I think the real situation is more depressing than that. Behavioural change won't matter unless the whole world does it. The rate of new global carbon emissions is increasing. This is despite any efforts to be greener or more renewable by individuals or institutions. Why? Because there's demand for fossil fuels, it's legal to produce it. How will changing individual behaviour in the west reduce global emissions or even slow their rate of growth? (Am assuming you're western) I'm being a bit too pessimistic of course. If individuals in the west create demand for technologies that work better than fossil fuels, then we could reduce global emissions. So behavioural changes could help with that. But as long as carbon benefits some places that need energy, it will be used. That's at least what we've seen over the past 30 years the world has focussed on reducing annual carbon emissions. They've increased instead.
