While this is just a label, municipalities in California have been banning use of gas appliances in homes for new construction and significant renovations. It was recently overturned by a court decision, so the proponents do want this to be coercive.

I am not remotely convinced there is any need to do this. Code updates for improved ventilation in kitchens, okay, but you're going to have a hard time convincing my that my grilled cheese destroyed the environment significantly more with gas than electric.

I suspect these petty heavy-handed bureaucratic moves will make enemies out of regular people (try cooking with a round bottomed wok on electric) for no real gain. I'm increasingly feeling resentful of these sorts of things.
