Abstract:
Of late, Asian countries have been experiencing serious environmental disasters, such as the particulate matter (PM) smog in China, a yellow sand storm in Korea, and the Fukuyama nuclear power station shutdown in Japan. Since its inauguration in 2009, the Sustainable Asia Conference (SAC) has evolved into one of the leading international conferences for coping with these environmental challenges and presenting novel and fundamental advances in sustainable development for Asia. This editorial for SAC 2015 will highlight the contents and new methodologies put forth by selected papers, presenting diverse implications in sustainable policies and business strategies.

Abstract:
We propose key performance indicators (KPIs) based on the Gross Social Feel-Good Index to evaluate a smart sustainable city and report the results of a field trial in a city located almost at the center of the Tokyo Metropolitan Area. We developed KPIs based on the following concepts: (1). The triple bottom line is the basic evaluation criteria; (2). The same unit is used for every evaluation criterion; (3). The KPIs can be used to assess a diverse range of smart sustainable cities with different goals. With the proposed KPIs of smart sustainable cities, indicators are divided into four layers for simplicity: the triple bottom line and “satisfaction” lie in the first layer. Since the notion of “society” is broad, it is further split into “safety”, “health”, and “comfort”, which are positioned in the second layer. The third layer includes indicators such as “information security” and “ubiquitous society” from the perspective of information communication technology (ICT). We conducted a trial evaluation by applying the proposed KPIs to individual ICT solutions of “Internet Protocol announcements”, “Wi-Fi around the station” and “information transmission and control” which have already been installed in a smart sustainable city.
