And to be fair, why would China or India care about becoming greener when the United States, with all of their wealth and power, can expel 16.1 tons per capita per year without repercussions while China gets told of for their 8.0 tons? Let alone India, with their meager 1.9 tons per capita; why people from these countries be expected to give up on the quality of life and luxuries when the Americans get off scot free?
The oil kingdoms won't be giving up their emissions any time soon, tiny, overpopulated islands won't either, but even large countries such as Australia, Canada and Estonia pump CO2 in the air at twice the rate of China.
Saying "China won't do it so what's the point" is just pandering to the polluting masses to pretend they can't do a thing to change the world. Telling people that it's okay to let the tyre fire burn itself out because there's a much bigger tyre fire four streets down is still a terrible idea.
People won't give up driving cars every day, they won't give up AC and they won't give up cheap plastic. The best we can do is probably what we're doing now, using "green" technologies to delay our inevitable demise by reducing the footprint.
Green alternatives that are cheaper or as cheap as traditional items won't be available because oil is dirt cheap and easy to produce, the infrastructure is already there and everything from gas to processed food depends on oil products.
Then the relative economic benefit of ignoring climate change will further pump up the economies of countries like China who will then pollute more and gain more power, etc.
I don’t know what the solution is, if humans are even socially/politically capable of a solution, but make no mistake this is how it would play out if the western nations were all to take drastic measures against climate change.
Ultimately, the issue is that it is a competitive advantage to ignore climate change (right up until it’s too late), and global competition dictates our social evolution.
We may need green tech that is so overwhelmingly cost efficient that nobody will ever want to pollute again.
