对世界 33 个国家与能源相关的二氧化碳排放量进行了分解分析。数据涉及 1995 年至 2007 年期间。使用的方法是指数分解分析，可以调查以下因素的贡献： (i) 减排技术、燃料质量和燃料转换的变化； (ii) 能源系统结构和效率的变化； (iii) 一个国家在 GDP（国内生产总值）总量方面的相对排名以及 (iv) 该国特定经济活动总量的变化。 WIOD（世界投入产出数据库）与经济合作与发展组织（OECD）的 GDP 数据一起使用。结果表明，经济增长是能源相关二氧化碳排放增加的主要驱动因素。然而，在印度和中国等快速发展的国家，一个重要的贡献还在于这些经济体在全球经济格局中发挥着越来越大的作用。在本研究中考虑的所有国家中，能源效率的提高是减少二氧化碳排放总量增长的主要因素。 (C) 2016 Elsevier Ltd. 保留所有权利。
A decomposition analysis of energy related CO2 emissions is carried out for 33 world countries. The data pertain to the period 1995-2007. The methodology used is the Index Decomposition Analysis that allows to investigate the contribution of the following factors: (i) changes in abatement technologies, fuel quality and fuel switching; (ii) changes in the structure and efficiency of the energy system; (iii) relative ranking of a country in terms of the total GDP (Gross Domestic Product) generation and (iv) changes of the country specific total economic activity. The WIOD (World Input Output Database) has been used together with Organization for the Economic Co-operation and Development (OECD) data on GDP. Results show that economic growth has been the main driving factor of energy related CO2 emissions increase. However, in fast developing countries like India and China, an important contribution has also been the increasing role that these economies are playing in the global economic panorama. Improvements on energy efficiency have been the main element contributing to reduce the overall CO2 emission increase in all the countries considered in this study. (C) 2016 Elsevier Ltd.
