能源富集区贸易隐含碳及隐含SO2排放转移——以山西省为例

通过量化地区间碳排放和SO₂排放转移特征,可以较好地了解地区间的碳排放和SO₂排放的来源与去向,从而合理地制定各地区的减排与治理方案。采用多区域投入产出模型,计算2007年和2012年山西省输出和输入的隐含碳和隐含SO₂排放情况。结果表明：山西省为隐含碳和隐含SO₂排放输出区,输出的地区主要是江苏、河北、浙江和山东等地,输入的地区主要是河北、山东、内蒙古和河南等地。山西省向其他地区转移的隐含碳和隐含SO₂排放主要汇聚于金属冶炼及制品业、建筑业和化学工业等。其他地区向山西省转移的隐含碳和隐含SO₂排放主要集中于建筑业、采选业、金属冶炼及制品业等。基于上述研究结论,提出了一些关键性整改建议与措施。

Study on trade embodied carbon and embodied SO2 emission transfer in energy enrichment areas:A case study of Shanxi province

The source and direction of the embodied carbon emissions and the embodied SO₂ emissions between regions can be better understood by quantifying their transfer characteristics between regions, so as to make up the emission reduction and control plan for each region in a rational way. In this paper, a multi-regional input-output model is used to calculate the embodied carbon and SO₂ emissions from Shanxi province in 2007 and 2012. The results show that Shanxi was the export area of the embodied carbon and the embodied SO₂. The export areas were mainly located in Jiangsu, Hebei, Zhejiang, Shandong, and the input areas were mainly found in Hebei, Shandong, Inner Mongolia and Henan. The embodied carbon and the embodied SO₂ emissions transferred from Shanxi to other regions were mainly concentrated in the metal smelting and products industry, construction industry and chemical industry. The embodied carbon and the embodied SO₂ emissions transferred from other regions to Shanxi were mainly concentrated in the construction industry, mining and separation industry, metal smelting and products industry. Based on the above conclusions, some key suggestions and measures are put forward.
