While economic analysis methods such as cost-benefit and economic impact assessments are well established, their application to climate change impacts on transportation infrastructure is less developed.

This guide focuses on aiding practitioners to better understand how to reveal the economic implications of both ongoing damages to transport infrastructure and the benefits of investing to improve infrastructure resiliency.

The guide includes: a taxonomy of economic benefits from transportation infrastructure, relating these benefits to costs as climate change alters infrastructure services and triggers additional costs; an exploration of the economic toolkit; a step-by-step approach to conducting a climate risk assessment; and some further thoughts on the process.
