Japan: large EDGAR inventory · 1,044 MtCO₂e

In 2023, Japan emitted 1,044 MtCO₂e (8.42 t per person, 0.25 t per $1K GDP) - energy led at 41% and carbon dioxide dominated the gas mix at 90%. EU EDGAR v8.0, excludes land use.

Corpus placement

Japan's absolute footprint (#7 of 51) in 2023 outweighs how carbon-intensive its economy actually is — GDP intensity ranks far lower at #38 / 51, so scale, not inefficiency, drives the total.

Year-to-year inventory change

What changed between 2022 and 2023

2022 → 2023
  • Japan's EDGAR greenhouse-gas total fell from 1,111 MtCO₂e in 2022 to 1,044 MtCO₂e in 2023 in the EU EDGAR v8.0 (2024) extract, a change of −66.5 MtCO₂e (−6.0%).
  • Japan's energy total fell from 470.1 MtCO₂e in 2022 to 432.7 MtCO₂e in 2023 in the EU EDGAR v8.0 (2024) extract, a change of −37.4 MtCO₂e (−8.0%).
  • Japan's methane total fell from 57.9 MtCO₂e in 2022 to 56.7 MtCO₂e in 2023 in the EU EDGAR v8.0 (2024) extract, a change of −1.18 MtCO₂e (−2.0%).

Scale versus efficiency

Absolute inventory signature

Japan's absolute inventory is the standout: 1,044 MtCO₂e puts it in the upper Mt tercile among tracked EDGAR economies (≥524.6 Mt).

Japan's 1,044 MtCO₂e total in 2023 ranks #7 of 51 economies by absolute scale, but its GDP intensity ranks far lower at #38 — the total is driven more by the size of the economy than by how carbon-intensive each dollar of output is.
