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.
