The accessibility concept provides a suitable framework for the achievement of sustainable land use and transport systems. Environmental and climate concerns have gained particular relevance among sustainability goals in recent years, thus reshaping political agendas all over the world. Against this background, this paper explores the practical relevance of accessibility instruments for low carbon mobility planning. A theoretical framework on usefulness is developed, which outlines potential application purposes related to identifying needs for interventions in the land use and transport system, assessing the impacts of potential solutions, as well as communicating between planning sectors and stakeholders. Three real-world planning issues in the Munich region serve to test the hypothetical usefulness of accessibility instruments for low carbon mobility planning in empirical applications. Practitioners were involved at various stages throughout the process in order to capture their perspectives on practical relevance. Both the identified planning issues and the types of accessibility implementations were diverse in nature, showing that accessibility analysis is applicable to a variety of tasks connected to the aim of reducing transport-related emissions. Earlier findings about the practical relevance of accessibility instruments were confirmed in this context, in particular the importance of communicative outputs. While more research in other spatial contexts is clearly needed, we conclude that accessibility instruments can contribute to a low carbon transition by enabling practitioners to plan for low carbon mobility options and communicate the benefits of these options. However, the implementation of accessibility instruments might be hampered by emerging barriers, such as the need to quantify emissions and emission savings, the desire to consider qualitative aspects in addition to quantitative indicators, and the lack of accessibility standards and reference values.

无障碍概念为实现可持续的土地利用和运输系统提供了一个合适的框架。近年来，环境和气候问题在可持续发展目标中变得尤为重要，从而重塑了世界各地的政治议程。在此背景下，本文探讨了无障碍工具在低碳出行规划中的实际相关性。开发了一个关于有用性的理论框架，它概述了与确定土地使用和运输系统干预需求、评估潜在解决方案的影响以及规划部门和利益相关者之间的沟通相关的潜在应用目的。慕尼黑地区的三个现实世界规划问题有助于测试无障碍工具在实证应用中对低碳交通规划的假设效用。从业者参与了整个过程的各个阶段，以捕捉他们对实际相关性的看法。确定的规划问题和无障碍实施的类型本质上是多种多样的，这表明无障碍分析适用于与减少交通相关排放目标相关的各种任务。早先关于无障碍工具的实际相关性的调查结果在这方面得到了证实，特别是交流输出的重要性。虽然显然需要在其他空间背景下进行更多研究，我们得出的结论是，无障碍工具可以通过使从业者能够规划低碳出行选项并传达这些选项的好处来促进低碳转型。然而，无障碍工具的实施可能会受到新出现的障碍的阻碍，例如需要量化排放和减排量、希望在定量指标之外考虑质量方面以及缺乏无障碍标准和参考值。
