According to this new report by the National Institute of Building Sciences, when the Feds spend a $1 on mitigation grants (to address foreseeable natural disasters including those caused by climate change), they save us $6 on future disaster costs. And when communities build these strategies into their building codes, that can save $4 on each dollar spent. Both strategies together could save 600 lives and a million injuries.

And here's a more detailed summary from their page:
More than a decade after releasing its original report on mitigation, the National Institute of Building Sciences issued Natural Hazard Mitigation Saves: 2017 Interim Report. The 2017 Interim Report highlights the benefits of two mitigation strategies. The Institute's project team looked at the results of 23 years of federally funded mitigation grants provided by the Federal Emergency Management Agency (FEMA), U.S. Economic Development Administration (EDA) and U.S. Department of Housing and Urban Development (HUD) and found mitigation funding can save the nation $6 in future disaster costs, for every $1 spent on hazard mitigation.
In addition, the project team looked at scenarios that focus on designing new buildings to exceed provisions of the 2015 model building codes. The 2017 Interim Report demonstrates that investing in hazard mitigation measures to exceed select requirements of the 2015 International Codes (I-Codes), the model building codes developed by the International Code Council (ICC), can save the nation $4 for every $1 spent.
The project team estimated that just implementing these two sets of mitigation strategies would prevent 600 deaths, 1 million nonfatal injuries and 4,000 cases of post-traumatic stress disorder (PTSD) in the long term. In addition, designing new buildings to exceed the 2015 International Building Code (IBC) and International Residential Code (IRC) would result in 87,000 new, long-term jobs and an approximate 1% increase in utilization of domestically produced construction material.
