Considering no amount of lifestyle changes will put a dent in the carbon problem, I would expect a seriously concerned climate scientist to spend their energy advocating for the only thing that will make a difference: top down policy change (carbon pricing or clean energy mandates or similar). That said, if I were a prominent polluter, I would want people to think that this is all a matter of lifestyle changes so I could keep on polluting while shaming you into some miserable vegan existence. :)
