摘　　要：以人均历史累计排放为基础,借用了收入分配公平的研究思路,以洛仑兹曲线和基尼系数为指标,尝试以一个综合性的指标测度排放空间中的分配公平问题。对碳基尼系数的分析表明,目前70%的排放空间被用于不公平分配,其分配差异同目前收入差异最悬殊的国家在同一水平上,解决碳公平问题迫在眉睫。基于人均累计排放的碳基尼系数可以用以度量碳排放空间的不平等,并为国际社会对碳公平的讨论提供一个量化的指标。This paper uses Lorenz Curve and Gini Index with adjustment to per capita historical cumulative emission and constructs Carbon Gini Index to measure inequality in climate change area.The analysis using Carbon Gini Index shows that 70% of carbon space in the atmosphere has been used for unequal distribution,which is almost the same as that of income in the country with the biggest gap between rich and poor in the world.The carbon equity should be an urgency and a priority in the climate agenda.Carbon Gini Index established in this paper can be used to measure inequality in distribution of carbon space and provide a quantified indicator for measurement of carbon equity among different proposals.
