Climate change isn't driven by per-inhabitant CO2 emissions. It's driven by total CO2 emissions, of which the US outputs 12% per year.

Climate change isn't driven by human defined borders either. It's driven by total CO2 emissions. If a per-capita rate is non sensical then border based emissions are even more non sensical. Greenland only emits 0.001% of the total. Greenland is 12000x a better country than the US wow. This is exactly why per-capita is used.
Yeah and this is clearest when you consider federations. Imagine if you count the US as 50 separate countries, suddenly they are much more climate friendly! That's of course absurd.
Climate change isn’t driven by borders but energy policy is defined within them.
And no policy is gonna willingly reduce energy consumption which is directly co-related with QOL when other countries have much higher per-capita consumption. Politically humans need fairness.
We don’t need to reduce energy consumption. We need to reduce greenhouse gas emissions.
We know. There are many reasons why countries choose more polluting sources of energy. Part of which is costs. The world runs on incentives. Maybe rich countries like the US can subsidize clean energy for poorer countries like India. Because consumption is definitely not going to come down.
You say you know then directly contradict yourself by bringing up consumption again.

The United States already supports clean energy in India. India is not “poor”. It has a larger economy than the United Kingdom. 46.3% of India’s installed capacity is renewable and that mix is growing.

The notion of subsidizing a foreign country that literally has nuclear weapons is ludicrous. US voters would never stand for that.
Solar energy is currently the cheapest form of energy, cheaper than coal, cheaper than natural gas. You know the conspiracy theories about how the oil companies are keeping perpetual motion machines hidden? Solar panels are literally that. With the caveat that they only work in sunlight. So they're not great when you need energy at night. But even if you triple your costs to account for only working 8 hours a day, they're cheaper than anything else.
But the reason emissions happen is for per-inhabitant benefits. It's a very reasonable idea [0] to set a per-inhabitant goal and criticize countries exceeding that threshold (which the US would still fail at, but I'm arguing against the metric itself rather than US faults).

Take your position to something of an extreme -- the Vatican could open up 200 coal power plants for its holy Bitcoin operations and still be sufficiently less impactful to CO2 than the US that nobody would target them during climate talks. Rephrased from the other direction, each US citizen would blow their CO2 budget by buying a shirt per decade to get down to the Vatican's levels.

That's a common mental failure mode, analogous to the sorites paradox. Countries are made up of many small actors and decisions, and pretending otherwise is unlikely to help you achieve your goals.

[0] Mostly -- transitive effects like one country generating all the goods another country uses are harder to account for. Assuming we could measure perfectly though...

In context of the United States, there are a small number of actors that stand to lose billions to renewables.

I live in the Northeast. Solar reduced my grid demand by 40%. That translates to a full recoup of the investment in 60-65 months with subsidy, 100-110 without. The unsubsidized payback period is 1/3 of the projected useful life of the panels.

You know it’s a good idea because opponents big argument is safety of rooftop installers and future workers disposing of solar panels, topics that these folks DNGAF about in the least.

12% is quite low considering that the US is responsible for >20% of global industrial output.
Not really, by that metric Europe still comes out ahead.

Of course, Europe has relatively little carbon intensive industry. The US is the world's largest producer of oil, beef, and other things with an intrinsically high carbon footprint. The carbon intensity of industry is a byproduct of geography and geology.

Europe has a relatively high carbon footprint per unit of output for things like animal husbandry compared to the US, they just don't do enough of it for it to add up.

This also works in reverse, eg. US importing goods from china and therefore not being on the hook for emissions generated by those goods. ourworldindata has another page that compares the difference between consumption based emissions and territorial emissions[1]. Looking at that page, consumption based emissions are 11% higher for the US vs 27% for the EU. That makes the US look better, but it's not enough to cancel out the fact that the US is 63% more carbon intensive than the EU.

You're kinda contradicting yourself. You're right that it's about absolute numbers. But then you use a percentage.

perhaps 12% for 5% of the global population is too high. But you dont want to relate it to population. Relating to number of countries is rather non-sensical. Some are big (by productivity, area, population, etc.), some are tiny.

Making it relative to countries is useful because that is the delination along which policy is made.

Making it relative to people, IMO, only serves to obscure the fact that the US/China/etc are by far the biggest producers of emissions.

Writing climate policy with them in mind makes more sense than pushing for somewhere like Monaco to reduce emissions, even if their emissions per person are high.
