持続可能な開発におけるレバレッジ・ポイントの探索 / Exploring leverage points in sustainable development




The 2030 Agenda for Sustainable Development, adopted by the United Nations General Assembly in 2015, is a code of conduct and goal that will serve as a compass for the transition to a sustainable society in the Anthropocene, but by 2030, many countries are expected to be unable to achieve the Sustainable Development Goals (SDGs). In other words, the various sustainability initiatives that have been implemented to date around the world are not sufficient, and the global society needs to be transformed so that progress on all 17 goals can be significantly improved. But, “what does social transformation look like?” has not been clearly articulated to date.

One of the key ideas in the transition to a sustainable society is the “leverage point” (intervention point), which is seemingly small interventions in environmental and social systems, but the interventions that have the potential to have large ripple effects and even system-wide transformation. Interventions can take a variety of approaches, including the implementation of new policies, investment and technology. It is necessary to take a bird’s-eye view of the international community, taking into account various factors such as social, economic, environmental, and global/local contexts in an inclusive manner, to find appropriate leverage points, and to propose the means of transition to a sustainable society.

The purpose of this study is to clarify the relationship between the SDGs progress in the world and social, economic, and environmental factors (e.g., international flows of goods and resource consumption footprint), and to find a leverage point that will contribute to a significant improvement in progress toward the SDGs. Specifically, through a variety of analyses, including internal interaction analysis, external impact analysis, and scenario analysis, we will develop a network system model with SDG targets (indicator scores) as nodes and internal/external interactions as links, and will evaluate the progress of the SDGs and examine the effects of policies from multiple perspectives.
