简介:文章采用IPCC和中国《省级温室气体编制指南》推荐的方法对南宁1990—2012年的碳足迹进行了动态分析。研究发现,1990—2012年南宁的碳足迹处于较低水平,但波动上升,增幅为441.0%,年均增幅为20.08%。碳足迹构成上,各部门所占比重由大到小依次是农业部门(60.16%)〉能源部门(30.63%)〉水泥工业部门(12.76%)〉废物处理部门(3.32%),且都大于植被固碳(-6.87%)。由此可见南宁碳足迹主要是由农业生产和化石能源燃烧引起。人均和单位面积碳足迹增幅分别为323.51%和441.82%;万元GDP碳足迹降低了41.0%;能源强度波动下降。温室气体排放指数从0.04波动增加到0.20,1990年排放等级为很低(Ⅰb),1991—2011年为较低(Ⅰc),2012年为中下(Ⅱa)。
