碳减排“时-空-效-益”统筹理论:Ⅱ.空间统筹

The Carbon Mitigation “Time-Space-Efficiency-Benefit”(TSEB)Coordination Theory:II.Space Coordination

《联合国气候变化框架公约》(UNFCCC)倡导缔约方承担“共同但有区别”的减排责任,指出“各缔约方应当在公平的基础上,根据它们共同但有区别的责任和各自的能力,为人类当代和后代的利益保护气候系统。”《联合国气候变化框架公约》体现出应对气候变化两个维度的公平性,即区域公平性和代际公平性。其中,区域公平性一般指国家之间应对气候变化的责任分担问题(如各国的减排目标设定、排放配额分配等)。作为碳减排“时-空-效-益”统筹理论系列论文的组成部分,围绕气候治理中区域公平性与主体间博弈问题,构建了空间统筹方法,应用于全球和国家层面最优减排路径研究,科学回答了各区域主体减排责任分担及局部与整体减排协同关系问题,为统筹局部减排与整体减排提供方法基础。

The United Nations Framework Convention on Climate Change(UNFCCC),adopted in 1992,advocates for Parties to undertake“common but differentiated” responsibilities for emission reductions,emphasizing that “Parties should protect the climate system for the benefit of present and future generations of humankind,on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities.” The Convention reflects two dimensions of equity in addressing climate change:regional equity and intergenerational equity.Among them,regional equity mainly involves the issue of responsibility sharing among countries in addressing climate change.As part of the series of papers on the carbon mitigation “Time-Space-Efficiency-Benefit”(TSEB) coordination theory,this paper focuses on the issues of regional fairness and inter subject game in climate governance.It constructs a spatial coordination method and applies it to the study of the optimal emission reduction path at the global and national levels.It scientifically answers the questions of the sharing of emission reduction responsibilities among regional subjects and the coordination between local and overall emission reduction,providing a methodological basis for coordinating local and overall emission reduction.
