How they compare

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

That makes Denmark's figure about 1.2 times Norway's.

The two have swapped places 6 times across 55 shared years of data; in 1970 it was Denmark ahead.

Denmark ranks 177th and Norway ranks 180th of 191 countries.

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