摘要
开展城市道路碳排放测算与分析是服务"双碳"目标、推进交通可持续发展的关键举措.依托"重庆市广阳大道生态修复及品质提升"项目,基于全生命周期评价方法构建城市道路建设阶段的碳排放测算模型,依据模型的计算结果对新建城市道路碳排放关键输入参数进行敏感性分析.从建设材料、施工机械燃料及电力等角度识别碳排放量的主要影响因素,为碳减排策略的提出提供理论技术支撑,有助于实现道路建设从设计到施工全过程的绿色发展.
Abstract
The calculation and analysis of urban road carbon emissions is a key measure to serve the"double carbon"goal and promote the sustainable development of transportation.Based on the Ecological Restoration and Quality Improvement Project of Guangyang Avenue in Chongqing,a carbon emission calculation model of urban road in construction stage is built based on the full life circle evaluation method.According to the calculation result of the model,the sensitivity analysis of key input parameters of carbon emission of newly built urban roads is carried out.The main influencing factors of carbon emission are identified from the perspectives of construction materials,construction machinery fuel and electricity,which provide the theoretical and technical support for the proposal of carbon emission reduction strategies and contributed to the green development of road construction from the design and construction process.
