本研究分析了1980-2005年期间影响选定亚洲国家运输部门二氧化碳（CO2）排放量增长的潜在因素，将年排放量增长分解为代表燃料结构、模式转换、人均国内生产总值（GDP）和人口变化的组成部分，以及排放系数和运输能源强度的变化。我们发现，人均GDP，人口增长和交通能源强度的变化是主要因素驱动交通部门的CO2排放量增长的国家考虑。中国、印度、印度尼西亚、大韩民国、马来西亚、巴基斯坦、斯里兰卡和泰国的交通运输部门二氧化碳排放量呈上升趋势，是人均收入和人口增长造成的;蒙古的交通运输能源密集度下降，也是二氧化碳排放量下降的原因。人均GDP，人口和交通能源强度的影响都被认为是孟加拉国，菲律宾和越南交通部门二氧化碳排放量增长的原因。该研究还审查了政府限制二氧化碳排放增长的现有政策，如财政工具、燃料经济性标准和鼓励转向排放密集度较低的燃料和运输模式的政策。
This study analyze the potential factors influencing the growth of transport sector carbon dioxide (CO2) emissions in selected Asian countries during the 1980–2005 period by decomposing annual emissions growth into components representing changes in fuel mix, modal shift, per capita gross domestic product (GDP) and population, as well as changes in emission coefficients and transportation energy intensity. We find that changes in per capita GDP, population growth and transportation energy intensity are the main factors driving transport sector CO2emission growth in the countries considered. While growth in per capita income and population are responsible for the increasing trend of transport sector CO2emissions in China, India, Indonesia, Republic of Korea, Malaysia, Pakistan, Sri Lanka and Thailand; the decline of transportation energy intensity is driving CO2emissions down in Mongolia. Per capita GDP, population and transportation energy intensity effects are all found responsible for transport sector CO2emissions growth in Bangladesh, the Philippines and Vietnam. The study also reviews existing government policies to limit CO2emissions growth, such as fiscal instruments, fuel economy standards and policies to encourage switching to less emission intensive fuels and transportation modes.
