摘要
基于能源生产和消费不同视角研究碳排放流动特征,明确碳排放责任,对“全国一盘棋”统筹推进减碳起到至关重要作用。该研究以2000-2020年为分析时段,采用碳排放因子法精准核算黄河流域能源生产和消费侧碳排放量;基于能流图和碳流图,定量揭示流域及各省区生产和消费侧的能源-部门-碳之间的关联、能源流动特征、碳排放动态演变等;在此基础上,进一步分析流域内相邻省区碳排放协同特征,阐明流域碳排放差异的主要原因。结果表明:①2000-2020年,黄河流域能源生产侧碳排放8量比消费侧高10%~31%,且碳排放差额逐渐增大,2020年差额达到7.27×10^(8) t,原因在于黄河流域二次能源净调出量逐年增加。②黄河流域9省区碳排放差额呈现3种演变趋势,其中,青海省、四川省、河南省由能源生产侧碳排放量高转变为消费侧高,山东省则呈相反趋势,而流域中部省区生产侧碳排放量一直高于消费侧。③能源生产主导型的内蒙古自治区生产侧碳排放量远高于消费侧,生产侧碳排放中近60%来自火力发电,原因在于能源加工转换中原煤使用量持续增加,且火力发电效率较低。由于电力低碳化程度高,能源消费主导型的四川省工业电力终端消费占比达到24.47%,但相应碳排放仅为9.20%。④黄河流域内相邻省区碳排放协同状态向好发展,2020年呈现“东西良好协调,中部初步协调”的特征。研究显示,黄河流域以能源生产主导型省区为主,明确能源生产侧与消费侧的碳排放责任、制定各省区差异化减碳战略、构建省区间协同减碳机制,有利于支撑流域实现“双碳”目标。
Studying the characteristics of carbon emission from the perspectives of energy production and consumption is essential to clarify carbon emission responsibilities in advancing nationwide carbon reduction efforts.This study first accurately calculated production-based and consumption-based carbon emissions in the Yellow River Basin using carbon emission factor method from 2000 to 2020.Then,a material flow analysis method was used to reveal the existed linkages and trends between energy,industrial sectors,and carbon emissions.A coupled coordination model was constructed to further explore the collaborative features of carbon emissions among adjacent provinces and to elucidate the main reasons of carbon emissions across the provinces within the basin.The findings indicate that:(1)Throughout the study period,the production-based carbon emissions in the basin were higher than its consumption-based carbon emissions;and the margins were progressively expanding from 10%to 31%,reaching 727 million tons in 2020 due to the basin’s annual increase in the net transfer of secondary energy outflows.(2)Three distinct trends can be seen in the carbon emission margins of the nine provinces in the basin:Qinghai,Sichuan,and Henan showed a shift from higher production-based carbon emissions to higher consumption-based carbon emissions,while Shandong displayed the opposite trend;central provinces continued to exhibit higher production-based carbon emissions.(3)In production-oriented province,such as Inner Mongolia,nearly 60%of production-based carbon emissions come from thermal power generation,mainly due to the continuous increase in coal consumption during the secondary energy conversion process coupled with relatively low efficiency of thermal power generation.In contrary,in Sichuan,a consumption-oriented province,the industrial sector′s electricity consumption accounted for 24.47%of total energy consumption,yet its carbon emissions were only 9.20%.(4)The collaborative state of carbon emissions among adjacent provinces in the
