The potential negative impact of the UNFCCC: An analysis of sectoral, geographical, and temporal problem shifts from climate policies and measures in 25 industrialized countries
分析了1994至2023年间25个发达国家提交的182份国家通报，发现气候减缓措施引发了718次问题转移风险，对发展中国家造成不成比例的跨部门、跨区域和跨代际影响，呼吁采取整体性方法避免意外后果。
• Climate mitigation measures have been accompanying problem-shifts since 1992. • We provide a novel framework to identify problem-shifts. • We draw on 182 national communications from 25 developed countries. • Problem-shifts create 1,749 impacts on 8 sectors, including in the Global South. • Temporal impact entails reduced solution space in the future. Climate mitigation policies and measures, while well-intentioned, can generate unintended consequences—a phenomenon known as ‘problem-shifting’, where efforts to curb climate change inadvertently create new environmental or socio-economic challenges. Although issues such as carbon leakage have been acknowledged under the United Nations Framework Convention on Climate Change, no systematic analysis has examined the magnitude and direction of these shifts. This study analyzes 182 national communications submitted by 25 Global North countries between 1994 and 2023, identifying 718 instances of problem-shifting risk across 712 climate policies and measures. These risks span sectors, institutions, and regions, manifesting as cascading sectoral shifts, transboundary displacements from the Global North to the Global South, and temporal shifts that intensify climate burdens for future generations. Communities in developing regions—especially those dependent on vulnerable sectors—face disproportionate impacts, compounding existing vulnerabilities. The findings underscore the urgent need for holistic, Earth-system-based approaches to climate action that account for system-wide human-environment interactions, minimize unintended consequences, and prevent further problem-shifting. A transition towards such integrative strategies is essential to achieving equitable and sustainable outcomes in global climate governance.
