Abstract

Current flood risk management projects have been criticized for their high carbon emissions, raising the need for carbon emission reduction and carbon absorption efforts to mitigate environmental impacts and achieve carbon neutrality goals. The research develops a comprehensive green disaster risk management toolkit to calculate the carbon emissions and absorption quantitatively based on the unit volume of materials and processes employed in a flood risk management project. As a result of applying the developed toolkit to a about 22,300 small stream restoration projects in Korea, the total carbon emissions were estimated to be 1,158,840.7 tons of CO2, of which 89.4% of the total carbon emissions originated from concrete-related construction activities, such as cement and ready-mixed concrete pouring. As a result of evaluating the nationwide carbon absorption results of all small stream restoration projects, total absorption by 2030 is expected to be 3.0 to 10.2 times higher than carbon emissions. The comprehensive toolkits are expected to support the selection of customized processes, materials, and methods by providing a systematic approach to calculate and minimize carbon emissions, ultimately contributing to the achievement of carbon neutrality goals in flood risk management projects.
开发绿色灾害管理工具包,在洪水风险管理中实现碳中和目标
目前的洪水风险管理项目因碳排放量高而饱受诟病,因此需要努力减少碳排放和吸收碳,以减轻对环境的影响,实现碳中和目标。本研究开发了一套全面的绿色灾害风险管理工具包,可根据洪水风险管理项目中使用的材料和工艺的单位体积,定量计算碳排放量和碳吸收量。将开发的工具包应用于韩国约 22,300 个小型溪流修复项目后,碳排放总量估计为 1,158,840.7 吨二氧化碳,其中 89.4% 的碳排放源于与混凝土相关的施工活动,如水泥和预拌混凝土浇筑。通过评估全国范围内所有小溪流修复项目的碳吸收结果,预计到 2030 年,总吸收量将是碳排放量的 3.0 到 10.2 倍。综合工具包提供了计算和最大限度减少碳排放的系统方法,预计将支持定制工艺、材料和方法的选择,最终有助于实现洪水风险管理项目的碳中和目标。

期刊介绍: Journal of Hydrology publishes original research papers and comprehensive reviews in all the subfields of the hydrological sciences, including water based management and policy issues that impact on economics and society. These comprise, but are not limited to the physical, chemical, biogeochemical, stochastic and systems aspects of surface and groundwater hydrology, hydrometeorology, hydrogeology and hydrogeophysics. Relevant topics incorporating the insights and methodologies of disciplines such as climatology, water resource systems, ecohydrology, geomorphology, soil science, instrumentation and remote sensing, data and information sciences, civil and environmental engineering are within scope. Social science perspectives on hydrological problems such as resource and ecological economics, sociology, psychology and behavioural science, management and policy analysis are also invited. Multi-and interdisciplinary analyses of hydrological problems are within scope. The science published in the Journal of Hydrology is relevant to catchment scales rather than exclusively to a local scale or site. Studies focused on urban hydrological issues are included.
