摘要
本文基于IPCC排放因子法借助化石能源的碳排放量与水泥生产的碳排放量两部分数据,核算2013—2017年长沙市的碳足迹并分析其动态变化,通过林地、农作物的固碳能力核算长沙市的碳承载力。结果显示,2013—2017年长沙市碳足迹呈下降趋势,碳承载力呈上升趋势,但变化趋势都在逐步放缓。未来较长时期长沙市净碳足迹还会持续下降,但仍处于碳赤字状态。能源消费结构决定了长沙市仅依靠能源利用效率的提高很难达到快速降低碳排放的效果。调整能源结构,低碳新能源的使用,可以快速降低碳排放量。
Based on the data of carbon emissions from fossil energy and cement production by IPCC emission factor method,this paper calculates the carbon footprint of Changsha from 2013 to 2017 and analyzes it’s dynamic changes with the carbon emission data of fossil energy and cement production,and calculates the carbon bearing capacity of Changsha through the carbon sequestration capacity in woodland and crops.The results show that,the carbon footprint of Changsha showed a downward trend,and the carbon bearing capacity showed an upward trendfrom 2013 to 2017,but both trends were gradually slowing down.The net carbon footprint of Changsha will continue to decline in a long time,but it will still be in the state of carbon deficit.The structure of energy consumption determines that it is difficult to reduce carbon emissions quickly by relying on the improvement of energy.Adjusting the energy structure and using low-carbon new energy can quickly reduce carbon emissions.
