This publication, Guidelines for Climate Proofing Investment in the Transport Sector: Road Infrastructure Projects, aims to present a step-by-step methodological approach to assist project teams to incorporate climate change adaptation measures into transport sector investment projects. While the focus of the publication is on the project level, an improved understanding of climate change impacts should also be used in the design of infrastructure planning and development policies and strategies to ensure appropriate resource allocation. Though the transport sector includes roads, waterways, rails, and airborne transport, this publication focuses solely on road infrastructure.
