By 2050, the population living in major cities, especially in developing countries, will have increased twofold. With the increasing majority of the population occurring in urban areas, it is crucial to focus on how technological innovation can help to deliver a sustainable future. A sustainable city strives to create a sustainable living environment through the use of technology. Thus, the main objective of this paper is to review the impact of technological innovation on building a more sustainable city. Technological innovation has changed the overall effectiveness and benevolence over time and with regard to sustainability. A sustainable city involves development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable development encompasses all aspects of environmental stewardship, social development, and economic progress.
This review paper will be significantly important to the society in terms of building a more sustainable city especially related to economy, social and environment through the technological innovation. Organising a sustainability agenda requires at the start an interactive approach that involves public authorities, citizens and business stakeholders. This is important to obtain broader support and increase momentum. Furthermore, the study will be important to the policy makers, particularly to Ministry of Science, Technology & Innovation and City Council in developing a more sustainable plans and strategies in the future.
Cities can be classified based on the cities proper (administrative), the extent of the urban area, or the metropolitan regions . The Organisation for Economic Co-operation and Development (OECD)  also classified the size of cities based on four categories. First, a large metropolitan area has a population of 1.5 million or more. Second, the metropolitan area has a population between 500,000 and 1.5 million people. Third, a medium-sized urban area has a population of about 200,000 to 500,000 people. Fourth, a small-sized urban area has a population of about 500,000 to 200,000 people.
“The world is undergoing the largest wave of urban growth in history. More than half of the world’s population now lives in towns and cities” . From 1950 to 2010, 1.3 billion people live in small cities, 632 million people live in medium-sized cities, and 570 million people live in large cities . By 2050, the population living in cities, especially in developing countries, will have increased twofold. Thus, “the problems created by rampant urbanisation are among the most important challenges of our time. They also represent one of the greatest opportunities – and responsibilities – for the private sector. Business is uniquely positioned to shape the sustainable, economically competitive cities of the future” . With urban areas containing the increasing majority of the population, it is very important to focus on how technological innovation can help deliver a sustainable future. A smart sustainable city strives to create a sustainable living environment through the use of technology . “Transforming cities for the better through sustainable technology” .
There are several issues that pose a major impact on the quality of life that drives the shift towards a more sustainable city. First, there is a rapid rise in the number of people who move into and live in cities. Trends and lifestyle have led to the development of infrastructure and buildings, along with cultural and social practices without destroying nature and the environment. Therefore, there is a need to create a smart city by involving smart energy management, infrastructure development, waste and environment management, public-private partnerships, economic development plans, smart healthcare, and smart education programs. Second, it is a huge challenge to transform a city through sustainable technological innovation. Sometimes a city fails to recognise the challenges of the digital divide . The development of the tomorrow sustainable city must be well planned, offers services, involves the community, and includes well-linked whole systems.
Thus, the key question that has been addressed is whether technological innovation has an impact on building a sustainable city.
The first section is related to technological innovation. This section covers the overview of technological innovation and also innovation in technological change.
The second section is related to the discussion of a sustainable city. This section covers a few issues related mainly to the environment, social, and economy.
The third section covers the impact of technological innovation on building a sustainable city.
The final section discusses the conclusion and the limitations for future research.
Technological innovation involves “the introduction of something new, or a new idea, method, or device” . Sustainable development must take into account the effectiveness of the technology . Technological innovation, as part of technological change , allows organisations to test new ideas at speeds and prices that were never anticipated a decade ago . “Changes in consumption patterns can drive the creation of new technologies necessary for sustainability and their adoption and diffusion at the desired pace. Success in bringing about these changes will require substantial reorganisation of the economy and society and changes in lifestyles. Economic and financial incentives for the creation and adoption of new technologies will be needed, which may include innovative policy reforms” .
Innovation in technological change
Innovation is related to how consumers perceive an idea, a practice, a product, or an object as a new thing, and begins with consumers’ awareness of the innovation. Meanwhile, diffusion is a process in which information about the innovation is conveyed through certain channels over time among the consumers . Vergragt  discussed that innovation goes beyond invention. It refers to the spread of new technology into the wider society.
The development of technological innovation has led to the sixth generation. Rothwell  mentioned that the development of technological innovation in the first stage up to the fifth has already begun since the 1950s. The generations of innovation include technology push, market/demand pull, coupling, cross-functioning, as well as integration and networking. Hasan and Adomdza  added another generation, a sixth generation, known as design-driven innovation. It means to design new products whilst simultaneously creating a need for consumers. Technological change and sustainability are closely related to each other. Both factors form the innovation in order to improve the effectiveness of environmental stewardship, social development, and economic progress .
