Wildfires in the United States are growing larger and the fire season is lasting longer due to hotter and drier weather driven by climate change. Even when fires burn hundreds of miles away, wildfire smoke can travel and settle over cities, creating severe air pollution. According to experts, this smoke threatens public health and creates significant economic challenges.
The Air Quality Index normally stays low for clean air, but wildfire smoke can push those numbers much higher. While environmental regulations significantly improved air quality over the past 40 years, wildfire smoke is now eroding those gains. Recent research demonstrates that smoke has erased about a quarter of that historical progress, and more than half in many western states.
Wildfire smoke impacts the economy through three main channels:
- Reduced spending: When air pollution peaks, people stay indoors, leading to fewer customers for local businesses and the cancellation of outdoor events.
- Reduced productivity: Breathing polluted air makes it harder to focus, while outdoor sectors like construction and agriculture face reduced labor participation and safety-related work cancellations.
- Increased health care costs: Exposure to wildfire smoke costs billions of dollars annually in respiratory illnesses and hospital admissions.
These higher levels of exposure disproportionately affect lower-income households, as many workers cannot work remotely or afford to take a day off. As smoky days become more common, experts anticipate ongoing disruptions to outdoor labor, school closures, and reduced overall economic activity.
