Let’s look at three example regions: China, EU and USA. All graphs from https://ourworldindata.org/
In electricity generation China is still growing, while the others have plateaued.
Everybody’s carbon intensity is going down.
So, as an upshot, CO2 emissions per capita is a mixed bag. China was growing still recently because its actual energy usage was growing. (Trend has recently turned down since they built so much non-CO2 energy).
and if you look at the total per each area, China jumped out even more because it’s bigger. Hopefully now plateaued.
