This paper applied the Tapio and LMDI methods based on an extended Kaya identity, to evaluate the decoupling and factors that influenced the relationship between economic growth and CO emissions in Cameroon from 1990 to 2015. The analysis covered the two main sectors of Cameroon's economic activity, and the decoupling indicators were broken down into five factors. The results showed that Cameroon performed weak decoupling throughout this study period. A weak negative decoupling and a strong negative decoupling appeared during the periods 1990-1992 and 1993-1994, whereas a strong decoupling occurred only from 1994 to 1995 and between 2004 and 2006. From a general point of view, we found that demographic change, followed by energy intensity and economic activity, played a negative role in decoupling, while economic structure and emission factors had promoted the development of decoupling. A comparative analysis of the industrial and tertiary sectors revealed that industrial growth determined the degree of decoupling of CO emissions from Cameroon's economic growth. The policy will need to optimize and significantly adjust the energy and industrial structures if Cameroon's 2035 emission reduction targets are to be reached. This requires a change in Cameroon's energy consumption and economic development pathways for optimal outcomes.
本文应用基于扩展凯亚恒等式的 Tapio 和 LMDI 方法，评估了 1990 年至 2015 年喀麦隆经济增长与 CO2 排放之间的脱钩关系及其影响因素。该分析涵盖了喀麦隆经济活动的两个主要部门，脱钩指标被细分为五个因素。结果表明，喀麦隆在整个研究期间表现出弱脱钩。1990-1992 年和 1993-1994 年期间出现了弱负脱钩和强负脱钩，而仅在 1994 年至 1995 年和 2004 年至 2006 年期间出现了强脱钩。从总体上看，我们发现人口变化、其次是能源强度和经济活动对脱钩产生了负面影响，而经济结构和排放因素促进了脱钩的发展。对工业和第三产业的比较分析表明，工业增长决定了喀麦隆经济增长与 CO2 排放脱钩的程度。如果要实现喀麦隆 2035 年的减排目标，政策将需要优化和大幅调整能源和工业结构。这需要改变喀麦隆的能源消费和经济发展路径，以实现最佳效果。
