Iran in context

1.1% vs 2.1%

Share of people vs share of CO₂

Iran is home to 1.1% of the world’s population and produces 2.1% of its fossil CO₂, so its share of emissions is larger than its share of people.

+275%

Change since 1990

Emissions in 2024 were 275% higher than in 1990, the baseline year of the Kyoto Protocol (211.1 Mt then). World emissions rose 70% over the same period.

669 Mt

Consumption-based CO₂ (2023)

Counting the CO₂ in goods it imports and exports, Iran was responsible for 668.6 Mt in 2023, 15% less than the 789.7 Mt produced at home: part of its output is consumed elsewhere.

221 g

CO₂ per kWh of energy

Each kilowatt-hour of primary energy used in Iran came with about 221 g of CO₂ in 2024 (world: 218 g), pointing to an energy mix close to the world average.

0.49 kg

CO₂ per dollar of GDP

Its economy emitted 0.49 kg of CO₂ for each dollar of output in 2022 (adjusted for purchasing power), 1.7× the world average of 0.29 kg.

Questions and answers

How much CO₂ does Iran emit?

Iran emitted 792.6 million tonnes of CO₂ from fossil fuels and industry in 2024, 2.0% of global emissions. That is about 25 tonnes every second.

What are Iran’s CO₂ emissions per person?

Iran emits 8.7 tonnes per person, 1.8× the world average of 4.7 t. Per-person emissions divide the national total by population (91.6 million people in 2024).

Are Iran’s CO₂ emissions rising or falling?

Emissions were roughly flat in 2024 (+0.4% on 2023). Compared with 2005, emissions are up 70%. 2024 was the highest year on record.

What is the main source of CO₂ emissions in Iran?

Gas is the largest source, at 62% of Iran’s fossil and industry CO₂ in 2024 (492.7 million tonnes).

What are Iran’s consumption-based CO₂ emissions?

About 668.6 million tonnes in 2023, 15% less than the 789.7 million tonnes emitted within its borders, because part of what it produces is exported and consumed in other countries. Consumption-based accounting adds the emissions embodied in imports and subtracts those in exports.

How much has Iran contributed to historical CO₂ emissions?

Since 1750, Iran has emitted about 22 billion tonnes of fossil CO₂, 1.2% of the world total, the 15th largest historical contribution.
