Biggest greenhouse gas emitters by country (2023)

Where the 51 economies tracked here fall in the emissions ledger: absolute mass (who emits the most CO₂e overall) and per person (who emits the most per capita), 2023.

What the ranking shows

China leads absolute emissions at 15,970 MtCO₂e in 2023, while United Arab Emirates leads per person at 27.0 tCO₂e; the top five absolute emitters account for 64% of the 47.1 Gt tracked total. Australia is the #15 cutoff to make this list at 572 MtCO₂e.

Top emitters: absolute (MtCO₂e, 2023)

Absolute emissions identify the economies whose energy and industrial choices most directly shape the global atmospheric trajectory.

Top emitters: per capita (tCO₂e/person, 2023)

Per-capita rankings tell a different story: fossil-fuel-export and high-income economies rise to the top, while the largest absolute emitters fall when normalised by population.

A note on framing

These rankings cover the 51 major economies currently in the PlainEmissions dataset, not all ~200 countries, so "share" is the share of this tracked group, not of literal world emissions. Both lists use production-based accounting and exclude LULUCF (land use) for comparability, since EDGAR reports it separately and it carries the largest uncertainty. Per-capita figures use mid-year population estimates. Our guide on reading emissions time series explains why these framing choices materially affect the ranking.

Download the country-level EDGAR extract used for these rankings: country-emissions-statistics.csv. National reference on statistics.

According to the European Commission's Joint Research Centre, the EDGAR v8.0 dataset publishes country- and sector-level greenhouse-gas inventories on a common bottom-up model. Every figure on PlainEmissions is rebuilt from that release; no number is typed in by an editor. Absolute and per-capita rankings are computed from the same EDGAR year totals; LULUCF excluded for comparability. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error. Data current as of EDGAR 2023. EDGAR figures are production-based inventory totals for a published reference year (AR6 GWP100, LULUCF excluded on ranked surfaces) - not climate policy advice, real-time emissions, or a substitute for UNFCCC legal inventories.
