I think you are reading this table wrong. The table does not list "emissions per GDP" but "GDP per emissions", which is actually the inverse.

So to get the "emissions per GDP", you have to read the table backwards, which means the United States is (among Australia, Israel, Canada) emitting more CO2 than most other developed countries, in particular Western European ones. For example, Germany produces roughly 60% more economic output (3,612 USD / ton of emissions) per CO2 emitted than the United States (2,291 USD / ton) and the United Kingdom (4,284 USD / ton) almost twice as much.

In any case, maybe a better figure would be "emissions per capita", which paints a similar picture: https://en.wikipedia.org/wiki/List_of_countries_by_greenhous...

[Update: Of course, all of these figures are not that helpful because they ignore how much CO2 emissions one "outsources" by buying products manufactured elsewhere. If you are primarily a service-driven economy, you will have much lower CO2 emissions in your country, but you will most likely still buy a lot of stuff from China etc. which will produce CO2 emissions there. That's e.g. why Switzerland is not as green as it would seem from this table.]
