摘要
为了厘清生命周期评价(LCA)方法在道路基础设施碳排放核算方法以及现有减排技术的发展状况,通过定量挖掘现有文献方法,明确了当前道路交通系统碳排放的研究热点;总结了道路基础设施LCA碳排放核算分析框架,对比分析了不同类型LCA的碳排放核算方法和评估工具的特点;按照原材料获取、施工建造、运营使用、养护维修、报废回收5个生命阶段,分别总结了道路基础设施各阶段的碳排放贡献水平、影响因素与主要的减排措施。研究结果表明:在道路基础设施全生命周期中,材料生产和使用阶段对碳排放量的贡献最大;材料生产、建设、使用、维护等阶段碳排放主要影响因素分别源于材料及其生产加工方案、路面类型与结构、施工机械、车辆排放、养护技术及其导致的交通延误等;相应地,优化材料生产过程、使用清洁生产技术和回收材料,缩短材料运输距离、选用环保修复技术等方法则是道路基础设施全生命周期中主要的减排措施;未来道路基础设施LCA可开展建立现场核算数据库、构建标准化的碳核算体系框架、制定标准化的评估方法等工作,为实现道路基础设施的低碳可持续发展提供技术支持。
To clarify the application of life cycle assessment(LCA)in carbon emission accounting methods for road infrastructure and the development status of existing emission reduction technologies,the current research hotspots on carbon emissions from road transportation systems were identified through quantitative analysis of existing literature.The carbon emission accounting analysis framework for road infrastructure LCA was summarized,and the characteristics of carbon emission accounting methods and evaluation tools for different types of LCA were comparatively analyzed.According to the five life stages,i.e.,raw material acquisition,construction,operation and use,maintenance and repair,and scrapping and recycling,the carbon emission contribution levels,influencing factors,and main emission reduction measures of road infrastructure at each stage were summarized respectively.The research results show that during the entire life cycle of road infrastructure,the material production and use stages contribute the most to carbon emissions.The main factors affecting carbon emissions during the stages of material production,construction,use,and maintenance are derived from materials and their production and processing plans,road surface types and structures,construction machinery,vehicle emissions,maintenance techniques,and the resulting traffic delays.Correspondingly,the primary emission reduction measures throughout the entire life cycle of road infrastructure include optimizing material production processes,using clean production technologies and recycling materials,shortening material transportation distances,and selecting environmentally friendly restoration technologies.Some future studies,such as establishing on-site accounting databases,building standardized carbon accounting system frameworks,and developing standardized evaluation methods,could be carried out for road infrastructure LCA,to provide technical support for the low-carbon and sustainable development of road infrastructure.
