But since we’ll never get China and India off of coal, I guess we have to do something.

This is a bad and uninformed take.

Per person, emissions in both China and India are still substantially lower than almost all developed countries. India’s per person emissions are less than one-quarter of the global average, and roughly one-tenth of those of the US. Close to a quarter of all carbon emissions come from manufacturing products which are exported and consumed in other countries. Textiles and clothes exported from India and south Asia account for over 4% of global emissions.
Labelling India and China as the chief villains of COP26 is a convenient narrative. The financial aid which rich countries promised yet failed to deliver as part of the Paris Agreement signed in 2015 was supposed to help developing countries dump coal for cleaner sources of energy. And while the world berated India and China for weakening the Glasgow Climate Pact’s coal resolution, few questioned the fossil fuel projects being floated in developed nations, like the UK’s Cambo oilfield and the Line 3 oil pipeline between Canada and the US.

And that's without even going back to look at imperialism and its impacts on those countries, and why they're now having to play catch up with the west (who not only did our fair share of polluting during our own industrial revolutions, but still continue to do so pretty much freely), mostly to provide for the west.

This, like the overpopulation myth, are nothing more than racist distractions created by the rich and powerful to get us to blame "others" rather than look for who is really at fault - them (Edit to clarify: and by them I mean all obscenely rich and the governments they control, faux communists included).

It's difficult to get China and India off coal because they're doing most of the world's manufacturing and some processes are currently impossible without it. But 'we' exported manufacturing to Asia and 'we' buy the products the coal is used for. 'We' don't get to wriggle out of responsibility by pretending that a couple of low and middle income countries are somehow responsible for 'our' excessive consumption.

Not emitting is not that easy. We are in a transition period at the moment. Electric vehicles are here but we don't have all the infrastructure needed to support them. Let alone the fact that battery tech is not developing as fast as we need it to.

Right now liquid fuels still have the advantage of greater energy density. If we could move to hydrogen fuels that would be cool, and we could repurpose existing petroleum facilities.

But who knows which way the tech is going to go. The only sure thing is that we are in for a wild ride one way or the other.

Western countries are just as guilty, if not more. We contributed terribly for several hundred years, and still today net carbon use is still increasing in developed countries. It's just not increasing quite as much as before.

China's usage of coal is huge, but it's proportiojn has dropped from 75+% in 1990 to around 55%. It's slow progress - it may accelerate. The problem is the rest of the world exports so much of its manufacturing requirements to China.

Yep, it takes about 30 years to see the effects, what we're dealing with right now is the 1993 emissions, if we stopped using all fossil fuels right this instant things would continue to get worse well into the 2050s.
