Our society is facing serious environmental challenges related to climate change, pollution, diminishing resources, and biodiversity loss. Such problems are often ill-defined and are characterized by high uncertainty. Environmental decisions have strong impacts on society and demand clear and transparent trade-offs across values and priorities of stakeholder groups. This Feature Issue on Environmental Decisions includes papers focused on important environmental applications approached through various disciplinary backgrounds. The papers highlight advanced–often interdisciplinary–methodological approaches and include the perspectives of different stakeholders in the process of environmental decision-making. A wide range of methods are explored, ranging from a comprehensive review (for sustainable transport by Marleau Donais et al.) to an opinion paper proposing the use of Records of Engagement and Decision-making (RoED; by Cockerill et al.). Stakeholder engagement and preference elicitation required the development of new aggregation models for Multi-Criteria Decision Analysis (MCDA; by Reichert et al.). The integration of Cost-Benefit Analysis (CBA) with MCDA was found to be necessary in practice (by Liu et al.; Marleau Donais et al.). MCDA was extended to include the spatial dimension by integrating Geographic Information Systems (GIS; by Guay et al.; Schito et al.). The importance of considering the resilience of systems to better respond to and recover from unpredictable risks was emphasized (by Leyerer et al.; Mustajoki and Marttunen). These papers demonstrate the richness of approaches to environmental decision-making. Environmental issues offer ample exciting research opportunities to a broader scientific community. We encourage the readers of this Feature Issue—and of EJDP—to engage in environmental decision-making projects to support emerging societal needs.

我们的社会正面临着与气候变化，污染，资源减少和生物多样性丧失有关的严重环境挑战。这样的问题通常是不确定的，并且具有很高的不确定性。环境决策对社会具有重大影响，需要在利益相关者群体的价值观和优先事项之间进行清晰透明的权衡。本期《环境决策专题》包括针对通过各种学科背景进行的重要环境应用研究的论文。这些论文重点介绍了先进的（通常是跨学科的）方法论方法，并包括了环境决策过程中不同利益相关者的观点。探索了多种方法，包括全面的综述（Marleau Donais等人的可持续运输）。）提出建议使用参与和决策记录（RoED； Cockerill等人）的意见书。利益相关者的参与和偏好激发需要开发用于多标准决策分析（MCDA； Reichert等人）的新汇总模型。实践中发现，将成本效益分析（CBA）与MCDA集成是必要的（Liu等人； Marleau Donais等人）。通过集成地理信息系统（GIS； Guay等人； Schito等人），将MCDA扩展为包括空间维度。强调了考虑系统的弹性以更好地应对不可预测的风险并从中恢复的重要性（Leyerer等人； Mustajoki和Marttunen）。这些论文证明了环境决策方法的丰富性。环境问题为更广泛的科学界提供了足够激动人心的研究机会。我们鼓励本期特刊和EJDP的读者参与环境决策项目，以支持新兴的社会需求。
