How they compare

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

That makes Cameroon's figure about 1.1 times Bulgaria's.

The two have swapped places 9 times across 45 shared years of data; in 1980 it was Bulgaria ahead.

Bulgaria ranks 122nd and Cameroon ranks 120th of 191 countries.

Bulgaria has averaged higher in every one of the 5 decades both report.
