The German Longitudinal Environmental Study (GLEN)

气候变化和地球自然资源的枯竭是人类目前面临的最大挑战。有鉴于此，计划中的德国纵向环境研究（GLEN）旨在调查人与环境相互作用背后的激励、限制、态度和信念。在这样做的过程中，GLEN旨在为基于证据的环境政策评估和指导提供基础。该项目将对成年德国人口进行大规模的小组研究，使用标准化和稳定的调查工具对同一个人进行长期反复观察。由于其纵向设计和收集的调查数据与受访者的社会和生态环境的地理空间信息的联系，该小组将非常适合于分析自然实验，如区域政策措施（如价格变化、信息活动）和对当地环境条件的暴露（如极端天气事件）。此外，该小组将被用作调查实验的平台，以调查环境偏好，消费决策以及对环境技术和政策的接受程度的权衡。通过这种设计，GLEN将满足环境社会科学中对适合因果研究和模拟的数据的迫切需求。有了定期的茶点样品，它将允许持续监测环境问题和行为的趋势，同时也考虑到不同的社会、政治、经济和心理方面。因此，GLEN主要被理解为所有社会科学学科的环境研究的数据基础设施。这些数据可以解决的关键问题包括：是什么影响环境问题、行为以及对保护环境的技术和政策的接受程度？环境政策和不断变化的环境对社会不平等有什么影响，这如何影响（感知的）环境正义？GLEN是一个长期项目，将涵盖2024年至2035年，这是根据国际协议实施替代化石燃料的决定性政策措施的时期。总而言之，该项目包括三个工作流程，以实现三个密切相关的目标：(I)首先，该项目将为环境社会科学建立数据基础设施，不仅在德国，而且在国际范围内。（二）项目数据将用于环境社会科学的实质性研究。（三）通过定期趋势报告和嵌入式实验，提供循证政策评估和指导。

Climate change and the depletion of the Earth’s natural resources are among the largest challenges humanity currently faces. In light of this, the planned German Longitudinal Environmental Study (GLEN) aims at investigating the incentives, restrictions, attitudes, and beliefs that underlie human-environment interactions. In doing so, the GLEN aims to provide a foundation for evidence-based environmental policy assessments and guidance. The project will build up a large-scale panel study of the adult German population in which the same individuals will be repeatedly observed over time using a standardized and stable survey instrument. Due to its longitudinal design and the linkage of the collected survey data to geospatial information on respondents’ social and ecological environments, the panel will be well suited to analyzing natural experiments such as regional policy measures (e.g., price changes, information campaigns) and exposure to local environmental conditions (e.g., extreme weather events). In addition, the panel will be used as a platform for survey experiments to investigate trade-offs in environmental preferences, consumption decisions, and the acceptance of environmental technologies and policies. With this design, the GLEN will meet the urgent need for data suitable for causal research and simulations in the environmental social sciences. With regular refreshment samples, it will allow for the continuous monitoring of trends in environmental concern and behavior, while also considering diverse social, political, economic, and psychological aspects. Accordingly, the GLEN is primarily understood as a data infrastructure for environmental research across all social science disciplines. Key questions that can be addressed with the data include: What influences environmental concern, behavior, and the acceptance of technologies and policies to protect the environment? What consequences do environmental policies and changing environments have for social inequalities, and how does that affect (perceived) environmental justice? As a long-term project, the GLEN will cover the period between 2024 and 2035, and thus the period in which decisive policy measures to replace fossil fuels are set to be implemented in accordance with international agreements. In sum, the project includes three work streams to pursue three closely related goals: (I) First and foremost, the project will generate a data infrastructure for the environmental social sciences, not only in the German context, but also internationally. (II) The project will use the data for substantive environmental social science research. (III) The project will provide evidence-based policy evaluations and guidance with regular trend reports and embedded experiments.
