Switzerland in context

0.11% vs 0.08%

Share of people vs share of CO₂

Switzerland is home to 0.11% of the world’s population and produces 0.08% of its fossil CO₂, so its share of emissions is smaller than its share of people.

−27%

Change since 1990

Emissions in 2024 were 27% lower than in 1990, the baseline year of the Kyoto Protocol (44.1 Mt then). World emissions rose 70% over the same period.

118 Mt

Consumption-based CO₂ (2023)

Counting the CO₂ in goods it imports and exports, Switzerland was responsible for 118.3 Mt in 2023, 270% more than the 32.0 Mt produced at home: it is a net importer of emissions.

94 g

CO₂ per kWh of energy

Each kilowatt-hour of primary energy used in Switzerland came with about 94 g of CO₂ in 2024 (world: 218 g), pointing to a much cleaner energy mix than the world average.

0.06 kg

CO₂ per dollar of GDP

Its economy emitted 0.06 kg of CO₂ for each dollar of output in 2022 (adjusted for purchasing power), 80% below the world average of 0.29 kg.

Questions and answers

How much CO₂ does Switzerland emit?

Switzerland emitted 32.1 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 Switzerland’s CO₂ emissions per person?

Switzerland emits 3.6 tonnes per person, 24% below the world average of 4.7 t. Per-person emissions divide the national total by population (8.9 million people in 2024).

Are Switzerland’s CO₂ emissions rising or falling?

Emissions were roughly flat in 2024 (+0.3% on 2023). Compared with 2005, emissions are down 30%. Emissions peaked in 1973 at 46.2 million tonnes and are now 31% lower.

What is the main source of CO₂ emissions in Switzerland?

Oil is the largest source, at 76% of Switzerland’s fossil and industry CO₂ in 2024 (24.4 million tonnes).

What are Switzerland’s consumption-based CO₂ emissions?

About 118.3 million tonnes in 2023, 270% more than the 32.0 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 Switzerland contributed to historical CO₂ emissions?

Since 1750, Switzerland has emitted about 3 billion tonnes of fossil CO₂, 0.2% of the world total, the 55th largest historical contribution.
