Climate change is increasingly governed through local configurations that are characterised by voluntary action, weak institutions and uncoordinated efforts. The impermanent and iterative nature of such initiatives makes it difficult to determine their enduring and potentially transformative impact. This review systematises how the sustainability transitions field has approached temporary initiatives. It finds broad agreement on the difficulty of sustaining local transitions, but little analytical engagement with how temporary initiatives shape transition pathways over time. The review therefore proposes a typology of temporal dimensions to help assess the dynamics between ephemerality and permanence in local transitions. By mapping the recent empirical sustainability transitions literature along these dimensions, ephemerality is found to be ubiquitous in local initiatives–there is a lot happening that does not endure but serves other functions. Actors deploy a range of local strategies directed at either formalising initiatives or retaining relevance by reinventing themselves, thus routinising sustainability transitions.

气候变化越来越多地通过以自愿行动，薄弱的机构和不协调的努力为特征的地方格局来治理。这些倡议的无常性和反复性使得难以确定其持久性和潜在的变革性影响。这篇综述系统地描述了可持续性转型领域如何采取临时措施。它发现在维持地方过渡的难度方面达成了广泛共识，但是对于临时性倡议如何随着时间形成过渡路径的分析投入很少。因此，本综述提出了时间维度的类型学，以帮助评估局部过渡中的短暂性和永久性之间的动态关系。通过绘制这些维度上最近的经验性可持续性转型文献，人们发现，在地方计划中普遍存在短暂性，这种情况并不持久，但起着其他作用。参与者部署了一系列针对正式计划或通过重塑自我来保持相关性的本地策略，从而实现了可持续性转型。
