How they compare

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

That makes Iran's figure about 2.5 times Libya's.

The two have swapped places 4 times across 55 shared years of data; in 1970 it was Iran ahead.

Iran ranks 2nd and Libya ranks 3rd of 191 countries.

Iran has averaged higher in every one of the 6 decades both report.
