Research On Influence Of Carbon Emissions From Energy Consumption In Yangtze River Delta Based On LMDI

Global climate warming is the most significant and serious environmentalproblem which humanity has ever faced. Many studies have proved that the climatechange caused by greenhouse gas emissions from human activities.Thereforeinhibiting the growth rate of carbon dioxide and other greenhouse gas emissionshas become the inescapable responsibility of all countries in the world formitigating climate change. The Yangtze River Delta region is one of the mosteconomically developed regions in China. More attention on the situation of carbonemissions in the Yangtze River Delta has been given, whether it is in respond toclimate warming, or to achieve the sustainable development of the Yangtze RiverDelta region. Yangtze River Delta region must take the low-carbon way of energysaving and emissions reduction.Firstly, this paper makes a detailed analysis about overall characteristics of theYangtze River Delta’s economic, energy consumption and carbon emissions. Theresults show that energy consumption and carbon emissions of this area are highfrom1995to2010, which are being increased year by year. The intensities of bothenergy consumption and carbon emissions have tended to decline, but the per capitaenergy consumption and per capita carbon emissions have tended to rise.Secondly, set up an incremental factor decomposition model of carbonemissions by LMDI method. The model was adopted to analyze the driving effectof economic scales, population sizes, energy intensity and energy structures oncarbon emissions increment in Yangtze River Delta from1995to2010. Empiricalresults demonstrated that the economic scales effect, whose contribution ratioreached144.19%, played a dominant role in increases in carbon emission.Theeffect of energy intensity, population sizes and energy structures were-60.97%,19.25%and-2.47%respectively. The results show that the economic scales werefound to be the largest driving effect of carbon emissions increment. Thepopulation sizes played a negligible role in carbon emissions. The energy intensitywas considered to be an important constraint factor for carbon emissions. Theenergy structure restraining to carbon emissions was unapparent.Finally, according to the above results of the research, the paper proposedsome policy measures and suggestions of carbon reduction in the Yangtze River Delta region.
