基于二次能源省际调配的中国分省CO2排放量计算

节能减排目标任务的制定需要依据科学合理的CO2排放量测算。现有的IPCC提供的CO2排放量计算方法仅考虑一次能源燃料所产生的CO2,未考虑到二次能源省际调配的情况,不能真实反映各省CO2排放情况。本研究提出了考虑二次能源省际调配情况下CO2排放量的计算方法,并以2009年的数据为例,对各省能源消费CO2排放量进行了计算。考虑二次能源省际调配后,传统的能源大省如内蒙古、山西的CO2排放总量下降,东部沿海省份的CO2排放总量上升。中西部地区的CO2排放强度仍显著高于东部地区。中西部地区存在能源利用效率低、能源加工技术设备落后的情况,导致了西部地区的CO2排放强度偏高。建议中央在实施西部大开发"十二五"规划时,应当加强对中西部地区能源加工行业的投资,改善能源加工技术,改良加工设备,提高能源加工效率,降低CO2排放强度。建议由能源调入省向能源调出省份实施补偿。该部分补偿资金用于调出省的能源产业升级改造,以顺利实现节能减排的目标。

Calculation of Carbon Dioxide Emissions Considering Secondary Energy Deployment Among Provinces in China

Scientific and rational calculation of carbon dioxide emissions provides the base is for setting energy saving and emission reduction targets.The existing IPCC’s method to calculate carbon dioxide emissions only considered primary energy fuels,but did not consider the secondary energy deployment,which did not reflect the true situation of carbon dioxide emissions and Chinese situation.This study provided a new method to calculate carbon dioxide emissions considering secondary energy deployment,and according to this method,carbon dioxide emissions of every province were estimated based on the statistic data in 2009.The results showed that carbon dioxide emissions in traditional energy production provinces,such as Inner Mongolia and Shanxi,decreased,and those in eastern coastal provinces increased after considering the secondary energy deployment.But the CO2 emission intensity in the central and western provinces were significantly higher than those in the eastern coastal provinces.Low energy efficiency,backward energy processing technology and equipment existed in the central and western provinces,which resulted in high intensity of carbon dioxide emissions.Recommendation was made to the central government to enhance investment in energy processing industry in the western provinces to improve energy processing technology,processing equipment to increase energy efficiency and to reduce carbon dioxide emissions.The secondary energy-transferred-inprovinces should provide compensation funds to secondary energy-transferred-out-provinces,and this part of the compensation funds should be used to upgrade energy industry for traditional energy production provinces in order to achieve emissions-reduction targets successfully.
