Gas Stoves and Indoor air Pollution: A National Health Risk
For manny people in the United States,spending time indoors dose not guarantee protection from harmful air pollution. A new study led by Stanford University and published December 2, 2023, in PNAS Nexus reports that gas and propane stoves release significant amounts of nitrogen dioxide.This pollutant has been associated with asthma, obstructive pulmonary disease, preterm birth, diabetes, and lung cancer. According to the research, switching from gas to electric stoves lowers nitrogen dioxide exposure by more than one quarter nationwide and by about half for people who use their stoves most frequently.Earlier studies documented nitrogen dioxide from gas stoves, but this work is the first to examine both indoor and outdoor exposure across the entire country.
The findings: Nitrogen Dioxide and Gas Stoves
The Stanford-led study, national exposure to nitrogen dioxide from gas stoves
, published in PNAS Nexus, reveals a concerning link between gas stove usage and indoor nitrogen dioxide (NO2) levels. Senior author Rob Jackson, the Michelle and Kevin Douglas Provostial Professor in Earth System Science at the Stanford Doerr School of Sustainability, stated, “we know that outdoor air pollution harms our health, but we assume our indoor air is safe.” The research demonstrates that gas stove use can generate NO2 concentrations comparable to those found in outdoor air, even in well-ventilated homes.
The study utilized a combination of modeling and real-world measurements to estimate NO2 exposure from gas stoves across the U.S. Researchers considered factors like stove usage frequency, home ventilation rates, and outdoor NO2 concentrations. The results indicate that approximately 18.8% of U.S. homes have gas stoves, contributing considerably to indoor air pollution.

| Scenario | National NO2 Reduction | Reduction for Frequent Stove Users |
|---|---|---|
| Switch to Electric Stoves | >25% | ~50% |
Indoor Pollution: A Hidden Danger
While outdoor air pollution is a well-recognized public health concern, indoor air quality often receives less attention. The U.S. Environmental Protection Agency (EPA) estimates that Americans spend approximately 90% of their time indoors, making indoor air quality a critical determinant of overall health. The EPA provides resources on indoor air quality, but regulation remains limited.
Laws like the U.S. Clean Air Act have demonstrably improved outdoor air quality, reducing the incidence of respiratory illnesses and other health problems. Though,indoor air pollution sources,such as gas stoves,cleaning products,and building materials,are frequently enough unregulated,posing a significant risk to public health. Outdoor air pollution contributes to hundreds of thousands of deaths in the U.S. each year and leads to millions of new cases of childhood asthma worldwide, according to the
