摘要
水电是清洁、低碳的可再生能源,大力发展水电是应对气候变化不可或缺的重要途径。本研究从温室气体的源汇变化及生命周期的物质和能量输入输出等方面深入分析了水电工程碳足迹的科学内涵。水电工程的碳足迹包含水电站本身碳足迹与服务功能导致的其他碳足迹两大部分,主要包括前期准备阶段、施工建设阶段、运营维护阶段及拆除恢复阶段。研究提出了基于不同方法对水电碳足迹进行核算的技术路径,核算的技术路径通常包括碳足迹核算的准备、建立水电工程碳足迹核算的生命周期清单、碳足迹影响的分析、碳足迹核算结果的解释、碳足迹核算报告编制与评审。水电工程项目碳足迹核算将为支撑水电工程的清洁及优越属性,探索减少水电工程生命周期碳排放的途径提供理论指导,同时为水电行业碳排放管理提供技术支撑。
Hydropower is a clean,low-carbon renewable energy source,developing hydropower is an important way of the fight against climate change.In this study,the scientific connotation of carbon footprint of hydropower projects is analysed from the change of greenhouse gas sources and sinks,and the input and output of matter and energy in the life cycle.The carbon footprint of hydropower project includes the carbon footprint of hydropower station itself and other carbon footprints caused by service functions,including the preliminary preparation stage,construction stage,operation and maintenance stage and demolition and restoration stage.Further,this study puts forward the technical path of accounting for hydro-electric carbon footprint based on different methods.The technical path of accounting usually includes the preparation of carbon footprint accounting,the establishment of the life cycle list of carbon footprint accounting for hydropower engineering,the analysis of carbon footprint impact,the interpretation of carbon footprint accounting results,the preparation and review of carbon footprint accounting report.The carbon footprint accounting of hydropower projects will provide theoretical guidance for supporting the clean and superior attributes of hydropower projects and exploring ways to reduce carbon emissions during the life cycle of hydropower projects.At the same time,it will provide technical support for carbon emission management of hydropower industry.
