CHina India etc only emit loads of carbon cos they're so busy manufacturing 5h17e to fill our landfills with.
For sure, and some will be where they're manufacturing quality goods but with no regard for the environment as they do so - however efficient a Chinese factory is, if it's drawing power from the local grid its likely to be hooked up to something monstrous at the other end.
However, a growing amount is the result of their increasing middle-classedness, cars, dishwashers, lights, the whole shebang that we call living. They want it too, and are staring to get it.
So where do we go then? As regards our outsourced polltion, am I too far off base to see it as follows?: If the manufacturing countries (China and India, say) made moves to increase efficiency and reduce pollution then their costs will rise and they will lose market share - with some of it returning to the global North - good for us. With large young populations they just can't afford this.
In which case the onus is on us (Northern countries and individual consumers) to restrict our consumption of stuff. The easiest way to bring this about would be to tax imports, but any tax based on carbon produced during manufacture and shipping (or total pollution inherent in the good) would likely start a trade war, increasing costs for the UK at the same time as further alienating other major global powers - it seems lose lose.
As for China and India's own 'personal' pollution, I don't know - Chinese politicians have incredible power to bring about rapid countrywide change, but also have to keep the population onside. It's a big ask.
