This is a nice race to follow: the evolution of carbon intensity of electricity.
Before 2010 Denmark and the Netherlands were still higher than world average. Then from 2010 Denmark got serious about decarbonising. In the Netherlands we waited until 2018 but we are finally reducing it quickly!
In 2022 it was lower than Germany for the first time. Germany's carbon intensity increased in the last 2 years.
Still a long way to go to reach France and Sweden at the bottom.
Final goal 0!
CO2 emissions per person in the world peaked in 2012 and are rather stable since then.
In the EU it is decreasing but it is still higher than the world average.
The fact that the EU uses less than half CO2 per person than the US is actually a good example for me that you can have a better quality of life and less CO2.

@DewiLeBars There are some really huge state-to-state differences in the US as well. California is at 9.3 tons of CO2e per capita (counting all greenhouse gases) which is probably fairly similar to that in Europe.

The big difference is that the state has mandatory energy efficiency rules for buildings (title 24) and appliances.
