摘　　要：《中共中央国务院关于深入打好污染防治攻坚战的意见》中明确提出“将温室气体管控纳入环评管理”,温室气体管控纳入环评已成为深入推进碳达峰行动的重要举措。产业园区是控制污染物和温室气体排放增量的重要载体,是推进减污降碳源头防控的重要抓手。该研究重点围绕协同减污降碳优化规划方案这一关键问题,探索产业园区规划环评中开展温室气体评价的技术方法,并以某石化园区为例开展了实践探索。为了在环评中科学、合理地分析和评价温室气体减排潜力,从两方面探索评价技术方法:一是温室气体与大气耦合评价方法,开展温室气体评价重点排放设施能效分析,结合大气评价中空气质量目标改善要求和初步模拟预测结果,联合提出淘汰高耗低效热源设施、分阶段推进清洁能源替代的规划调整建议;二是研究创新温室气体评价和循环经济分析紧密结合的环评方法,遵循化工园区协同、合作、共享的一体化设计理念和循环经济理念,以资源循环降碳、能效提升降碳为目标,充分发挥化工园区碳固定、碳消纳的天然优势,促进园区内产业链协同。实证研究表明:①通过全面识别园区减污和降碳的关键环节,以“提效-控煤”为主线,温室气体评价与大气评价联合提出热源点整合方案;聚焦园区CO_(2)资源化利用、能源梯级利用,推动两家企业6套装置实施CO_(2)回收,并实施聚碳酸酯、碳酸乙烯酯等CO_(2)产业链利用项目,将零散企业余热资源统一纳网,实现余热余压利用,很好地验证了前述技术方法的可行性,以及温室气体评价对能源规划方案和产业循环经济方案的优化调整作用。②基于现行产业园区环评的评价技术流程,采用全过程纳入模式,提出了温室气体全过程评价技术框架,即现状评价“挖潜力”、规划分析“融理念”、影响识别“定目标”、影响评The Central Committee of the Communist Party of China and the State Council issued the Opinions on Deepening the Battle Against Pollution Prevention and Control.The document clearly states that Greenhouse Gases(GHGs)control should be integrated into the Environmental Impact Assessment(EIA)management process.The notice pointed out that incorporating GHGs control into EIA has become an important initiative to further promote the carbon peaking action.Industrial parks are important carriers for controlling incremental emissions of pollutants and GHGs and promoting reduction of pollution and carbon at source.The key question of the research is to optimize planning options for reducing pollution and carbon emissions in a synergistic manner.Taking a petrochemical park as an example,the technical methods of GHGs assessment during the Planning Environmental Impact Assessments(PEIAs)of industrial parks are discussed.As part of the scientific and rational analysis and evaluation of GHGs emissions reduction potentials in EIAs,this study explores two technical approaches and their roles of GHGs evaluation on planning optimization and adjustment.First,a comprehensive assessment method for GHGs emissions and the atmosphere is proposed,and energy efficiency analysis of key emission facilities for GHGs assessment is carried out to combine the requirements of air quality improvement target in atmospheric assessment with the preliminary simulation results.The joint proposal recommends changes to the planning system to phase out inefficient and energyintensive heat source facilities,and replace them with clean energy in stages.Secondly,study and innovate the PEIA method that closely combines GHGs assessment and circular economy analysis,follow the integrated design concept of chemical industry parks of collaboration,cooperation,and sharing,promote a circular economy to reduce carbon emissions through resource reuse and improved energy efficiency.Making full use of the natural advantages of carbon sequestration and carbon offset in
