Energy-related CO₂ emissions embodied in international trade have been widely studied at the national level in recent years. The embodiment estimates help to explain the 鈥渨eak carbon leakage鈥?between industrial and developing countries and to reveal the so-called 鈥渃onsumption-based鈥?emissions (or carbon footprint). These findings have implications on national climate policy and international negotiations. For a large country like China, spatial aggregation issues are important in embodied emission studies. Dividing the country into several regions, previous studies propose the hybrid emissions embodied in trade (HEET) approach for regional emission studies and use step-wise distribution of emissions embodied in trade (SWD-EET) analysis to explain indirect absorption patterns. In this paper, we combine the HEET approach and SWD-EET analysis to conduct a comprehensive study of China鈥檚 regional emission embodiments. We explain how inter-regional trade and international trade affect China鈥檚 regional domestic emissions, and present the resulting regional carbon footprint. Policy implications from the empirical results obtained are discussed.