Transparently immersive experiences. Technology becomes more human-centric, where it will introduce transparency between people, businesses, and things. Also, the evolution of technology becomes more adaptive, contextual, and fluid within the workplace, at home, and interacting with businesses and other people.
The perceptual smart machine age. Smart technology will be the most disruptive over the next decade. This will allow organisations with smart machine technologies to harness data in order to adapt to new situations and solve problems.
The platform revolution. Emerging technology is revolutionising the concepts of how platforms can be defined and used. This includes shifting technical infrastructure to ecosystem-enabling platforms, which is laying the foundations for entirely new business models that are forming the bridge between humans and technology.
Although a research related to technology innovation has reached 100 years, the convergence of research related to science, technology, and innovation only began in 1960 . The overall technological innovation system has garnered widespread attention, especially beyond the context of sustainability. Besides technological innovation system, there have been other aspects that are related to system delineation, spatial aspects, transitions, politics, and policy recommendations .
There are two main components related to the study of innovation. First is the use of patent scale, whereby the data is used to study the geography of innovation and also the spatial extent of knowledge spillover. Second is the measuring of innovation by using survey. This refers to a set of questions that asks establishments whether a new product, process, or organisational innovation has been introduced. The questions are also related to whether the innovation is new . Reviews have been conducted on updated academic articles that were published in 2017 in order to further understand the trends of technological innovation.
One of the main problems of urban sustainability is related to energy consumption. Velmurugan , in his study, focused on the sustainable perspectives of energy consumption. The results showed that the energy saved in 1 year could be used power 60,000 European homes. In practice, manufacturers, especially, can improve energy efficiency through design and implement energy-efficient projects on their own or enter into energy performance contracting (EPC), which mainly includes shared and guaranteed savings . Also, Miao’s  study discussed the overall energy system and CO2 emission. The population scale is the most important factor in residential energy consumption and CO2 emissions.
The world has witnessed extreme environmental deterioration over the past few decades. Rapid development in urban areas has caused severe environmental pollution and ecological destruction. Green innovation is an important approach to achieve sustainable city development. There is even a relationship between legitimacy pressure, profitability, and green innovation. Green innovation will lay the foundation for balancing profit and environmental responsibility, and at the same time achieve the harmonious development of socioeconomic environmentally . The continuity of technological innovation involves green technological innovation, green institutional innovation, and green business model innovation .
Technological innovation is not just related to road management system, building management system, and public facilities management, but also to solid waste management. The problems of solid waste management include the amount and composition of waste generated, rapid expansion of urban areas, funding issues, rapid technological advancement, and limited energy and raw materials [26, 27].
To ensure the success of technological innovation, it requires a consolidation policy. Isaksson et al.  proposed layering and parallel policy-making. It is a complementary concept to understand the challenges associated with the implementation of sustainable mobility. A number of studies have also been identified to be related to policies such as environmental policies , transport policies , and policy and planning for shrinking cities .
A sustainable city means “development that meets the needs of the present without compromising the ability of future generations to meet their own needs” . In the twenty-first century, there has been a shift from sustainability assessment to smart-city goals, transformed into smart sustainable city .
The framework of a city should be holistically integrated with the urban sustainable principle . Basically, most of the literatures that have been studied so far correlated innovation and city development together. Innovation is considered as a driver of economic growth. Innovation is also an open process, with innovative organisations drawing ideas, contacts, and learning opportunities from their environment .
Environmental dimension is related to the objectives of the conservation and preservation of the environment. This includes aspects such as atmosphere, soil, water, oceans and seas, biodiversity, and sanitation.
Social dimension is related to the objective that involves the satisfaction of human needs. They include population, employment and income, health, education, housing, and security, which aim to reflect the level of education, income distribution, and living conditions.
Economic dimension is concerned with the efficiency of production processes and changes in consumption patterns.
Institutional dimension includes the ability and effort spent by governments and societies to implement changes required for an effective implementation of sustainable development.
“Cities are at the crossroads of implementing system changes for sustainable development. Paradigm shifts are needed in multiple dimensions to redefine the relations of cities with the environment” . “Cities impact their immediate environment, as well as the global environment” . According to Sharma , a sustainable city includes environmental sustainability, heritage conservation, appropriate technology, infrastructure efficiency, placemaking, social access, transit-oriented development, regional integration, human scale, and institutional integrity.
