The purpose of this legislation, known as the "Measuring the Cost of Disasters Act of 2025," is to create a public database and webpage that provides detailed information about billion-dollar disasters occurring in the United States each year. The goal is to improve transparency and accessibility of data related to significant disasters, which can help in understanding their impact and in planning for future events. Key provisions of the legislation require the National Oceanic and Atmospheric Administration (NOAA) to establish and maintain this database and webpage.
