Can you tell everyone what their per capita emission is? While you're at it, compare that with the US per capita emissions. Also let us know the accumulated emissions for China and US in the last 50 years.
Thanks.
Thanks.
I would expect air conditioning to also be among the easier energy uses to match with solar power as we go forward. Better building design and more efficient AC devices also make a huge difference.
China is currently building out all of this renewable energy and EVs, when the early industrial powers didn't, not out of the goodness of their hearts, but because it is now the easy way.

The shallow decline in 2015 and 2016 was due to a slump that followed a round of stimulus measures, while zero-Covid controls caused a sharper fall in 2022.
(Or not, there's at least theoretical paths to make those examples better, this is just meant to moderate hope rather than to deny it entirely).
If we focus on rates of growth, China is building much more solar and nuclear than the US per-capita. And they don't have as much available domestic gas which with shorter carbon chains makes much less CO2, and that's the big problem. The US has twice as many natural gas reserves as China, with 1/4 the population, so, post-dissemination of fracking technology, that's largely down to geographical luck.
There's going to be big spikes in data center energy consumption in both countries. It's still somewhat marginal at the moment at a little over 4% here and less there but it is going to be a main driver of energy consumption growth going forward.
Banning China from leading nodes may result in doubling or more their consumption in this area as a direct US policy outcome.
The lack of a single world government is why.
Agreements between nations are only enforced by honour, and while that's more than nothing, it's not great.
The practical outcome of this is that who is "allowed" to do anything is dynamic, and who may do something the most can be inverted extremely quickly.
Indonesia: 275M / 650M ton / 2.3 ton
Pakistan: 240M / 225M ton / 1 ton
Nigeria: 220M / 110M ton / 0.5 ton
Brazil: 215M / 475M ton / 2.2 ton
I can go on and on about the countries that are emitting less than the US. People and animals live in areas that are liveable. So countries near the equator and fertile countries will always be more populous. So how else do you propose we compare countries? Which are themselves mostly arbitrary lines as far as the earth is concerned - so why chunk by countries? It has to be per person right?

"My maths" is that countries cannot use per captia stats as an excuse to produce tons of pollution. Would it be acceptable for every country to pollute as much as China if every country in the world had 1.5b people? No it wouldnt we would say thats to many people.
If a country wants to have 5million people and produce 15(units) of co2 per captia thats fine that is not globe threatening levels of pollution its living within their means. However if that country were to have 2 billion people and had a per captia of 10(units) I would say they need to significantly reduce that to about 2.5(units).
Whereas you'd be making the argument that the country is actually doing a lot better even though they produce 20billion(units) total.
The US is fairly high but below Canada, Russia, and many Middle Eastern countries. US emissions have also consistently fallen for the past 25 years or so.
They aren't relevant to the climate, but they are relevant to how much energy and wealth you allow each person to have.
Does a person in China deserve to have less energy or wealth than a person in America?
There is some per capita carbon emissions budget such that if each human on earth stayed within that budget, climate change could be mitigated[0]. The average Chinese person exceeds that budget, but does so by significantly less than the average American. So the average American is more at fault for climate change than the average Chinese person is.
Of course, your second claim, that this is a global issue, is correct. But if we solved the global issue in a fair way, China would still emit a few times more CO2 than the US.
0: “Mitigated” rather than totally solved, because to go back to pre-industrial temperatures the budget would have to be negative. But let’s say we’re talking about staying within 2C or some similar goal.
Why are some people entitled to more than others based on where they live?
The US is the world leader in per capita CO2 emissions. Has been for over a century. Only in 2021 China has reached 8t per capita. Do you know when the US reached that figure? 1899.
The inhabitants of the US, and of the UK before it, have been enjoying the benefits of energy-intensive industry for hundreds of years. But the externality of that process - the emissions - is a burden shared with everyone else in the world. As others have mentioned, the planet does not care who emitted CO2.
None of those countries is in a position to criticize the emissions of China or India or Brazil or whatever other country.
