Why this matters
At 950 MtCO2e in 2022, Iran ranks among the largest greenhouse-gas emitters tracked by EDGAR v8.0. Per-capita emissions of 10.80 tCO2e/person provide a normalized comparison across countries of different sizes — useful for cross-country policy debate but obscuring absolute climate impact. Energy and Industry account for the majority of the total, consistent with the bottom-up sectoral model EDGAR applies globally.

Methodology
Iran's emissions are loaded from EU EDGAR v8.0 (Joint Research Centre, 2024 release). Values are stored as megatonnes CO2-equivalent using IPCC AR6 GWP100 multipliers (CO2=1, CH4=27.9, N2O=273). Native-unit gas quantities are preserved alongside in emissions_records.value_native. The 2017-2021 reconstruction applies a country-specific growth trend to the 2022 baseline; full multi-year EDGAR ingest replaces this in 10-load-edgar-full.mjs. See methodology for full pipeline detail.

FAQ
How much CO2-equivalent did Iran emit in 2022?
Iran's total 2022 greenhouse-gas emissions were 950 MtCO2e per EU EDGAR v8.0 (2024 release), summed across 8 IPCC sectors and 3 gases (CO2, CH4, N2O) using AR6 GWP100 weighting.
What is Iran's per-capita emission level?
Per-capita emissions are 10.80 tCO2e per person in 2022, derived from total emissions divided by population of 88,000,000.
Which sector dominates Iran's emissions?
The largest emitting sector for Iran in 2022 was Energy at 323 MtCO2e, accounting for 34.0% of national emissions per EU EDGAR sectoral data.
Disclaimer
PlainEmissions presents greenhouse-gas data for research and journalism. Emissions accounting is inherently uncertain — figures depend on the upstream measurement methodology, sectoral assumptions, and reporting vintage.
