Adapting Transport to Climate Change and Extreme Weather

Implications for Infrastructure Owners and Network Managers

This report addresses the fundamental challenges that climate change poses to infrastructure owners, who face two major challenges. First, they must ensure continued asset performance under sometimes significantly modified climate conditions that may decrease the present value of their networks or increase maintenance and refurbishment costs. Second, they must build new assets in the context of changing and uncertain climate variables. This creates a risk of over- or under-specification of infrastructure design standards, potentially resulting in non-productive investments or network service degradation. This report investigates strategies that can help transport authorities contain network performance risks inherent in changing patterns of extreme weather.



Managing climate change uncertainty in transport infrastructure design and network planning

International Transport Forum

Managing uncertainty is not a new aspect of transport policy – considerable climate change uncertainty surrounds future demand projections and the global trends that can impact flows of people and goods. There is also micro-level uncertainty on how specific parts of the transport networks may be affected by disruptions. Addressing these incidents and sources of uncertainty lies at the heart of transport decision making. This chapter looks at strategies including, but not limited to, cost-benefit analysis to address this “deep” uncertainty for transport infrastructure and services whose life-times extend well into the future.
