摘要

通过对江苏省未来能源需求和碳排放情景的深入分析,制定达到碳达峰和碳中和目标的战略.采用LEAP模型对2021~2060年不同情景下的能源需求和碳排放进行预测.研究发现,在基准情景下,江苏省重点行业的能源需求呈高速增长,2021~2060年能源消费量增加2.35倍,年均增速为3.46%.而在政策执行、可持续发展和创新推进情景下,能源消费总量显著降低,分别为45.98%、58.96%和86.13%,展现出了不同程度的节能潜力.对碳排放的预测显示,在基准情景下,碳排放总量呈持续增长趋势,达到2060年的5.99亿t,年均增速为4.47%.而在3种情景下,碳排放量显著降低,表现为峰值达到2025年或2030年,并逐步下降.具体来看,工业部门逐年降低,交通运输部门呈增长趋势,建筑部门相对稳定.总体而言,随着产业结构调整和技术水平提升,江苏省有望实现碳排放的逐步减少,但需关注交通运输部门的碳排放增加趋势.

Abstract

In this study,strategies for meeting the carbon peak and carbon neutral targets are developed through an in-depth analysis of future energy demand and carbon emission scenarios in Jiangsu Province.The LEAP model was used to forecast energy demand and carbon emissions under different scenarios from 2021 to 2060.Under the baseline scenario,the energy demand of key industries in Jiangsu Province showed a high rate of growth,with energy consumption increasing by 2.35 times from 2021 to 2060,with an average annual growth rate of 3.46%.In contrast,under the Policy Implementation,Sustainable Development,and Innovation Promotion scenarios,total energy consumption decreased significantly by 45.98%,58.96%,and 86.13%,respectively,demonstrating varying degrees of energy-saving potential.Projections of carbon emissions showed that the total carbon emissions under the baseline scenario showed a continuous growth trend,reaching 599 million t in 2060,with an average annual growth rate of 4.47%.In contrast,under the Policy Implementation,Sustainable Development,and Innovation Advancement Scenario,carbon emissions were significantly lower,as evidenced by a peak reaching 2025 or 2030 and a gradual decline.The industrial sector decreased year by year,the transportation sector showed an increasing trend,and the construction sector was relatively stable.Overall,with industrial restructuring and technological upgrading,Jiangsu Province is expected to achieve a gradual reduction in carbon emissions,but the increasing trend of carbon emissions from the transportation sector requires further monitoring.
