Establish an assessment framework for risk and investment under climate change from the perspective of climate justice.

Abstract

Under the threat of climate change, the issue of climate justice has gradually received international attention in recent years. Climate justice focuses on the unfair phenomena in various regions caused by climate change. At present, some countries are facing "double inequality," that is, the reverse and separate distribution of "natural hazard" and "social resilience" and that of "risk" and "responsible input." Therefore, this study constructed a research framework for evaluating climate justice. The framework reconstructed the indicator system and conducted verification analysis on the research issues of climate justice, including the spatial correlation between "natural hazard" and "social resilience" and that between "risk" and "responsible input," and uses the "bivariate local indicators of spatial association" method to detect the regional current situation and test the justice after government's resource investment. In this way, four-quadrant spatial characteristics were obtained (high-high, low-low, high-low, and low-high districts) to identify the areas with the characteristics of climate justice. This study used Taiwan as the research area. The results show that Taiwan currently has only 7 regions with "double inequality." Therefore, only a small part of the region has "double inequality." The results can be used as the basis for future government's resource input and the allocation of climate responsibility.
