China has 4 times the population. In any rational divvying up of the world's total emissions allowance by country China's share would be 4 times that of the US, but they are only emitting twice what the US is emitting.

Both are over their fair share, but the US is over by a larger factor so is farther behind on getting to where they need to be.

(This is not taking into account trade. Divvying up the world emissions budget by population gives the fair amount for each country if there is no trade. If there is trade the best way to handle it is probably to count the emissions for making things in country X that get consumed in country Y as being emissions in Y. With that correction China comes out even better).

Assigning blame and guilt is pointless. Just look at how well it has worked to motivate the US to change. That is to say, not at all.

The only thing moving the needle is renewables and nuclear generating power more cheaply than fossil fuels, so it becomes stupid to not switch to them even if you have no regard for the long term health of the environment.

It's not about assigning blame.

Per capita emissions give us a better idea of which groups of people require the largest change in their lifestyle in order to hit net zero. The current numbers suggest that the typical person in the US will have to do a lot more to hit net-zero than the typical person in China. Obviously, you can do better and estimate per capita emissions for each province/state/city or by wealth level. For instance, in many poor countries, most of their emissions come from the top 5-10% of the population. Everyone else emits basically nothing.

On the other hand, the total emissions of a country, absent other information, has little actionable value. It can only be uses to assign blame, so quite useless.

Doesn't matter if the people with the biggest emissions don't personally feel any urgency to change.
That still sounds like assigning blame and a vague call to "change lifestyle", instead of concrete action plans for energy, manufacturing, transportation and agricultural sectors. That is where the bulk of emissions are, not some billionaire's yacht or private jet.

Why?

A huge portion of China's emissions come from making things for people that aren't in China. The argument is that if a Chinese factory makes only widgets used in the US, those emissions from the Chinese factory are probably more accurately counted as US emissions.

Its like saying that you are 0 emissions because you have an electric car with no tailpipe while ignoring where the electricity is coming from.

The counter argument is that they'd have mass unemployment and would be in poverty without it. Virtually all rapid modern industrialization is reliant on exporting to foreign markets so characteizing it as American emissions is largely a misomer as it is really global emissions.
You're not actually addressing the accounting question though. The argument isn't about the economic benefits or consequences of manufacturing, it's simply about where we assign the carbon emissions in an accounting system.

Whether Chinese workers benefit economically from manufacturing exports doesn't change the fact that when a US consumer buys a product made in China, we could reasonably count those manufacturing emissions as US consumption-based emissions rather than Chinese production-based emissions.

This is really a question of "but for" causation: but for US consumer demand for these products, would these specific manufacturing emissions have occurred? If the answer is no, then there's a strong case for counting them as US emissions regardless of where the factory happens to be located.

Your point about global emissions sidesteps the question entirely. Of course all emissions are ultimately global in their climate impact, but for policy and measurement purposes we still need accounting frameworks. The question is whether production-based or consumption-based accounting gives us a more accurate picture for policy decisions.

The unemployment and poverty argument, while valid for other discussions, doesn't really bear on which accounting method better reflects responsibility for emissions.

While I fundamentally disagree, do you really not see how that would then mean all Chinese emissions are therefore a result of the United States? So that's... worse?
What? No, because China is also exporting to other markets. The counterfactual is that we don't do global industrialization and let the global poor remain poor.
The US introduced China to western manufacturing markets. So if they would otherwise be poor and non-industrialized, the US is responsible for it all.

We can't claim we rose them from poverty while also denying culpability for the consequences thereof...

Though I think everyone is just saying Chinese emissions should be counted, proportionally, against the people they're making products for. And the US is one of their biggest customers.

Because China makes more things that are used in the US than the other way around.
>> China has 4 times the population. In any rational divvying up of the world's total emissions allowance by country China's share would be 4 times that of the US, but they are only emitting twice what the US is emitting.

For now. Look at the rate of growth on their per capital carbon emissions. Then compare it with that of the USA.
