Cambodia in context

0.22% vs 0.06%

Share of people vs share of CO₂

Cambodia is home to 0.22% of the world’s population and produces 0.06% of its fossil CO₂, so its share of emissions is smaller than its share of people.

+1,585%

Change since 1990

Emissions in 2024 were 1,585% higher than in 1990, the baseline year of the Kyoto Protocol (1.3 Mt then). World emissions rose 70% over the same period.

39 Mt

Consumption-based CO₂ (2023)

Counting the CO₂ in goods it imports and exports, Cambodia was responsible for 39.1 Mt in 2023, 83% more than the 21.4 Mt produced at home: it is a net importer of emissions.

250 g

CO₂ per kWh of energy

Each kilowatt-hour of primary energy used in Cambodia came with about 250 g of CO₂ in 2024 (world: 218 g), pointing to a more fossil-heavy energy mix than the world average.

0.32 kg

CO₂ per dollar of GDP

Its economy emitted 0.32 kg of CO₂ for each dollar of output in 2022 (adjusted for purchasing power), 1.1× the world average of 0.29 kg.

Questions and answers

How much CO₂ does Cambodia emit?

Cambodia emitted 21.9 million tonnes of CO₂ from fossil fuels and industry in 2024, 0.1% of global emissions. That is about 1 tonnes every second.

What are Cambodia’s CO₂ emissions per person?

Cambodia emits 1.2 tonnes per person, 74% below the world average of 4.7 t. Per-person emissions divide the national total by population (17.6 million people in 2024).

Are Cambodia’s CO₂ emissions rising or falling?

Emissions rose 2.3% in 2024 compared with 2023. Compared with 2005, emissions are up 895%. 2024 was the highest year on record.

What is the main source of CO₂ emissions in Cambodia?

Oil is the largest source, at 45% of Cambodia’s fossil and industry CO₂ in 2024 (9.8 million tonnes).

What are Cambodia’s consumption-based CO₂ emissions?

About 39.1 million tonnes in 2023, 83% more than the 21.4 million tonnes emitted within its borders, because it imports more carbon-intensive goods than it exports. Consumption-based accounting adds the emissions embodied in imports and subtracts those in exports.

How much has Cambodia contributed to historical CO₂ emissions?

Since 1750, Cambodia has emitted about 0 billion tonnes of fossil CO₂, 0.0% of the world total, the 122nd largest historical contribution.
