中国生活能源消费的典型污染物排放及驱动因素研究
Emissions and driving forces of primary air pollutants from residential energy consumption in China
摘要
Abstract
Residential energy consumption is holding an increasingly clear strategic position in China's carbon reduction roadmap.However,comprehensive evaluation and systematic solutions for household sector as an important grasp on improving air quality and human health are still lacking.This paper established urban and rural residential emission inventories for three critical air pollutants (PM2.5,SO2and NOx) in forming haze based on data during 1992-2012.And then it analyzed driving factors for total emission dynamics on country level and per capita emission variations on provincial level respectively through LMDI model decomposition.In this way,negative influences of residential energy consumption on air quality wered etected in terms of household,social and technological characteristics.The result showed that first,the PM2.5 emission was reduced by limited amount during research period,and SO2 and NOx emission were increased by 18.5％ and 140.2％ respectively.Per capita emission of urban residents showed evident reduction,and per capita emission of rural residents was still 1.2-8.2 times of urban emission,leading to considerable exposure risk.Second,high emission intensity areas were mainly located in North and Northeast China.Some provinces showed relatively greater urban-rural discrepancies.For instance,rural emission levels of Beijing,Sichuan,Chongqing,Jiangsu and Fujian were much higher than emissions of their urban residents,while the reverse was true for Xinjiang and Heilongjiang for SO2 and NOx emissions.Third,the most dominant positive and negative factors in driving residential pollutions are household income and average energy price,while the effect of population on emission promotion is weakening,and the reduction effects of urbanization and emission factor are becoming more obvious.Besides,it is estimated that price elasticity of urban emission is greater compared to rural emission,while the latter is more sensitive to income variation.Fourth,in order to improve residential emissions reduction of multiple pollutants for both urban and rural households,it is necessary to take regional differences of energy use and emission into account.Based on contributions of main factors to geographical emission difference,urban and rural parts of 30 provinces were divided into 6 categories respectively,which help to form targeted and effective pollution control policies on household perspective in terms of energy structure and price optimization,energy use efficiency and living standard improvement.关键词
