摘要
开展基于区域特点的环境外部性成本的量化对支持可持续技术至关重要。当前我国尚未形成广泛推广应用的本地化环境影响货币化评估方法,现有研究中对部分指标的考量因素仍不够全面、特征物质缺乏代表性,致使部分指标准确性和通用性欠佳。因此,基于生命周期的ReCiPe方法,结合市场价值法和环境税法,优化了陆地生态毒性(TET)等7个环境指标的中国本地化货币权重因子。该方法通过结合中国标准化因子数据库,对气候变化(CC)、颗粒物形成(PMF)、陆地酸化(TA)、化石消耗(FD)、金属资源消耗(MRD)纳入了不同物质对环境指标的影响贡献占比;考虑资源枯竭率、资源存量和产量等关键因素对MRD和FD的影响,提高了货币化因子的准确性和实用性。并更换TET和水资源消耗(WC)的特征物质——采用1,4-二氯苯和工业用水——提高了TET和WC货币化因子在各个领域的适用性。结果显示,MRD的货币化权重因子最高(8.77元·kg^(-1)Cu eq.(铜当量)),FD最低(0.30元·kg^(-1)oil eq.(原油当量)),揭示了资源消耗货币化结果与资源禀赋和市场价格之间的密切关系。为促进清洁能源的可持续发展,以铜铟镓硒(CIGS)报废光伏板回收为案例,开展了环境外部性成本分析。CIGS光伏板回收的环境外部性成本在9.16~20.67元·m^(-2)之间,硫酸和燃煤发电对TET以及CC的环境外部性成本较大,建议采用环保试剂和绿电降低成本。研究结果为完善中国环境影响货币化因子的评估体系提供了新的视角和方法,同时促进光伏废弃物回收管理。
Quantifying regional-specific environmental externality costs is crucial for supporting sustainable technologies.China currently lacks a widely applicable localized methodology for monetizing environmental impacts,with existing studies often constrained by incomplete indicator coverage and unrepresentative characterization factors,leading to compromised accuracy and generalizability.This study optimized the localized monetary weight factors for seven environmental indicators in China,including terrestrial ecotoxicity(TET),based on the life cycle-based ReCiPe method,combined with market value and environmental tax approaches.By integrating China's standardized factor database,this method incorporates the proportionate contributions of different substances to environmental indicators such as climate change(CC),particulate matter formation(PMF),terrestrial acidification(TA),fossil depletion(FD),and metal resource depletion(MRD).It enhanced methodological rigor by 1)incorporating key factors such as resource depletion rates,reserves,and production volumes for MRD and FD,and 2)replacing conventional characterization substances for TET and water consumption(WC)with 1,4-dichlorobenzene and industrial water usage,respectively,to improve crosssectoral applicability.Results revealed MRD exhibited the highest monetary weighting factor(8.77 Yuan·kg^(-1) Cu eq.),while FD showed the lowest(0.30 Yuan·kg^(-1) oil eq.),underscoring the correlation between monetized resource impacts and regional resource endowments and market dynamics.To promote the sustainable development of clean energy,this study conducted an externality cost analysis using the recovery of copper indium gallium selenide(CIGS)waste photovoltaic panels as a case study.The externality cost of CIGS photovoltaic panel recovery ranges from 9.16 to 20.67 Yuan·m^(−2),with sulfuric acid and coal-fired power generation significantly contributing to the externality costs of TET and CC.It was recommended to use ecofriendly reagents and green electricity to reduce costs.This study provided a new perspective and method for improving China’s assessment system for environmental impact monetization factors and simultaneously promotes the management of photovoltaic waste recycling.
