Smart cities utilize digital innovations to address urban challenges and ensure sustainable urban living. Discover vital multidisciplinary research on this subject matter ranging from communications technology to intelligent energy management systems.
New York City is using sensors to monitor air quality, reduce energy usage and enhance waste collection efficiency. Furthermore, residents have access to various apps that allow them to report issues related to city infrastructure.
Copenhagen
Copenhagen, Denmark has become a living lab for smart city technologies with over 250 companies and start-ups involved in developing products and services for smart cities. Attractive government funding opportunities exist here while early adopters of digital solutions enjoy strong citizen involvement with urban planning processes.
Automation is one of the key tools for smart city operations, enabling cities to respond immediately to real-time data from IoT sources such as sensors. Automated systems may switch off streetlights when no one is around – saving energy while supporting sustainability efforts.
Greater Copenhagen is an internationally acclaimed centre for smart city development, boasting high levels of personal safety, narrow wealth gaps, excellent public transportation options and cycling infrastructure, numerous digital initiatives and many leading-edge public policies. Furthermore, Denmark stands out as an efficient business location with flexible labour market regulation, qualified talent pool access, favorable taxation structures and quick establishment procedures making it one of the cost-efficient places in Europe to do business.
Amsterdam
Amsterdam, Netherlands, is well known for its tolerance and progressive outlook. Citizens there have developed a comprehensive plan to meet sustainability goals including using smart technologies to reduce commute times, traffic congestion and pollution levels.
One project involved developing an online platform to allow residents to purchase goods at their true “true price,” sparking discussion on the hidden environmental and social costs associated with daily goods. Another initiative addressed energy usage; residents were enabled to generate electricity from solar panels.
Amsterdam InChange is an open-source innovation platform providing entrepreneurs, startups and citizens a digital marketplace to transform their ideas into projects designed to improve livability and economic prosperity within their city. At present there are over 250 projects currently in various stages of development, piloting or implementation; 16 focus specifically on greening mobility systems while other projects address working and living aspects, including three aimed at streamlining electricity consumption by equipping residents with smart meters with online monitoring/control (see Austin).
Tokyo
Tokyo demonstrates how sustainable technology and dense urban living can work hand in hand to effectively manage megacities. Integrating environmental, energy efficiency, and digital infrastructure into governance structures and public service operations is vital to achieving operational excellence and improving residents’ quality of life.
Smart-city technologies in this city help optimize both traffic management and waste disposal, with big data analytics and AI systems monitoring air quality, water usage and energy consumption as well as IoT devices allowing citizens to easily access online services quickly.
Innovative technologies like piezoelectric power generation help lower the costs associated with creating a greener and more energy-efficient city. Cities like Spain can easily implement such technologies on Cloud Studio IoT’s low-code platform to gain energy savings and lower CO2 emissions.
Singapore
The Global Centre defines smart cities as urban areas which use innovation – be it technology, different ways of working practices or natural-based solutions – to enhance quality of life and prosperity among their citizens while increasing sustainability, inclusivity and citizen participation in their urban environment.
Singapore stands out as an exceptional city-state that successfully fosters innovation through strong political will, robust infrastructure and collaborative approaches to problem-solving. Additionally, its small size makes digital transformation simpler to implement.
As COVID-19 spreads, the Global Centre has assisted UNDP Country Offices in their efforts to implement and scale-up smart city initiatives by offering technical helpdesk support and sharing knowledge. We aim to ensure smart city projects are led by people for people, with appropriate technology supporting desired outcomes.
