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.

Policy Insights

  • Act now to preserve the value of transport infrastructure and maintain network performance.
  • Protect transport infrastructure against climate impacts through good maintenance.
  • Prepare for more frequent and unexpected failure of transport infrastructure.
  • Account for temporary unavailability of transport assets in in service continuity plans.
  • Assess vulnerability of transport assets and networks from climate change and extreme weather.
  • Focus on transport system resilience, not just on designing robust infrastructure.
  • Re-evaluate thinking on redundant transport infrastructure.
  • Do not rely solely on cost-benefit analysis for appraising the value of transport infrastructure.
  • Develop new decision-support tools that incorporate deep uncertainty into asset appraisal.
