Simply running a gas burner generates about twice as much PM2.5 emissions as pan-frying a chicken breast on an induction stove. And of course gas generates pollution when you're boiling or steaming things, quickly reheating, or anything that doesn't involve burning / Malliard reactions / etc. Using gas means you are at the very least doubling the amount of pollution, and in most cases it's much worse than that.
