Where We Are Heading There is no denying that one key concern of smart ci�es is environmental sustainability. The carbon footprints of ci�es dominate the total emissions of the country. This means by using advanced technology, we can start
shaping ci�es so that they are be�er equipped to address today’s urban challenges which, unless managed well, can have a nega�ve impact on the environment and the quality of life for urban communi�es.
Reduce Carbon Emissions The adop�on of low-carbon technologies and applica�ons is useful to tackle the iden�fied needs of reducing the emissions of greenhouse gases, exploi�ng the poten�al of new renewable technologies and reinforcing their public acceptance • Renewable Energies The Intergovernmental Panel on Climate Change report iden�fies nuclear, wind, solar, �dal, geothermal and hydroelectricity in suitable loca�ons as technologies that can provide electricity with less than 5% of the lifecycle greenhouse gas emissions of coal power • Alterna�ve mobility Smart bike-riding services which allow users to unlock dedicated bikes located all over the city via an app on their phones, smart-ride sharing and self-driving, autonomous vehicles which use less fuel • Carbon Capture, U�lisa�on, and Storage (CCUS) Carbon Capture, U�lisa�on, and Storage (CCUS) encompass methods and technologies to remove CO2 from the fuel gas and from the atmosphere, followed by recycling the CO2 for u�lisa�on and determining safe and permanent storage op�ons • Low Carbon Building Material A building’s overall embodied carbon is inextricably linked to the composi�on of the products from which it is built. The manufacture of materials like steel, concrete, aluminium and glass for use in building construc�on accounts for 11% of global carbon dioxide emissions. Use of carbon-friendly building materials from blast furnace slag, mature bamboo, natural clay and crushed basalt, rice straw, recycled high-density polystyrene, wood fiber for low embodied carbon
Urban Solid Waste Management • Smart waste solu�ons are already a reality. The solar-powered trash compactors, for instance, use smart sensors to know when to begin compac�ng • The containers communicate with local waste management organisa�on via cloud to signal when they need to be emp�ed. This reduces the ac�vity of garbage trucks, thus reducing their carbon footprint and harmful emissions
• Systems have been developed which leverage new technologies such as Internet of things (IoT) connec�vity, big data, machine learning and analy�cs to gather energy and environment data, including: Real-�me Monitoring and Management of Energy and Environment
- air pollu�on levels - how much water is being wasted - renewable energy performance - solid waste measurements
• The data is collected via sensors and cameras placed in strategic places, like on solar panels on top of buildings or garbage bins across the city. City officials and ci�zens alike can access and use this informa�on to make informed, more conscious decisions and iden�fy new opportuni�es which can ul�mately lead to improved air quality, less energy use and a cleaner city
Support Energy Efficiency Programmes • Smart LED street lights, which last longer and require less energy to operate. What’s more, they can be dimmed or brightened based on the loca�on and �me of day to ensure efficiency without compromising safety • Some smart lights can even automa�cally turn off when they don’t detect any ac�vity on the street. • Implemen�ng energy-efficient IoT systems like GPS, cameras and traffic light coordina�on systems to regulate traffic is another way smart ci�es can save energy
