A Trial of Planetary and Social Boundary Evaluation of 47 Prefectures in Japan

Abstract

To achieve Safe and Just Operating Space (SJOS), considering Planetary and Social boundaries, Evaluating SJOS performance at local levels is essential. This study attempted to build an indicator database in the prefecture scale and evaluate SJOS performance and analyzed the overshoots and shortfalls based on the global threshold. The result showed that although carbon emissions and ecological footprint overshoot, most prefectures have sufficient social infrastructures. The next challenge is to fill the data gaps in the Planetary boundaries indicators and explore the localized indicators for SJOS evaluation.
