Decisions about infrastructure should consider relevant uncertainties to ensure resilience across a range of potential future scenarios. Uncertainties should be clearly communicated and valued, and there should be access to the tools needed to support decision-making under uncertainty. The use of platforms and online tools can provide accessible, credible and transparent information on past and future climate behaviour. The risks from climate change are diverse, vary by national circumstances and there are multiple possible metrics for measuring progress in addressing those risks. Nature-based, flexible or innovative approaches to climate-resilient infrastructure may even be cheaper than traditional approaches. Global studies find that the benefits of investing in resilience outweigh the costs with high benefit-cost ratios, for example of investment in flood defences for coastal cities.
