In terms of Indoor Air Quality (IAQ), gas stoves are a pretty. It's not just CO2 you need to worry about. Burning natural gas releases a whole mess of pollutants. It's wise to open up a window if you're using the stove or oven and you don't have a direct-exhaust hood.
In terms of actual cooking, I love gas stoves. They heat up and shut off immediately through the twist of the knob. Electric resistance range tops are so annoying - they take forever to heat up and cool down. I hear induction is very gas-like in terms of its response, but it only works with ferrous metals. So it's a no-go for copper, aluminum, or clay.
As homes become more airtight, the issue with bad IAQ becomes more pertinent, especially as the public becomes more aware of the effects of bad IAQ. We know CO2 as a greenhouse gas, but don't typically think of it as a poison that can affect our mental faculties in high-enough concentrations. We are also blissfully unaware of the amount of pollutants released by burning gas. In addition, there's also the pollutants that come from the actual cooking of food itself.
