Decoupling the growing imbalance from economic growthneeds a stringent and coordinated package of sustainable policies. Previously, enhancing efficiency and vegeta-tion carbon sequestration were dominant drivers to decouple. However, the role and magnitude of restructuringsin the energy sector and economy in decoupling were underestimated. In this context, China’s 30 provinces wereselected as study areas. By employing a carbon footprint pressure (CFP) indicator to represent the imbalance, awidely decoupling method was adopted to describe the decoupling state and trend of CFP and economic growth.An extended IPAT equation and the Logarithmic Mean Divisia Index method were further used to reveal the roleand magnitude of drivers on decoupling. The findings revealed that the CFP climbed significantly in 26 provincesbetween 2006 and 2015. We discovered that 22 provinces were working toward absolute decoupling, with 15provinces achieving it during the 12-th Five-Year Plan. Our analysis revealed that improving energy efficiencywas the primary driver of absolute decoupling, while substituting natural gas and oil for coal, reducing industryshare, and enhancing carbon sequestration accelerated absolute decoupling. Considering the limited future roleof improving energy efficiency and vegetation carbon sequestration, there is an urgent need to optimize andupgrade the structures of the energy sector and economy to mitigate the future climate risk.展开更多
