How they compare

Kazakhstan currently reports 0 Mt CO2e per US$ of GDP against 0 Mt CO2e per US$ of GDP in Romania, a difference of 0 Mt CO2e per US$ of GDP.

That makes Kazakhstan's figure about 1.1 times Romania's.

The two have swapped places 6 times across 35 shared years of data; in 1990 it was Kazakhstan ahead.

Kazakhstan ranks 92nd and Romania ranks 95th of 194 countries.

Kazakhstan has averaged higher in every one of the 4 decades both report.
