本研究估算了 1995 年至 2009 年期间与美国、德国和日本的全球汽车和石油最终需求相关的碳足迹，这些国家在 2009 年占全球乘用车保有量的 31%。我开发了一种全面的新方法，以更清楚地阐明汽车全球最终需求的结构变化。根据结果，我讨论了以延长车辆使用寿命为重点的循环战略如何有助于减少每个国家的汽车碳足迹。虽然全球汽车制造的环境负担有所减轻，但列昂提夫的生产结构抵消了碳减排，完全抵消了技术变革降低排放强度的影响。结果表明，通过延长使用寿命来抑制新车需求大大减少了碳足迹，其效果与工业技术变革相似甚至更大。
This study estimates the carbon footprint associated with global final demand for automobiles and petroleum of the U.S.A., Germany, and Japan, which accounted for 31% of the global stock of passenger cars in 2009, during 1995 to 2009. I develop a comprehensive new method to more clearly illuminate the structural change in automobiles’ global final demand. Based on the results, I discuss how a circular strategy with a focus on vehicle lifetime extension contributes to the automobile carbon footprint in each country. While the environmental burden from automobile manufacturing has decreased globally, the Leontief production structure countered carbon reduction and completely canceled out the effects of technological changes to reduce emission intensities. The results showed that suppressing demand for new cars through lifetime extensions greatly reduced the carbon footprint, in a similar or even greater way than that from changes in industrial technology.
