Singapore in context

0.07% vs 0.14%

Share of people vs share of CO₂

Singapore is home to 0.07% of the world’s population and produces 0.14% of its fossil CO₂, so its share of emissions is larger than its share of people.

+24%

Change since 1990

Emissions in 2024 were 24% higher than in 1990, the baseline year of the Kyoto Protocol (43.5 Mt then). World emissions rose 70% over the same period.

187 Mt

Consumption-based CO₂ (2023)

Counting the CO₂ in goods it imports and exports, Singapore was responsible for 186.9 Mt in 2023, 266% more than the 51.1 Mt produced at home: it is a net importer of emissions.

51 g

CO₂ per kWh of energy

Each kilowatt-hour of primary energy used in Singapore came with about 51 g of CO₂ in 2024 (world: 218 g), pointing to a much cleaner energy mix than the world average.

0.11 kg

CO₂ per dollar of GDP

Its economy emitted 0.11 kg of CO₂ for each dollar of output in 2022 (adjusted for purchasing power), 63% below the world average of 0.29 kg.

Questions and answers

How much CO₂ does Singapore emit?

Singapore emitted 53.9 million tonnes of CO₂ from fossil fuels and industry in 2024, 0.1% of global emissions. That is about 2 tonnes every second.

What are Singapore’s CO₂ emissions per person?

Singapore emits 9.2 tonnes per person, 2.0× the world average of 4.7 t. Per-person emissions divide the national total by population (5.8 million people in 2024).

Are Singapore’s CO₂ emissions rising or falling?

Emissions rose 5.5% in 2024 compared with 2023. Compared with 2005, emissions are up 36%. Emissions peaked in 1994 at 60.1 million tonnes and are now 10% lower.

What is the main source of CO₂ emissions in Singapore?

Oil is the largest source, at 59% of Singapore’s fossil and industry CO₂ in 2024 (31.8 million tonnes).

What are Singapore’s consumption-based CO₂ emissions?

About 186.9 million tonnes in 2023, 266% more than the 51.1 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 Singapore contributed to historical CO₂ emissions?

Since 1750, Singapore has emitted about 2 billion tonnes of fossil CO₂, 0.1% of the world total, the 65th largest historical contribution.
