How they compare

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

That makes Nepal's figure about 1.1 times Samoa's.

The two have swapped places 7 times across 55 shared years of data; in 1970 it was Samoa ahead.

Nepal ranks 37th and Samoa ranks 38th of 191 countries.

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