Analysis
In 2024, nitrous oxide (n2o) emissions from transport (energy) in Australia stood at 1.64 Mt CO2e.
Compared with earlier readings it is up 3.4% on the previous year and up 22.9% over ten years.
Over the whole period, nitrous oxide (n2o) emissions from transport (energy) in Australia peaked at 3.51 Mt CO2e in 1999 and was at its lowest, 0.4037 Mt CO2e, in 1971.
That places Australia 11th out of 194 countries with data for 2024, putting it in the top 10%.
The long-run direction has been consistently rising across the 55 years of available data.

About this data
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).
