节水过程碳排放行为及其效益评估方法研究

Research on Carbon Emission Behavior in Water Saving Process and its Benefit Evaluation Method

我国水资源短缺形势严峻,节水工作迫在眉睫,然而节水行为往往会造成用水单位能耗增加,从而引起碳排放量变化。为评估节水过程的碳排放行为,推动节水减碳协同工作,本研究将水资源作为一种产品,以产品碳足迹计算方法为基础,研究形成了水资源节约过程碳排放行为和节水减碳协同效益评估方法,并以居家生活和造纸工业为典型场景,介绍了评估方法的应用情况。通过计算节水过程的碳排放行为,可以丰富节水工作的评价方法,更好地阐述节水减碳协同工作的意义,进而指导节水技术和模式的优化改进。

The situation of water resource shortage in China is severe,and water-saving work is imminent.However,water-saving behavior often leads to an increase in energy consumption per unit of water consumption,resulting in changes in carbon emissions.In order to evaluate the carbon emission behavior of water saving process and promote the collaborative work of water saving and carbon reduction,this paper studied water resources as a product.Based on the product carbon footprint calculation method,this paper formed the carbon emission behavior calculation method and water saving and carbon reduction collaborative benefit evaluation method for water resource saving processes.Taking daily life and paper industry as typical scenarios,it introduced the application of the two methods.By calculating the carbon emission behavior of water saving processes,it could enrich the evaluation methods of water saving work,better explain the significance of water saving and carbon reduction collaborative work,and guide the optimization and improvement of water saving technologies and models.
