Up to 12 per cent of childhood asthma is connected to gas stove emissions, says Climate Council

But that's beginning to change.

Gas stoves release a number of dangerous substances including carbon monoxide, nitrogen dioxide and formaldehyde, CHOICE household product manager Chris Barnes told ACM.

Regulations are in place to minimise gas stove emissions, he said.

"Nevertheless, if you're running gas appliances in the house you are adding to indoor air pollution," Mr Barnes said.

"The main problem is a gas heater or cooktop that isn't performing properly," he said.

Air pollution contributes to around 3,000 deaths per year nationally, Asthma Australia CEO Michele Goldman told ACM.

And these deaths are not limited to respiratory disease - cardiovascular disease and cancer have also been linked, she said.

"When we breathe in pollutants, they don't just stay in our airways," Ms Goldman said.

"They can cross over into our bloodstream and travel to other organs in the body," she said.

A report published by the Climate Council estimates up to 12 per cent of childhood asthma is connected to gas stove emissions.

Our airways are sensitive and there are a range of triggers that can cause symptoms and flare-ups, Asthma Australia's Ms Goldman said.

"Emissions from gas cooktops and heaters are key contributors," she said.

"Children are particularly impacted because they have smaller airways," she said.

Asthma and allergy sufferers breathing gas emissions can irritate airways, cause inflammation and make it difficult to breathe, she said.

Induction is one technology that is featuring in new kitchen design, both domestic and commercial, as an alternative to gas.

The cooktops channel heat through the base of a pan, but are not hot to touch.

Induction uses electricity to generate heat, rather than burning natural gas.

"I say to anyone who's renovating, install induction," chef Christine Manfield told ACM.

"They tell me what a great decision it was and how happy they are," she said.

They are quick to clean, safer in clumsy hands and can reach high temperatures in record time, she said.

"It's got a safety mechanism that cuts the heat off when you're not using it," Ms Manfield said.

"They cook more evenly and reach a high heat more quickly than gas stoves," she said.

Induction stoves barely create ambient heat, which may not seem important in domestic kitchens but is a game-changer in heaving, hot commercial kitchens, she said.
