The deepening of China’s regional economic integration has posed potential impacts on climate change mitigation. This paper evaluates the impact of Changsha-Zhuzhou-Xiangtan economic integration policy on carbon emissions based on the total industrial output value, analyzes the correlation between carbon emission and total industrial output value of Changsha-Zhuzhou-Xiangtan urban agglomeration from 2000 to 2014, and calculates the carbon dioxide emission per unit of industrial added value. The results show that under the influence of economic integration, the carbon dioxide emission per unit industrial added value of Changsha-Zhuzhou-Xiangtan urban agglomeration decreases significantly, and low-carbon industry gradually occupies a dominant position. The results are helpful for the design of carbon emission reduction path and the formulation of carbon neutralization long-term policy of Changsha-Zhuzhou-Xiangtan urban agglomeration.
