Gas Stove Users Are Exposed to Higher Indoor NO₂ Levels
Across 3-digit ZIP codes, gas stove users are exposed to higher average NO₂ levels than the general population—even after accounting for population size. This comparison reflects not just ZIP-level concentrations, but how many people are affected in each area.
A ZIP3-level choropleth map of the United States showing modeled long-term NO₂ exposure levels. ZIP3 regions are shaded from light to dark, with darker areas indicating higher NO₂ exposure. Tooltips display the ZIP3 code and modeled NO₂ concentrations for all households, gas stove users, and heavy gas stove users. The map illustrates that ZIP3 areas with higher gas stove usage tend to show greater NO₂ exposure.
