Climate change threatens nearly one third of U.S. hazardous chemical facilities

Nearly one third of the hazardous chemical facilities in the United States are at risk from climate-driven floods, storms and wildfires, according to a new analysis by the Government Accountability Office.

The federal watchdog analyzed more than 10,000 factories, refineries, water treatment plants and other facilities that manufacture, store or use dangerous chemicals. They found that more than 3,200 of them are located in places where they face damage from sea level rise, hurricane storm surge, wildfires or flooding from heavy rain.

“Recent natural disasters have demonstrated the potential for natural hazards to trigger fires, explosions, and releases of toxic chemicals at facilities,” the report’s authors note.
