CHINA is currently the world largest emitter of energy-related carbon dioxide (CO2). Understanding the driving forces governing CO2 emission levels and their evolutions in China can provide useful information for policy makers who aim to reduce green house gas emissions. Because of policy and historical reasons, considerable regional growth and income disparities exist in China. The regional disparities may influence energy use and CO2 emissions. Therefore, this study is to investigate the driving forces governing CO2 emission levels and their evolutions at regional level in China.
