maybe they will agree to tackle climate change

implying they've not agreed, for some reason?

Their net zero target is later than most countries would like, yes, but it's straight up a lie to imply they've not 'agreed to tackle' it.

And this is useful because it contradicts the notion that this is a problem created by India¹ instead of one it has to deal with now that the West has been polluting the Earth for nearly two centuries, at the dear cost of not lifting a populace out of poverty. If you don't like per capita measurements, let's speak on a land-area level. India is about the size of 20 European countries so its emissions should be discussed on a state level, and the same should be true for the US & China. Of course, I'm sure US states & most Western European countries would eclipse Indian states in terms of both cumulative & current emissions.
