The growth of global carbon emissions is largely driven by coal-burning in China. China has consumed approximately half of global coal; as such, limiting its coal demand is important for curbing carbon emissions in the country and around the world. Developing effective approaches to limit China's coal demand requires comprehensively understanding the trajectory and drivers shaping its coal footprint in the globalized world. Past studies have investigated production-based coal consumption within China's sovereign territory boundary, but have not addressed consumption-based coal consumption and the globalization background. To fill this research gap, this study conducted a multi-regional input-output analysis - structural decomposition analysis to analyze China's coal footprint in a globalized world. The results show a continued rise in the influence of globalization on China's coal consumption, despite the 1997 Asian financial crisis and 2008-09 global economic crisis lowering of global trade. The percentage of other countries' coal demand on China's production-based coal footprint increased from 20% in 1995 to nearly 30% in 2011, through a global transfer of virtual coal through trade. Virtual coal refers to the coal consumed to support production activities. Meanwhile, the impact of other countries' coal supply on China's consumption-based coal footprint increased from less than 2% in 1995 to more than 4% in 2011. However, the decomposition results showed that domestic demand was the leading contributor to Chinese production-based and consumption-based coal footprint. This was offset by the domestic coal intensity effect. To cut China's coal, strategies to cap its total coal consumption should be considered in a globalized world. Improving energy intensity is an effective approach for the country; China should be leveraging the globalized world, rather than serving as the world's factory through high coal consumption and exports.
全球碳排放的增长在很大程度上是由中国的煤炭燃烧驱动的。中国消耗了全球大约一半的煤炭;因此,限制其煤炭需求对于遏制中国乃至全球的碳排放至关重要。为了限制中国的煤炭需求,开发有效的方法需要全面了解塑造中国在全球化世界中煤炭足迹的轨迹和驱动因素。过去的研究调查了中国主权领土范围内的基于生产的煤炭消费,但没有涉及基于消费的煤炭消费和全球化背景。为了填补这一研究空白,本研究进行了多区域投入产出分析——结构分解分析,以分析全球化世界中中国的煤炭足迹。研究结果表明,尽管 1997 年亚洲金融危机和 2008-09 年全球经济危机降低了全球贸易,但全球化对中国煤炭消费的影响仍在继续上升。通过贸易实现的虚拟煤炭在全球范围内的转移,使得其他国家对中国基于生产的煤炭足迹的煤炭需求占比从 1995 年的 20%上升到 2011 年的近 30%。虚拟煤炭是指为支持生产活动而消耗的煤炭。与此同时,其他国家的煤炭供应对中国基于消费的煤炭足迹的影响从 1995 年的不到 2%增加到 2011 年的 4%以上。然而,分解结果表明,国内需求是导致中国基于生产和消费的煤炭足迹的主要因素。这被国内煤炭强度效应所抵消。为了减少中国的煤炭消耗,在全球化的世界中,应该考虑限制其煤炭总消费量的战略。提高能源强度是中国的有效途径;中国应该利用全球化的世界,而不是通过高煤炭消耗和出口来充当世界工厂。
