This paper provides a review of resources available for undertaking climate change risk assessments for the transport sector in Britain. The authors undertook research to identify tools and guidance currently available, and used by, all parts of the British transport sector in assessing the risks from climate change to transport infrastructure and operations. Through gathering evidence, expert opinion, and stakeholder engagement a comprehensive list was prepared that covered both physical and transition risks to transport. The review was undertaken in March–July 2023. The authors are aware this is a fast-moving area and anticipate that new tools and guidance may be available at the time of publication. No one tool or guidance was identified that provided output that could be considered best practice for all transport sectors (rail, highways, aviation and ports). However, this paper lays out which items are potentially useful for British transport organisations at different stages and levels of maturity. The paper also highlights where there are gaps in the understanding, usage or existence of tools and guidance and provides recommendations on how these gaps may be filled.
