Based on economic and ecological criteria this paper proposes an evaluation framework for the provision of green electricity for charging plug-in electric vehicles in Germany, using the Analytic Hierarchy Process approach for a Multi-Criteria Decision Analysis. The framework allows for a transparent evaluation of the supply of green electricity for electric vehicles from different stakeholder perspectives, without the direct involvement and reassessment by the experts. The relevant criteria for the evaluation are derived from literature, an analysis of eco-labels for electricity tariffs, and 33 expert interviews from four different stakeholder groups (municipal utilities, academia and science, non-governmental organizations, and automobile manufacturers). Eight criteria have been found to be particularly relevant for green electricity service evaluation: regionality, transparency, balancing period, additionality, land use, greenhouse gas emissions, smart charging (via a flexibility discount), and quality premium. The evaluation framework comprises value scores, which represent the degree to which a specific green charging service satisfies a given quality criterion, and combines them with the weights derived in the Analytic Hierarchy Process. The results differ markedly between stakeholder groups and point to the particular importance of additionality, technology-specific greenhouse gas emissions, and transparency. The framework seems useful for service design by (municipal) utilities, charge point operators, non-governmental organizations, and aggregators offering smart charging solutions.

基于经济和生态标准，本文提出了一种用于评估德国插电式电动汽车充电的绿色电力的评估框架，该方法采用层次分析法进行多标准决策分析。该框架允许从不同利益相关者的角度透明评估电动汽车的绿色电力供应，而无需专家的直接参与和重新评估。评估的相关标准来自文献，对电价的生态标签的分析以及来自四个不同利益相关者团体（市政公用事业，学术和科学，非政府组织和汽车制造商）的33次专家访谈。区域性，透明度，平衡期，额外性，土地使用，温室气体排放，智能充电（通过灵活性折扣）和质量溢价。评估框架包括价值评分，这些评分代表特定绿色充电服务满足给定质量标准的程度，并将它们与“分析层次结构”过程中得出的权重相结合。利益相关者群体之间的结果明显不同，并指出了额外性，特定于技术的温室气体排放和透明度的特别重要性。该框架似乎对于（市政）公用事业，充电点运营商，非政府组织和提供智能充电解决方案的聚合商的服务设计很有用。
