摘要

京津冀地区是我国能源消耗、碳排放的集聚区,研究区域内碳达峰、碳中和的推进举措,对实现高质量的区域协同发展至关重要。本文构建了考虑京津冀地区特征的长期能源替代规划系统模型(LEAP-BTH),设置了基准情景、低碳情景、协同情景等主要情景以及8个子情景,完成了2021—2060年京津冀地区相应发展路径的预测分析。结果表明:在基准情景下,京津冀地区能源需求将持续增长,2060年北京市、天津市、河北省的碳排放量分别下降为2020年的41%、40%、53%,实现碳中和目标面临较大挑战;在低碳情景下,2060 年北京市、天津市、河北省的碳排放量分别下降为 2020 年的 20%、26%、46%,相比碳中和目标仍有一定差距;在协同情景下,2060年北京市、天津市、河北省的碳排放量分别下降为2020年的13%、15%、21%,能够基本实现碳中和目标。研究建议,京津冀三省市需针对各自的重点减排部门和路径,提出更明确、更严格的应对措施,如北京市重点推动交通、建筑部门的低碳转型,天津市、河北省着力开展可再生能源替代与工业绿色升级;优化顶层设计,挖掘区域内工业、能源、交通等部门的协同发展潜力,重点推动产业协同升级和能源协同发展,据此支撑京津冀地区的“双碳”工作和高质量发展。
