1. Gas stoves emit CO2 and likely Methane due to leaks. In fact, methane (natural gas is just methane) is a very potent greenhouse gas and the methane industry leaks a significant percent every year. So having lots of gas infrastructure basically guarantees a bunch of methane will leak into the atmosphere. I doubt the stove-only emissions are an appreciable percent of global emissions, but I'll take a 2% reduction. However, there is a follow on effect. Each utility we transition off of direct fossil fuels results in economiesof scale moving away from fossil fuel to electricity (and hopefully clean power generation). So in the medium-term the effect could be multiplied. 2. Burning methane in your house is going to cause some pollution. Methane isn't pure, so other stuff is likely getting burned too. I mean, just logically lighting a fire in your house is probably not going to be good for your health in general. As for "should we regulate this". It depends on perspective. The gas lobby has worked hard and spent a lot of money to trick people like you into to thinking gas stoves can compete with induction ranges. They cannot. Induction ranges are cheaper, more energy efficient, safer, and healthier than gas stoves. Installing a gas stove in 2023 is using an inferior technology either because of ignorance or Nostalgia. Now, you could argue that it's the right of each citizen to choose to make bad decisions. In this case, however, that bad decision perpetuates an unsustainable energy apparatus. So I would argue the public good outweighs the homeowner's (or more likely, corporate landlord's) ability to make bad decisions.
