Sustainable urban infrastructure expands on the concept of urban infrastructure by adding the sustainability element with the expectation of improved and more resilient urban development. In the construction and physical and organizational structures that enable cities to function, sustainability also aims to meet the needs of the present generation without compromising the capabilities of the future generations. SDG 9, of the international Sustainable Development Goals set by the United Nations General Assembly, deals with infrastructure, however, infrastructure is a building block for the rest of the SDGs. Therefore, the achievement of sustainable infrastructure is of significant concern in multiple areas of society. The sustainable development of urban areas is crucial since more than 56% of the world's population lives in cities. Cities are in the lead of climate action, while being responsible for an estimated 75% of the world's carbon emissions.

The increasing population of China has significantly impacted the ratio of resource consumption to resource production, which has put pressure on the Chinese government and economy to establish a more efficient way of using resources to permit sustained longevity of Chinese society. The Circular Economy Policy has already begun to address this issue by enforcing repeated analysis and reuse throughout a product's entire life cycle. To solve this problem, first of all, China will improve to promote the progress of science and technology and business management and improve labor efficiency. The second is to guide enterprises to optimize the combination of production factors following market needs and achieve the interface between production and demand. Thirdly the government will allow competition and the mechanism of eliminating winners and losers among enterprises to enhance the ability to produce and operate goods. Last but not least, the Chinese government plans modern urban centers in completely different areas. A modern framework includes open transportation, water supply, and distinctive private regions and mechanical regions dissemination. First world and developed countries, such as some parts of China, often seek to grow exponentially in economic productivity and consumerism, but this exponential growth must be matched with an exponential drop in resource consumption that may be achieved through an integrated system approach. This systematic approach of incorporating consumerist and lifestyle changes on many societal levels, reflects the systematic dynamic of sustainable urban infrastructure. By treating sustainability as a function of interconnected systems (e. g. transportation, land development, community formation, etc. ), the impact of any change in one system can be amplified without causing a sector of infrastructure to singularly fail.

Roadside and urban infrastructures such as signposts, bollards, and street furniture are prone to damage and deterioration. As infrastructure deteriorates, it requires either replacement or enhancement. Existing public funding sources are inadequate to meet these needs. Self healing technology could protect surrounding paving and foundations from damage when items of infrastructure are impacted, which can reduce maintenance and improve the sustainability of urban developments. Self healing developments result in zero waste and zero landfill from maintenance on items of urban infrastructure for the life of the development.

Policy and technology are key factors in the implementation of renewable energy sources, which not only improve energy efficiency, but also the electricity demand of communication networks and the self sufficiency of a city in the instance of disaster. Projects that involve zero energy buildings, reduced cooling and heating demand, and greater understanding of occupant behavior achieve a greater holistic perspective of wasteful energy sourcing.

Distributed generation and energy demand management are components of the smart grid, a term for an electrical grid that uses renewable and energy efficient means of generation. An optimized city might also use the smart grid for communication networks, the Internet, and other electronic signals that build the electronic and cultural infrastructure of urban communities. Electric vehicles and substations link transportation with the grid, and commercial transactions over the Internet directly link the economy. As cities grow larger and more electronically dependent, reliability and security become significant concerns for institutions and private citizens. By using a renewable and efficient system, a city can reduce the threat of a collapse of power and information services.

A common governance and administration method subjected to studies, such as from the Complex and Sustainable Urban Networks (CSUN) Laboratory at the University of Illinois at Chicago, is the control of resource supply and demand. When supply and demand are manipulated, it may be possible to steer an urban society toward resources and forms of infrastructure that are more conservatively used and conducive towards sustained use. In addition, by systematically designing interdependencies and multifunctionality among forms of urban infrastructure, a society ensures that, if one part of infrastructure fails, other parts can help remediate the loss in service. This references back to integrative design as well. Life cycle assessments of resource materials can also help calculate the environmental footprint of a city. In 2017, at least 84 sampled cities from around the globe had a projected footprint increase of 58% 116% by 2050. If the cities reduced resource consumption on a social and technical basis, and adopted energy efficient practices, the projected footprint improved dramatically. Unfortunately, these statistics are often difficult to compare because the exact conditions, resources, and assets of the cities all differed. The countries are more relatable, however, when globally valued resources are used, thus encouraging international dialogue, planning and foresight.
