This study explores how environmental knowledge and risk perception influence individuals' sustainable consumption behavior through the mediation of environmental concern and behavioral intention. The study combines constructs from earlier studies to form a novel theoretical model, which is tested and validated with an open data set from the Environment III 2010 module, which was collected by the International Social Survey Programme (ISSP). Our sample consists of respondents from nine countries (N = 11,675) in the European Union (EU) and the European Free Trade Association (EFTA). The model indicates that environmental risk perception and environmental knowledge impact environmental concern significantly. Furthermore, environmental concern strongly influences behavioral intention, and these constructs, in turn, act as mediators of sustainable consumption behavior. The findings indicate that in Europe, sustainable consumption behavior can be associated with environmental concern, which is influenced by increased levels of environmental knowledge and environmental risk perception. The results provide a basis for future analyses once the Environment IV module is released. This will be of particular importance for tracking possible changes in the sustainable consumption behavior of Europeans when transitioning to a green and circular economy that is driven by the European Green Deal and EU Circular Economy Action Plan.

本研究通过环境关注和行为意向的中介，探讨环境知识和风险感知如何影响个人的可持续消费行为。该研究结合了早期研究的结构，形成了一个新的理论模型，该模型通过来自国际社会调查计划 (ISSP) 的 Environment III 2010 模块的开放数据集进行测试和验证。我们的样本由来自九个国家（N = 11,675) 在欧盟 (EU) 和欧洲自由贸易联盟 (EFTA)。该模型表明，环境风险感知和环境知识显着影响环境关注。此外，环境关注强烈影响行为意图，而这些结构反过来又充当可持续消费行为的中介。研究结果表明，在欧洲，可持续消费行为可能与环境问题有关，这受到环境知识和环境风险感知水平提高的影响。一旦环境 IV 模块发布，结果将为未来的分析提供基础。
