The present study investigates the driving factors leading energy and carbon intensity of the economies of the USA and Germany, being two economies with different structures and dependencies on energy while they are among the world's economic and geopolitical leading players. Both decoupling and decomposition analysis (overall and sectoral) are applied to identify and rank factors defining carbon and energy intensity during the period from 2000 to 2017, with the so-called financial crisis being within this period. The decoupling analysis denotes that these advanced economies have reached a weak decoupling status, while decomposition analysis confirms the leading role of energy intensity in CO emissions, followed by the income (positive contribution) and the energy mix emerge as important factors with population (positive contribution) trend to be an additional factor only in the USA.
本研究考察了导致美国和德国经济的能源和碳强度的驱动因素,这两个经济体的结构和对能源的依赖程度不同,而它们是世界经济和地缘政治的主要参与者之一。在 2000 年至 2017 年期间(包括所谓的金融危机),应用脱钩和分解分析(总体和部门)来识别和排名定义碳和能源强度的因素。脱钩分析表明,这些发达经济体已经达到了弱脱钩状态,而分解分析则证实了能源强度在 CO 排放中的主导作用,其次是收入(正向贡献)和能源组合,人口趋势也是一个重要因素(正向贡献),仅在美国,人口趋势是一个额外因素。
