The Average Annual Loss (AAL) serves as an indicator of anticipated yearly losses over an extended period, determined through probabilistic risk models. In the present global environmental landscape, the AAL for crucial infrastructure sectors totals approximately $300 billion.
When factoring in buildings, along with health and education infrastructure, the overall AAL for infrastructure surpasses $750 billion, making up roughly 14 percent of the global GDP growth for 2021-2022. It's important to highlight that this estimate errs on the side of caution by excluding losses in agriculture, natural capital, and specific small-scale extensive risks.