Energy consumption in urban areas is as much as 75%. It also accounts for 70% of carbon dioxide emissions. To meet the needs of the population in urban areas, infrastructure development sometimes ignores ecological sustainability. Living in urban areas has contributed to pressure on the ecosystem. Human ecological footprint has exceeded the capacity of terrestrial ecosystems for as much as 50%. The level of ecosystem services at the moment is risky at a critical level of degradation. Thus, there are five major challenges for urban sustainability. These include ecological footprint, ecosystem services and biodiversity, investment for sustainability, the good life, as well as leadership and cooperation .
So far, a number of current issues related to the environment have been published. There is a close relationship between sustainable urban development and environmental sustainability. Therefore, it is important to formulate any strategy of transformation, renewal, and regeneration. A few studies have even evaluated the environmental outcomes and effectiveness of regeneration programmes, especially in relation to green spaces, access to public transportation, climate change, and seismic-risk reduction .
Due to the high population density in the city, transport system is a key issue being discussed. Nanaki et al.  mentioned that an efficient and flexible transport system is essential for a future of low carbon transport system. Their study also found that the differences in the levels of emissions coming from the different systems of each city depict differences in the quality and utilisation of transportation networks. Carbon emissions are correlated with income. Per capita incomes are higher in a city, which results in higher average per capita demand in major emissions sources. High carbon emissions have also increased from households. By understanding that behaviours affect energy consumption will be useful in promoting low carbon household .
El Ghorab and Shalaby  discussed a green city as a new approach for planning and developing a sustainable city. Sustainable urban development appears to be closely connected with the discursive production of green city or eco-city. The implementation of sustainable urban development focuses on green infrastructure, transit-oriented development, brownfield redevelopment, and carbon reduction plan . The purpose of a green city is to strive to reduce environmental impact by reducing waste, expanding recycling, lowering emissions, and increasing housing density, while expanding open space and encouraging the development of sustainable local businesses . Thus, a number of studies have been conducted that are related to green value. A study conducted by Vyas and Jha  and Shad et al.  stated that green building construction is considered to be an essential practice to achieve sustainability. Serrao-Neumann et al.  discussed the importance of connecting land use and water planning. Ogie et al.’s  study emphasised on flood mitigation infrastructure, whereby it is crucial to remove accumulating floodwater from low-lying areas where drainage is naturally poor due to a very low slope gradient. A study by Zhang et al.  concluded that the operating efficiency, operating performance, and service quality of a drainage enterprise is determined by its sustainable development level that involves urban wastewater treatment, construction of drainage engineering, operation and maintenance, and consulting. Peng et al.  evaluated ecosystems and the impacts caused by the change in the environment. A study conducted by Thorne et al.  included wider aspects. It involves making the allocation of land for urban development more sustainable and bears an impact on food production, ecosystem services, and biodiversity conservation.

The aspect of social development towards building a more sustainable city “occurs when the formal and informal [processes, systems, structures, and relationships] actively support the capacity of current and future generations to create healthy and liveable communities”. This social aspect covers equity, diversity, quality of life, democracy and governance, and inter-connectedness .
Bertacchini and Segre  addressed two major issues about social quality in culture-led urban regeneration plans. First is a plan in terms of the instrumental involvement of the community in participation practices. Second is an urban policy that is related to the creative city notion that needs to be implemented.
Living sociability involves the city itself and a combination of culture and nature . The study conducted by Guzmán et al.  measured the link between cultural heritage management and sustainable urban development and identified three levels of a monitoring system of the management system: strategic level, operational level, and monitoring level.
If environmental and social losses resulting from economic growth turn out to be higher than economic benefits, the overall result for people’s wellbeing becomes negative.
The economic growth itself inevitably depends on its natural and social conditions. To be sustainable, it must rely on a certain amount of natural resources and services provided by nature such as pollution absorption and resource regeneration. The economic growth must be constantly nourished by the fruits of human development.
Bullock et al.  studied the economic contribution to the sustainability and efficient functioning of a city, especially the benefits in an economic context of private individual benefits and public goods benefits. First, the economic assessment focuses on the impact on businesses. Second, in terms of private benefits, transport investment provides a mixture of private and public goods benefits. The time-saving in private benefits is a key motivation. Third, for business sales, perceptions of change in sales have been found to vary by location and nature or characteristics of products. Fourth, in terms of health benefits, it includes time-saving and reduced costs of congestion, pollution, and CO2 emissions. The cycling activities provide physical exercise, which contributes to health and reduces expenditure on healthcare. Finally, in terms of time-saving and wider economic benefits, it contributes to the city’s economy by improving connectivity between journey, origin, and destination, and by reducing journey time.
