Today, people and organizations across various sectors, in both developed and developing countries, are committed to achieving SDGs. However, despite having goals to work towards, it is still unclear what kind of economic systems, social systems and technologies should be developed and applied to achieve these targets. From a technological viewpoint, recent discussions and movements regarding Science, Technology and Innovation (STI) have been quite narrowly focused on digital technologies, while other dimensions and fields of technologies are rarely considered. Furthermore, stereotyped views of R&D of technologies are still prevailing: that nothing is more important than R&D of advanced new technologies to increase productivity and create new products/services, which bring about further profit and economic growth. The current trend of technology choice and technology development must be changed drastically and fundamentally to one focusing on people's welfare and the environment to achieve SDGs. In this event, in order to tackle these problems, “A Comprehensive Framework on Appropriate Technology Choice for Sustainable Development” will be presented, which innovates on the concept of Appropriate Technology. The Framework consists of 10 guiding principles and is designed to be applied in both developing and developed countries. If technologies are chosen based on this framework, we believe that the majority of SDGs can be attained. In the context of a post-pandemic society, decentralized socio-economic and technological systems proposed by the framework can enhance security of our society against various risks, including future pandemics and natural disasters.
