives are being implemented in other countries as well, but these examples clearly demonstrate how the ESG approach can operate simultaneously at the level of buildings, communities, and municipal policy.
In the Global South, a sustainable city often also means adaptation to climate risks and “catch-up” development of basic infrastructure. The Indian city of Thiruvananthapuram adopted in 2024 a roadmap aimed at decarbonizing the construction sector and increasing the resilience of urban development to heatwaves and floods (Net Zero Carbon and Resilient Buildings – NZCRB). Measures include creating a database of the carbon footprint of construction materials, green procurement practices, and the integration of NZCRB principles, which cover approaches to the design, construction, and operation of buildings with minimal carbon emissions and enhanced climate resilience.
Another Indian city, Coimbatore, established in 2025 a City Climate Action Cell, which coordinates projects aimed at reducing emissions, expanding green spaces, and modernizing stormwater drainage systems as part of its goal to achieve net-zero by 2030.
It is important to emphasize that these cases are only the most visible examples. In practice, hundreds of cities are implementing elements of the ESG approach: from green bonds financing sustainable infrastructure projects—including metro lines, modernization of water supply and sewage systems, energy-efficient schools, and renewable energy facilities—to relocation programs from flood-prone areas, reforms of municipal enterprise governance, and digital platforms for citizen participation in decision-making.
Recent experience shows that sustainable development has long gone beyond purely environmental issues. It is about the competitiveness and survival of cities in the context of climate crisis, social polarization, and resource constraints. Environmental infrastructure forms a green-blue structure that protects cities from overheating, flooding, and system degradation. Social infrastructure ensures access to essential services, environmental well-being, and improved quality of life. Innovation infrastructure creates the foundation for technological modernization and the creation of new jobs.
ESG frameworks and climate goals, including the transition to net-zero emissions, bring these elements together into a unified strategy. The environmental component (E) reflects work with emissions, resources, and ecosystems; the social component (S) addresses issues of equity, health, and safety; and the governance component (G) reflects the ability of urban institutions to carry out transformations in a transparent and effective manner. This logic enables a shift from fragmented “green” projects to systemic urban modernization.
At the same time, sustainable cities—those that seek to combine environmental sustainability, quality of life, and efficient resource management—can take various forms. Copenhagen, Singapore, Oslo, Heidelberg, or Indian cities such as Thiruvananthapuram and Coimbatore demonstrate different development models, ranging from Scandinavian to Asian or “catch-up” pathways. However, they are united by common principles: long-term vision, data-driven decision-making, integration of environmental, social, and economic goals, and active participation of citizens and businesses.
Today, there is a wide range of best practice databases, methodologies for setting climate targets, and sustainable financing instruments. The main task is to adapt these approaches to local conditions and respond realistically to challenges such as resource constraints and social inequality. The city of the future is not only about technology or “green” architecture, but above all a balanced system in which infrastructure, governance, and society function in coordination, ensuring a decent quality of life within the ecological limits of the planet.
