How they compare

China currently reports 23.15 Mt CO2e against 20.68 Mt CO2e in United States, a difference of 2.47 Mt CO2e.

That makes China's figure about 1.1 times United States's.

The two have swapped places 3 times across 55 shared years of data; in 1970 it was United States ahead.

China ranks 1st and United States ranks 2nd of 194 countries.

Across the 6 decades both report, China averaged higher in 1 and United States in 5.

Head to head by decade

A measure of annual emissions of nitrous oxide (N2O), one of the six Kyoto greenhouse gases (GHG), from the transportation sector (subsector of the energy sector) including IPCC 2006 codes 1.A.3.a Civil Aviation, 1.A.3.b_noRES Road Transportation no resuspension, 1.A.3.c Railways, 1.A.3.d Water-borne Navigation, 1.A.3.e Other Transportation. The measure is standardized to carbon dioxide equivalent values using the Global Warming Potential (GWP) factors of IPCC's 5th Assessment Report (AR5).