The impact of technological innovation on building a sustainable city
It is very important to understand the challenges of a contemporary city. The challenge is due to the increasingly complex nature and the variety of the contemporary city . Thus, a future city needs to balance economic development with energy efficiency and the preservation of natural resources in order to improve the quality of life . “Balancing the immediate needs of today without compromising the needs of tomorrow is at the heart of being a sustainable city, and of this report” .
A study done by Van Osch and Avital  demonstrated the nature of sustainable innovation, which is sustained by the materiality, social structures, and institutional frameworks that comprise the overall sociotechnical system in which innovation takes place. The social value can be leveraged for shaping alternative courses of action, creating technological innovation, and developing novel practices that create sustainable value for society.
Han et al.  proposed the conceptual vision of a sustainable urban future in 2050. To achieve a low carbon society, various technological advances in transportation, buildings, and industries are among those that can contribute towards this end.
Kourtit et al.  proposed a roadmap for innovative strategic urban policy. This includes developing urban agglomeration as engines of creativity and technological innovation; exploiting technological opportunities and developing a sustainable urban system; laying the foundation for social cohesion and social capital; and developing ecological footprint and improve climate neutrality of urban areas.
Future urban configurations should concentrate on the efficient use of resources and opportunities in contributing to economic growth; deploying infrastructure, physical assets, and amenities; providing social services; minimising poverty, inequalities, and segments of the population; and protecting the environment and preserving natural assets .
The urban regeneration and innovation hubs for the future development, as the city transforms itself from a manufacturing centre to a knowledge, technology, and innovation centre for the nation.
The urban planning policies to strengthen the city’s identity, global competitiveness, development direction, and innovation in the living environment.
Adopting technological innovation, especially new innovative technologies, cyclical processes, and business models.
The world is undergoing an endless wave of urban growth. By 2050, the population living in cities will have increased twofold. One of the reasons that lead to this process is because a smart sustainable city strives to create a sustainable living environment through the use of technology. Technological innovation has affected effectiveness and delivered a sustainable future for city development. Thus, this paper plays a crucial role in analysing the impact of technological innovation on building a sustainable city.
The first analysis found that technological innovation has changed the overall effectiveness and benevolence with regard to sustainability. With the rapid growth of a city, technological innovation has changed the patterns of people. The use of technology has led to significant development of the sixth-generation technology. There is even a relationship between legitimacy pressure, profitability, and green innovation. Green innovation is an important approach for achieving sustainable city development. Second, a sustainable city creates an enduring way of life across environment, social, and economy. There are various aspects to redefine the relationship between city and environment. It is important to formulate strategies, transformations, renewals, and regenerations. This involves creating a green city in terms of urban form, transportation system, and energy and resources. Social aspects involve equity, diversity, quality of life, democracy and governance, and inter-connectedness. Meanwhile, the economy contributes to the sustainability and efficient functioning of a city, especially the benefits in an economic context of private individual benefits and public goods benefits. Overall, the impact of technological innovation has a positive impact on building a more sustainable city, especially in terms of environment, social, and economy. Thus, authorities, especially local government and city planners, should not neglect the importance of technological innovation.
However, this research has a few limitations. First, the preparation of this paper is based on the number of publications. Thus, it is without the field collection of primary data. Second, the lifespan of each sustainable city framework or model is not analysed. Technological change is speeding up. The pace of innovation is not just accelerating slightly, but exponentially . The problem is whether the people can rival with the speed of technological innovation. Technological innovation advancements are accelerating faster than the abilities of the people to try to adapt and use them . Also, the implementation of the framework or model for a sustainable city is usually more focused on a specific city, rather than to all cities. By adopting a sustainable model from other cities without the guided mould of a city is likely leading to a disaster. However, it is important to think global, act local.
Proposition 1: The new idea of technological innovation has an impact on building a sustainable city.
Proposition 2: The method of technological innovation has an impact on building a sustainable city.
Proposition 3: The device of technological innovation has an impact on building a sustainable city.
The research will be based on quantitative research, and a city will be chosen. Thus, we will choose Kuala Lumpur as our research city. As discussed by , Kuala Lumpur has a great policy and smart-city framework. Malaysia, as a whole, is a multi-racial, multi-religion, and multi-cultural country. One of the challenges of a city is the need to ensure economic, social, and environment sustainability now and in the medium- and long-term future. In the recent decade, researchers have discussed the importance of social sustainability within urban studies . The data collection shall involve government sectors, especially city council, residents of the city, and business sectors.
