市政道路碳排放计算及分析

Calculation and Analysis of Carbon Emissions from Urban Roads

摘要:

首先，基于城市道路全生命周期的评价方法，提出了市政道路及配套设施的碳排放计算原则和思路，构建了市政道路及配套工程“建造阶段、运行阶段和拆除阶段”3个阶段的碳排放计算模型；然后，通过分类统计不同阶段的能耗和碳排放因子，定量分析了市政道路全生命周期的碳排放量以及碳汇量；最后，通过实际案例，论述了所提出的碳排放计算模型在碳达峰、碳中和分析中的基本步骤以及所需要收集的资料，以期为后续市政道路及其他市政基础设施建设项目参与碳排放交易、碳足迹等工作提供技术参考。

Abstract:

Based on the evaluation method of the full life cycle of urban roads, the principles and ideas for calculating the carbon emissions of urban roads and supporting facilities are proposed. The calculation model of carbon emission of urban roads and supporting engineering in three stages of "construction stage, operation stage and demolition stage is built. Through the classified statistic of the energy consumption and carbon emission factors in the different stages, the carbon emission and carbon sink of the full life cycle of urban roads are quantitatively analyzed. Through the practical examples, the basic steps of the proposed carbon emission calculation model in carbon peaking and carbon neutrality analysis and the data needed to be collected are discussed in order to provide the technical reference for the subsequent urban roads and other municipal infrastructure construction projects to participate in carbon emission trading, carbon footprint and other works.
