“…Consequently, this underscores the necessity of a comprehensive approach that embraces both domains to ensure an effective smart city development framework. As a comparison, a previous case study of the Municipality of Lisbon [48] focused on one aspect of policy making for future cities, air quality, using data science. Therefore, they did not examine the SDGs as a whole in their analysis (Table 14).…”

This paper aims to investigate the interlink between city sustainability development indicators and smart sustainable city indicators (SSCIs). While the sustainability development indicators of a city mostly rely on its sustainable development goals (SDGs), no investigations into whether these indicators imply SSCIs have been conducted. SSCIs are critical during the current unprecedented climate crisis and are necessary to facilitate a livable future. This study considers the city of Suwon as a case study. Suwon’s sustainable development policy adopts 10 SDGs among the 17 SDGs from the United Nations, later called Suwon SDGs (SSDGs). By conducting a content analysis, this study found that the indicators adopted from the SDGs require further investigation to evaluate the core SSCIs. Using text analytics, we found that Suwon’s policies focus on indicators in the local environment, such as the employment rates for every age category, even if the SSDG indicators incorporate the SDGs. The purpose of this analysis is to gain more attention from policymakers about the necessity of reconstructing and considering SSCIs as a part of a smart city’s sustainable development. Lessons and practical implications are discussed for future studies.

“…They can measure various air pollutants, including particulate matter (PM2.5 and PM10), volatile organic compounds (VOCs), carbon monoxide (CO), nitrogen dioxide (NO 2 ), and ozone (O 3 ), among others. Low-cost sensors have been applied in various settings, from research and citizen science initiatives to smart city infrastructural development [ 9 , 10 , 11 , 12 ]. Smart sensors can be used for the evaluation of indoor air quality, especially for measuring NO 2, O 3 , CO 2 , and CO concentrations.…”

With the development of civilisation, the awareness of the impact of versatile aerosol particles on human health and the environment is growing. New advanced materials and techniques are needed to purify the air to reduce this impact. This brings the necessity of fast and low-cost devices to evaluate the air quality from particulate and gaseous impurities, especially in a place where gas chromatography (GC) techniques are unavailable. Small portable and low-cost systems may work separately or be incorporated into devices responsible for air-cleaning processes, such as filters, smoke adsorbers, or plasma air cleaners. Given the above, this study proposes utilising a self-assembled low-cost system to evaluate air quality, which can be used in many outdoor and indoor applications. ESP32 boards with the wireless communication protocol ESP-NOW were used as the framework of the system. The concentration of aerosol particles was measured using Alphasense sensors. The concentrations of the following gases were measured: NO2, SO2, O3, CO, CO2, and H2S. The system was used to evaluate the quality of air containing tobacco smoke after passing through an actual DBD plasma reactor where the purification occurred. A high amount of reduction in aerosol particles and a reduction in the SO2 concentration were detected. An increase in the NO2 concentration was seen as an undesirable effect. The aerosol particle measurements were compared with those using a professional device (GRIMM, Hamburg, Germany), which showed the same trends in aerosol particle behaviour. The obtained results are auspicious and are a step towards producing a low-cost, efficient system for evaluating air quality as well as indoor and outdoor conditions.

In recent times the escalating pollution within densely populated metropolitan areas has emerged as a significant and pressing concern. Authorities are actively grappling with the challenge of devising solutions to promote a cleaner and more environmentally friendly urban landscapes. This paper outlines the potential of establishing a LoRa node network within a densely populated urban environment. Each LoRa node in this network is equipped with an air quality measurement sensor. This interconnected system efficiently transmits all the analyzed data to a gateway, which subsequently sends it to a server or database in real time. These data are then harnessed to create a pollution map for the corresponding area, providing users with the opportunity to assess local pollution levels and their recent variations. Furthermore, this information proves valuable when determining the optimal route between two points in the city, enabling users to select the path with the lowest pollution levels, thus enhancing the overall quality of the urban environment. This advantage contributes to alleviating congestion and reducing excessive pollution often concentrated behind buildings or on adjacent streets.
