The energy transition has seen greater progress in some areas than others. Although it accounts for a significant portion of global greenhouse gas emissions, the transportation sector has hardly broken its high dependence on oil. Within the transportation sector, passenger road transport plays a considerable role in terms of both energy consumption and emissions. This paper, therefore, aims to contribute to the knowledge and theory of sustainability transitions in passenger road transportation by addressing the question, “How do actors and technologies interact to shape the process of sustainability transitions in road transport?” To help answer this question, Actor-Network Theory is applied to a local-level case study of an electric carsharing company in Brno, Czech Republic. A review of the energy transitions literature revealed ANT as a fruitful methodological toolbox due to its unique ontology and concepts. The study reveals that both the human and non-human actors within this network indeed play crucial roles that influence its successful expansion. These roles are often contested and negotiated by the various actors, thereby dictating the development of these associations as well as the actor-network as a whole. Moreover, the roles and associations within this network in many instances emerge not through human intention or agency but in response to those negotiated issues particularly surrounding the material elements of the network. While the study focuses on a specific case, it also offers insights and lessons for the broader energy transition, particularly the process of such transition in passenger road transportation.

能源转型在某些领域取得了比其他领域更大的进步。尽管它占全球温室气体排放量的很大一部分，但运输部门几乎没有打破其对石油的高度依赖。在运输部门中，公路客运在能源消耗和排放方面都起着相当重要的作用。因此，本文旨在通过解决以下问题为客运道路运输中的可持续性转变的知识和理论做出贡献：“参与者和技术如何相互作用以塑造道路运输中可持续性转变的过程？” 为了帮助回答这个问题，Actor-Network Theory被应用于捷克共和国布尔诺的一家电动汽车共享公司的本地案例研究。对能量跃迁文献的回顾表明，由于ANT具有独特的本体论和概念，它是一个富有成果的方法论工具箱。该研究表明，该网络中的人类和非人类参与者的确扮演着影响其成功扩张的关键角色。这些角色通常由各种参与者竞争和协商，从而决定了这些协会以及整个参与者网络的发展。而且，在许多情况下，此网络中的角色和关联不是通过人的意图或代理而出现的，而是对那些围绕网络实质要素的协商问题做出的响应。该研究着眼于特定案例，同时也为更广泛的能源转型提供了见识和教训，
