城区与街区尺度碳排放测算方法综述

Review on the Measurement Methods of Carbon Emission on Urban and Block Scale

随着中国2030年“碳达峰”和2060年“碳中和”远景目标的提出,碳排放研究将成为我国未来较长一段时间内的重要课题。城市规划作为实现减排降碳的重点领域,受到社会与学界的广泛关注。为了给规划领域碳减排相关研究提供参考,介绍了国内外城区和街区尺度碳排放测算方法,包括基于活动的碳排放测算技术、基于监测的碳排放测算技术以及其他碳排放测算技术,分析各方法的优劣势、适用尺度与适用对象,并阐述了国内外城区建筑碳排放测算模型在工程中的应用,探讨了现有碳排放测算方法存在的不足,提出未来城区尺度碳排放测算的改进建议,旨在为推进城市绿色低碳发展转型、实现“碳达峰”与“碳中和”目标提供支撑。

With “Dual-Carbon Goals”(realizing carbon peak before 2030 and carbon neutrality before 2060),the study of carbon emissions will become an important topic in China for a long time to come.As a crucial area for reducing carbon emissions,urban planning has received considerable attention from society and academia.This paper aims to provide a reference for carbon emission reduction research in the field of planning.It introduces different carbon emission measurement methods used in urban and block scale,including activity-based,monitoring-based,and other techniques.The paper examines the advantages and disadvantages of each method,as well as their scale of application and target audience.It describes the use of carbon emission measurement models for buildings in urban areas,both domestically and internationally,within the engineering field.Additionally,it discusses the shortcomings of the existing carbon emission measurement methods and suggests improvements that could be made on the urban scale in the future.The objective of this paper is to offer assistance in advancing the transition of urban areas towards environmentally friendly and low-emission development,while also attaining targets pertaining to carbon limitation and carbon neutrality.
