How they compare

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

That makes Laos's figure about 1.1 times China's.

The two have swapped places 1 time across 41 shared years of data; in 1984 it was China ahead.

China ranks 12th and Laos ranks 11th of 191 countries.

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