Why Experts Say It’s Time to Move Beyond Gas Stoves
A comprehensive examination of the health, safety, and climate risks posed by gas stoves and the growing push for safer, cleaner alternatives.
Why More People Are Questioning the Safety of Gas Stoves
For most of the 20th and 21st centuries, gas stoves have stood as a staple of American and global kitchens, prized for their responsiveness and culinary performance. However, accumulating scientific evidence and rising awareness about the pollutants emitted by gas stoves have led experts and public health advocates to call for a fundamental reevaluation of their role in our homes.
Concerns have moved beyond anecdote: agencies, health officials, and even major media outlets—including the New York Times—now cite growing evidence that gas stoves are hazardous to human health and the environment.
The Hidden Dangers Inside Your Kitchen
When you switch on a gas stove, you’re not just cooking—you’re releasing a cocktail of combustion byproducts and toxic pollutants into your home. The most concerning emissions include:
- Nitrogen dioxide (NO2): An irritant linked to asthma and respiratory illness.
- Carbon monoxide (CO): A colorless, odorless gas that can be deadly at high concentrations.
- Particulate matter (PM): Tiny particles that penetrate deep into the lungs.
- Formaldehyde, benzene, and other volatile organic compounds (VOCs): Some are known or suspected carcinogens.
A major study by the Harvard T.H. Chan School of Public Health found that people living with gas stoves may regularly breathe in levels of nitrogen dioxide that exceed what is considered safe by both the World Health Organization and the U.S. Environmental Protection Agency. This risk is particularly acute in smaller homes, where concentrations rise more rapidly and remain elevated for longer periods.
Who Faces the Greatest Risk?
Although anyone in a household with a gas stove can be exposed to harmful pollutants, certain groups are especially vulnerable:
- Children, whose lungs and immune systems are still developing.
- People with pre-existing respiratory conditions, such as asthma or COPD.
- Lower-income families, who may have fewer resources to improve ventilation or replace appliances.
- Residents of smaller homes or apartments, where toxic gases can build up more quickly.
A 2024 national assessment concluded that NO2 exposure from gas stoves is up to four times higher for those in homes under 800 square feet, and 60% higher for American Indian and Alaska Native households. Black and Hispanic/Latino households also show significantly elevated exposures.
From Asthma to Cancer: What Does the Research Say?
Multiple epidemiological studies and meta-analyses have found links between exposure to gas stove emissions and adverse health outcomes:
- Childhood Asthma: Recent estimates attribute at least 50,000 current U.S. childhood asthma cases directly to NO2 from gas stoves. Including other pollutants, the total may approach 200,000 cases.
- Lung Diseases: NO2, CO, and particulates can trigger or exacerbate asthma, COPD, and may increase the risk of lung cancer.
- Other Conditions: There’s emerging evidence of links to diabetes, preterm birth, and even neurodevelopmental problems in children.

Harvard scientist Kari Nadeau summarized the consensus: “There really is no safe amount of exposure to these toxicants produced by gas or propane, or any fossil fuel, outside or inside.”
The Environmental and Climate Impact of Cooking with Gas
Beyond indoor air quality, gas stoves contribute to climate change and broader air pollution. Here’s how:
- Methane leaks: Methane, the main component of natural gas, is a potent greenhouse gas. Stoves leak methane even when not in use.
- Combustion emissions: Burning gas generates CO2 and NOx (precursors of smog).
- Fossil fuel demand: Widespread use locks homes into gas utility dependence, slowing the adoption of cleaner infrastructure.
Gas stoves may represent a relatively small fraction of a household’s total emissions compared to heating or hot water, but tens of millions of stoves nationwide contribute to the cumulative problem.
How Did Gas Cooking Become Standard?
The rise of the gas stove can be traced to successful 20th-century marketing campaigns that praised gas as a modern, efficient, and clean way to cook. These efforts led to widespread adoption, despite key differences in safety and health effects compared to electric alternatives.
Over time, a cultural narrative emerged equating gas stoves with higher status and superior cooking results—a perception that continues to shape policy and individual choices today.
Changing Attitudes and Major Media Attention
The tide is turning. In recent years, prominent newspapers and magazines—including The New York Times—have run investigative features and opinion pieces highlighting the risks associated with gas stoves. Medical and environmental organizations are amplifying the message: for the protection of families and the climate, the age of gas cooking should end.
State and federal agencies are joining the conversation. Reports from the U.S. Consumer Product Safety Commission and the American Medical Association have warned about the dangers posed by gas stove emissions.
Policy Shifts and Legislative Action
Legislators are increasingly taking notice. In New York, lawmakers have proposed the Healthy Homes Right To Know Act, which would require prominent labels and safety warnings on all gas stoves sold or displayed. The intention is to ensure that consumers are aware of the risks before purchase and to encourage adoption of safer alternatives.
Key elements of recent legislative proposals include:
- Mandatory warning labels on all new gas stoves.
- Education campaigns about the health impacts of combusting gas indoors.
- Penalties for retailers who fail to comply.
Such laws are part of a broader wave of building code reforms and appliance standards emerging in states like California, which increasingly emphasize electrification of homes and buildings.
Electric and Induction Cooking: Modern Alternatives
Given the mounting evidence against gas, attention is shifting to safer, cleaner alternatives:
- Electric resistance ranges: Familiar, reliable, generating no indoor combustion pollutants.
- Induction cooktops: Rely on electromagnetic fields to heat pans, offering rapid response, precise temperature control, and improved energy efficiency over both gas and conventional electric.
Advantages of induction and modern electric cooking include:
- No indoor air pollution from combustion.
- Improved safety—reduced risk of burns, fires, or gas leaks.
- Potential for lower energy costs, especially with renewable electricity sources.
Table: Gas vs. Electric vs. Induction Cooking
| Feature | Gas Stove | Electric Stove | Induction Cooktop |
|---|---|---|---|
| Outdoor air pollution | High (methane, NO2, CO) | Very low (power plant dependent) | Very low (power plant dependent) |
| Indoor air pollution | High | None | None |
| Climate impact | High | Medium (varies by grid) | Lowest (with renewables) |
| Cooking performance | Responsive, visible flame | Slower response | Fastest, precise control |
| Safety | Fire, burn, leak risks | Hot surface | Cool surface, auto shutoff |
Steps Consumers Can Take Right Now
If you currently use a gas stove and cannot immediately replace it, here are actionable strategies to reduce risks:
- Use exhaust ventilation every time you cook. A range hood that vents to the outside is best—but even window fans can help.
- Open windows when weather and safety allow to increase air exchange.
- Cook on the back burners, where fumes are more likely to be drawn up by a hood.
- Consider using portable induction burners for frequent tasks.
- Have gas appliances inspected regularly, and check for leaks.
- Avoid burning candles or using indoor fireplace while cooking to decrease overall indoor pollution.
If you are planning a kitchen renovation or buying new appliances, choose electric or induction options whenever possible for your family’s long-term health and safety.
