居民最终需求已成为我国CO2排放量增长的重要原因。为了测算我国居民因最终需求而直接和间接排放的CO2,本文以1992-2007年价值型投入产出表为基础,结合能源消费实物量数据,编制出混合单位的能源投入产出表,从而得到居民CO2间接排放量占... 居民最终需求已成为我国CO2排放量增长的重要原因。为了测算我国居民因最终需求而直接和间接排放的CO2,本文以1992-2007年价值型投入产出表为基础,结合能源消费实物量数据,编制出混合单位的能源投入产出表,从而得到居民CO2间接排放量占居民碳排总量70%以上且呈上升趋势的结论。在能源投入产出表的基础上,通过结构分解模型,对居民最终需求及相关经济活动引致的CO2间接排放量进行分解分析,结果表明:居民最终需求总量、城乡消费比例及居民消费结构三个方面的变化是促进CO2间接排放量增加的因素,以能源消耗系数下降为特征的生产技术的进步是促使CO2间接排放量减少的主要因素。 展开更多

This study estimates direct radiative forcing by tropospheric ozone and all aerosols between the years 1850 and 2000, using the new IPCC AR5 (the Intergovernmental Panel on Climate Change Fifth Assessment Report) emissions inventories and a fully coupled chemistry-aerosol general circulation model. As compared to the previous Global Emissions Inventory Activity (GEIA) data, that have been commonly used for forcing estimates since 1990, the IPCC AR5 emissions inventories report lower anthropogenic emissions of organic carbon and black carbon aerosols and higher sulfur and NOx emissions. The simulated global and annual mean burdens of sulfate, nitrate, black carbon (BC), primary organic aerosol (POA), secondary organic aerosol (SOA), and ozone were 0.79, 0.35, 0.05, 0.49, 0.34, and 269 Tg, respectively, in the year 1850, and 1.90, 0.90, 0.11, 0.71, 0.32, and 377 Tg, respectively, in the year 2000. The estimated annual mean top of the atmosphere (TOA) direct radiative forcing of all anthropogenic aerosols based on the AR5 emissions inventories is -0.60 W m^-2 on a global mean basis from 1850 to 2000. However, this is -2.40 W m-2 when forcing values are averaged over eastern China (18-45°N and 95-125°E). The value for tropospheric ozone is 0.17 W m^-1 on a global mean basis and 0.24 W m^-2 over eastern China. Forcing values indicate that the climatic effect of aerosols over eastern China is much more significant than the globally averaged effect. 展开更多

As a consequence, million hectares of land exchanged hands. The ways the transfers happened combined with their geographic concentration in Sub-Saharian Africa, have earned the phenomenon the name of "land grab". The agricultural sector considered a "sunset industry" when commodities prices were declining, is now attractive to financial investors. These foreign investments may be good as they may improve agricultural productivity or instead bad as they may benefit only financial investors. Some results in terms of environmental and local communities' worsening conditions have already emerged. This paper aims to investigate what drives the big size transfers of land, to empirically estimate their effects in terms of local employment and to assess the environmental effects produced by the rapid transformation in the use of vast amount of land in terms of CO2 emissions. It is also proposed to use the estimation in terms of local employment impact as a way of distinguishing between foreign direct investment and land grabbing. 展开更多

The output as well as carbon dioxide emissions of tertiary industry have increased continuously in Beijing. Therefore, the tertiary industry has become a new ifeld that needs to be explored for energy saving and emission reduction. This paper calculates the direct and indirect carbon dioxide emissions of tertiary industry in Beijing from 2005 to 2012 using the input-output analysis method. The results indicate that both the direct and indirect carbon dioxide emissions increased continuously and the latter grew more quickly than the former. The growth of the direct and indirect carbon dioxide emissions of tertiary industry was decomposed, which showed that four factors inlfuence the growth of carbon emission of the tertiary industry, including the changes of industrial scale, industrial structure, energy consumption intensity and carbon coefifcient. The results show that the industrial scale advancement and the direct energy carbon coefifcient change promote the increase of direct carbon dioxide emissions, while the shift of industrial structure and the change of direct energy consumption intensity have the restrain on it. The industrial scale enlargement, industrial structure shift and the indirect energy carbon emission coefifcient change promote the growth of indirect carbon dioxide emissions, while the indirect energy consumption intensity change has a restrain. 展开更多

This paper aims to explore the determinants of C〇2 emissions in Laos by accounting for the significant role played by foreign direct investment(FDI)in influencing C 02 emissions during the period 1990-2017.We apply a Johansen co-integration testing approach to investigate the presence of co-integration,and the empirical findings underscore the presence of a long-run co-integration relationship between CO2 emissions,FDI,per capita GDP,and industrial structure.We also employ an error-correcting model to examine the short-term dynamic effect of FDI on CO2 emissions.The empirical results show that FDI has a significant short-term dynamic effect on changes in CO2 emissions,indicating that the relationship between FDI and CO2 emissions is an inverted U-shaped curve.This is a validation of the EKC.Changes of FDI,per capita GDP,and industrial structure increase CO2 emissions.Based on the analysis results,this paper puts forward policy suggestions emphasizing the need for both Laotian policymakers and Chinese investors to improve eco-environmental quality. 展开更多
