That sorta requires you to lead by example, first.

Does it? The US is currently compelling Russia to give up its claims in eastern Ukraine, despite occupying whole parts of Syria and other places itself

I mean what do you propose western nations do? Nothing? Yeah stupid measures like removing straws from restaurants make 0 difference, but pushing for more fuel efficient vehicles and cleaner sources of electricity seems like a worthwhile effort without much QoL sacrifice. Green infrastructure (i.e. reducing car dependence) also seems to improve quality of life in many places, so I would argue we should be trying to d…

How do you diplomatically convince another country that their people need to have a lifestyle and standard of living that emits a fraction of the CO2 that your people emit?

They’re doing it to us (Americans)… stands to reason that it can be done to others

Because it's non-negligible source of warming greenhouse gases that is completely avoidable - we have plenty of substitutes available to us with lower global warming potential. Releasing 1 kg of CFC-13 will trap the same amount of heat as 14,000 kg of CO2. Project Drawdown lists managing refrigerants as one of the top 10 solutions to limit warming in both 1.5 and 2C scenarios. https://www.drawdown.org/solutions/table…

Yes, but the point is the danger from the warming contribution is less than the danger from an ozone hole, so why focus on the warming? Unless the ozone depletion is below the recovery rate.

The article suggests that it is currently below the recovery rate (but only just).

Why can it not be countries that don't care just using CFCs still?

China is mentioned as having been a likely culprit in the past. I don't understand why Westerners are so keen to make major sacrifices to quality of life in the name of fighting climate change when nothing we do will make a statistically significant impact in the long run with major population centers like China, India, and Nigeria continuing to grow more wealthy with rapidly increasing demand for reliable, 24/7 ener…

Because we still all gotta share this earth together, and destroying it faster helps no one. How is that difficult to understand? Do you honestly think that just going "fuck it, let's keep polluting because other people are doing the same" is really going to get us to a better place?

We've already reduced estimated warming from ~6 degrees to ~3.5 degrees or so. It's not enough, but it's a hell of a lot better than statistically insignificant.

Last I checked China, India, etc. still have a much lower per capita carbon footprint than the US.

They're looking to catch up! They don't want to remain poor, after all.

They don't need to come anywhere near US levels of per capita emissions to stop being poor. Here are some countries that are generally considered to be reasonably wealthy, and their per capita emissions as a percent of US per capita emissions:

  63% Japan
  61% Germany
  36% UK
  30% Switzerland
India is at 12% now and China at 48%.

Not every culture values virtue signaling as much as the current regime in the west; performative acts are not necessarily going to influence other cultures such as China, etc.

Do you see all investments in green energy and waste reduction - even those that are creating material effects at a national level - as performative?

They are just as much looking to leapfrog and have opportunities to do so. Without massive numbers of oil and coal lobbyists, as just one example, it is far easier for them to jump straight into massive renewable energy sources and skip a lot of Western CO2 mistakes in their "bootstrapping" processes.
