Based on the data of industrial carbon emissions in Chang-Zhu-Tan urban agglomerations during 2005 to 2010, simulates and forecasts industrial carbon emissions in Chang-Zhu-Tan urban agglomerations from 2005 to 2030 by grey system theory, and analyzes the industrial carbon emissions under four set scenarios from 2011 to 2030. The results indicate that: if the city group keeps the industrial structure before 2010 and the energy structure maintains unchanged from 2010 to 2030, the industrial carbon emissions will increase at an annual growth rate of 15.99%. On the significant level of 1%, there exists a bidirectional cause-effect relationship between carbon emission, GDP per capita, population, per unit GDP energy intensity and the carbon emission intensity; There is a long-term equilibrium relationship between Chang-Zhu-Tan industrial carbon emission and economic growth-indicated per capita GDP. Under the situation of BAU, energy saving, low-carbon and stressed low-carbon, both the industrial carbon emissions and GDP per capita of Chang-Zhu-Tan urban agglomerations are increasing.
