No, but if some people are outputting way more CO2 than others, these are the ones we should be focussing on first.

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.

Yes China is outputting way more C02 than the next 6 biggest pollutors combined. Lets focus on them first. They are the only ones not reducing their emission growth.

Serialization is a losing strategy here. “Focus” is irrelevant. We need fundamental shifts in energy production.
