I would be more than happy to give up almost everything if it would stop climate change, but unfortunately even if I make all those changes, everybody else will continue driving cars, so it seems my personal choices have nothing to do with whether global warming happens or not. The way around this is collective (government) action to guarantee everyone will participate, but for a variety of reasons we don't have the political will to make that happen. Besides, I'm not convinced individuals' actions are to blame for the majority of climate change -- I'm not an expert but I'm under the impression that corporate / industrial energy usage is the majority of the problem.
consumer's demand is indeed part of the problem, but the corporate/industrial's perpetual quest for growth is also part of it IMHO. if corporations are okay with not growing, planned obsolescence won't be a thing and we will also probably get less ads shoved on our face to trigger our impulse to buy.
