摘要
在绿色经济发展趋势下,中国政府积极倡议建立"一带一路"绿色发展国际联盟,这离不开对"一带一路"沿线国家温室气体排放特征与减排立场的掌握。构建"一带一路"沿线国家CH4减排潜力指数,梳理1990-2014年"一带一路"沿线国家温室气体排放现状、排放来源,以期为"一带一路"绿色发展联盟相关政策的制定提供参考。结果显示:"一带一路"沿线国家高排放总量与高人均排放量空间分离,形成了"高总量-低人均"和"高人均-低总量"的两类排放特征;除CO2外,"一带一路"沿线国家CH4排放超世界平均水平,CH4减排不容忽视;"一带一路"温室气体排放源存在国家间差异,大多数国家以能源产业部门为主要排放源,但农业部门排放、土地利用变化和森林植被变化也构成了阿富汗、孟加拉国等国家的主要排放源。
Under the trend of green economic development,the Chinese government has actively advocated the establishment of an international alliance along the Belt and Road,which is inseparable from the grasp of the Belt and Road countries on the greenhouse gas emission characteristics and position of emission reduction.The study analyzed herein uses greenhouse gas(CHG) emissions data during the 1990-2014 in the countries along the Belt and Road and carries out a trend analysis of the commitments(NDC) made by individual government in the countries along the Belt and Road to explore the future GHG emission reduction trend.The present situation and sources of greenhouse gas emissions of countries along the Belt and Road from 1990 to 2014 are summarized,so as to provide reference for the formulation of related policies of he Belt and Road green development alliance.The results suggest that countries with high GHG emissions tend to have low per capita emissions,while countries with high per capita emissions have lower total emissions along the Belt and Road,forming "high gross-low per capita"and "high per capita-low aggregate"two types of emission characteristics.The results also show that in addition to CO2,CH4 emission of countries along the Belt and Road exceeds the world average,and CH4 emission reduction cannot be ignored;the Belt and Road greenhouse gas emission sources vary among countries.Most countries take the energy industry sector as the main emission source,but agricultural sector emissions,land use change and forest vegetation change also constitute the main emission sources of Afghanistan,Bangladesh and other countries.
