The thing is, India is emitting less than either the USA or the EU even in absolute terms. In per capita terms, it's negligible. And in total emissions to date, it's not even a blip. Even China is far better in these metrics than the US and EU.

So, at least morally, they seem to have every right to increase their emissions, and it is up to us, the largest historical polluters, to contract our economies if we are serious about both climate change and moral rights. Why should we expect to live in luxury in the EU while peasants in India live without electricity just because they can't afford a non-coal power plant?

Of course, an even better approach would be for the large historical polluters to contribute funds, manpower and know-how, freely, to build clean power and clean industry in China and other places.

And finally, I am also well aware that this is higy idealistic and none of this has any chance in hell of happening. We'll just keep pointing fingers at China and India (and the USA, speaking as an EU citizen) and avoid too much actual change.
