Analysis
The most recent figure for greenhouse gas emissions in Iran is 1.01 billion tonnes of CO₂ equivalents, measured in 2024. That is the highest value across all 175 years on record.
Compared with earlier readings it is up 1.1% on the previous year and up 28.4% over ten years.
Over the whole period, greenhouse gas emissions in Iran peaked at 1.01 billion tonnes of CO₂ equivalents in 2024 and was at its lowest, 9.93 million tonnes of CO₂ equivalents, in 1850.
That places Iran 7th out of 199 countries with data for 2024, putting it in the top 10%.
The series is highly variable year to year, so single readings are best treated with caution.

About this data
Greenhouse gas emissions are measured in tonnes of carbon dioxide-equivalents over a 100-year timescale.
